CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This Non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No(s). 100127229 filed in Taiwan, Republic of China, Aug. 1, 2011, the entire contents of which are hereby incorporated by reference. 
       FIELD OF THE INVENTION 
       [0002]    The present invention relates to a composition for inhibiting proline-directed protein kinase FA/glycogen synthase kinase 3 alpha (PDPK FA/GSK-3α). 
       BACKGROUND OF THE INVENTION 
       [0003]    Oligomer procyanidins (OPC) is a family of bioflavonoids, a type of polyphenols. This substrate is generally exhibited in plants, and is often exhibited in fruits, nuts, seeds, flowers, bark and vegetables, especially high in grape seed (Wilska, 1996; Pekic et al., 1998; Yamakoshi et al., 1999; Bruno et al, 2000; Yamakoshi, 2002; Shao et al., 2003) and pine bark extract. Recently, all kinds of studies indicate there are anti-oxidant components in bioflavonoids, which have protection functions of anti-cancer, anti-allergy, etc. 
         [0004]    In early stage, the OPC was used as drug, such as: Endotelon for treating microvascular circulation abnormality, besides, enhancing immune system and circulation system. OPC is general used for treating high blood pressure, heart disease prevention, vascular disease and decreasing the diabetic retinopathy in abroad (Motoaki et al., 1999). In addition, there are many applications in beauty products such as impediment to the injury of UV and reduction the break of collagen and elastic fibril in the skin, in order to prevent the wrinkle caused by skin collapse and to protect skin from aging, and then to achieve the effect of anti-aging (Garbacki et al., 2002). OPC is usually used in anti-oxidation, mostly includes anti-peroxidation and free radical cleaning, especially shows the apparent effect on free radical cleaning. Besides, OPC has effect on inhibirion of bacteria and cancer cell proliferation, and anti-inflammation (Madhavin et al., 1998; Hassan et al., 2000; Wollgast et al., 2000). 
         [0005]    OPC is not a single compound, it is composed of a series of compounds which includes high and low molecule weight compounds, wherein the low molecule weight compounds comprise catechin and epicatechin, dimer (procyanidi series B), polyhydroflavan-3-ol, trimmer (procyanidin C series); the high molecule weight compounds comprise tannins (condensed tannins) and polymers (polyhydroflavan-3-ol). However, every monomer is linked by carbon-carbon bound (Balde et al., 1995; de Bruyne et al., 1999; Bennie et al., 2000; Gabetta et al., 2000). 
         [0006]    Taking grape seed for example, the chemical structure is mainly constructed by flavan-3-ol, wherein the most important component is oligomer procyanidins (OPC). The OPC can be classed as monomeric, oligomeric and polymeric proanthocyanidins by degree of polymerization (DP). And the feature of OPC is mostly related to its structure, especially related to the degree of polymerization (Haslam, 1974; Robichaud et al., 1990; Rigaud et al., 1993; Hor et al., 1996; Baoshan et al., 1998; Le Roux et al., 1998). The basic monomer of OPC is flavan-3-ol, which is called as catechin or the other stereochemical isomer—epicatechin. The OPC itself has little activity (Poorter et al., 1986). However, when they combine as dimers or trimmers, which is an oligomer, so called as OPC or Procyanidin (Foo et al., 1999), which has high biological activity. Two monomers are called as dimers, and three monomers are called as trimmers, and four monomers are called as tetramers and so forth, if the polymer is composed of more than four monomers, it is called polymeric proanthocyanidins. However, the OPC in the grape seed are different types of compounds which are composed of 2˜17 monomers (Prieur et al., 1994). 
         [0007]    PDPK FA was originally identified as a specific membrane and cytoplasmic activating factor A of ATP.Mg-dependent protein phosphatase but has subsequently been characterized as a multisubstrate/multifunctional proline-directed protein kinase (PDPK) possibly associated with human cancers. In recent years, the immunohistochemical study revealed that PDPK FA was not only highly expressed in histologically conventional tumor cells but also aberrant accumulated in a signaling interplay network (named as lethal system) preferably epithelial-mesenchymal transition (EMT) or tumor-stroma coevolutional communication (TSCC) associated with aberrant expression of PDPK FA in other tumor-associated cells such as bone marrow-derived cell (BMDC) or cancer-associated fibroblast (CAF) or circulating tumor cell (CTC) or circulating tumor stem cell (CTSC) or epithelial tumor cell (ETC) or epithelial tumor stem cell (ETSC) or hematopoietic stem/progenitor cell (HSPC) or mesenchymal stem cell (MSC) or mesenchymal tumor cell (MTC) or mesenchymal tumor stem cell (MTSC) or tumor-associated macrophage (TAM) useful in detecting micrometastasis and PDPK FA in bone marrow-derived stem cell (BMDSC; named as lethal cell) is useful for monitoring disease status and therapy responses in various types of cancer patients regardless of the etiological origin of the cancer. Furthermore, PDPK F A /GSK-3α in bone marrow cell (BMC; named as unhealthy BMC) has been established as the diagnostic indicator for predicting disease predisposition from very early-stage aberrant wound healing, chronic inflammation and immune disorder towards end-stage fibrotic disease or neoplasia in cancer-free human subjects and has been established as a master integrator of stresses and inflammation responses essential for development and progression of certain illnesses (vicious cycle). 
         [0008]    As used in the present invention, the term “unhealthy BMC” refers to a cell preferably a BMC associated with aberrant expression of PDPK F A /GSK-3α. Please check our previous U.S. patent application Ser. No. 12/495,967 for further information. And the term “lethal cell” refers to a BMDSC associated with an aberrant intracellular accumulation of PDPK F A /GSK-3α. Please check our previous U.S. patent application Ser. No. 12/553,035 for further information. And the term “lethal system” refers to a signaling interplay network preferably epithelial-mesenchymal transition (EMT) or tumor-stroma coevolutional communication (TSCC) associated with aberrant expression of NFA in said marker cell. Please check our previous U.S. patent application Ser. No. 13/186,100 for further information. Moreover, the term “vicious cycle” indicates pathophysiological condition induced by PDPK F A /GSK-3α related cytokines expression when cells are under pressure and inflammation state. Please check our previous U.S. patent application Ser. No. 13/166,715 for further information. 
         [0009]    However, due to high sequence homology in kinase domain, PDPK FA was regarded as a subtype of GSK 3 (glycogen synthase kinase 3), and renamed as GSK-3α. Although GSK 3/GSK-3β and PDPK FA/GSK-3α have long been regarded as two closely-related signaling molecule, albeit structurally-similar in kinase domain, they are not functionally-equivalent or -redundant as previously conceived in drosophila and rodents when based on human clinical studies as demonstrated in this application. Moreover, intensive study and most attention have focused on GSK-3β but entitled GSK3 without further specifications in many areas of research and suppression of this kinase may cause tumorigenesis which raises a serious issue concerning how to treat diabetes without causing cancer. As a result, the unique role of PDPK FA has been overlooked for more than a decade and the current development of GSK-3 inhibitor is restricted in inhibiting activity of GSK-3α/β. The specific inhibitors of PDPK FA/GSK-3α have never been produced. Thus, to develop an inhibitor of PDPK FA/GSK-3α is an urgent case. 
       SUMMARY OF THE INVENTION

       EMBODIMENTS 
     Example 1 
     The Inhibition Effect of PDPK F A /GSK-3α by OPC 
       [0041]    [Materials and Methods] 
       1. The Production, Identification and Features of Anti PDPK F A /GSK-3α Antibody 
       [0042]    PDPK F A /GSK-3α amino acid sequence C-terminal 471˜483 a.a-QSTDATPTLTNSS was synthesized by Peptide Synthesizer (Model: 9050, Milligen, Bedford, Md.). According to the process Reichlin (1980) described, in order to couple the peptide onto bovine serum albumin, using glutaraldehyde as an inter-connector to connect the cysteine to NH 2 -terminal. Then, the product was purified by Affinity Chromatography and neutralized by PDPK F A /GSK-3α amino acid sequence C-terminal 471˜483 a.a. After the experiment, we demonstrated that this anti-PDPK F A /GSK-3α antibody performs immune specificity. 
       2. Immunohistochemistry Analysis 
       [0043]    Tissue sections (5 μm) of formalin-fixed, paraffin-embedded tissue containing tumor that showed the maximum extent of tumor cells were dewaxed in xylene and rehydrated in graded concentrations of ethanol. Endogenous peroxidase was blocked with 3% hydrogen peroxide followed by bovine serum albumin blocking for 5 minutes. The slides were next incubated with anti-PDPK F A /GSK-3α antibody (2 μg/mL) diluted in 0.05 M Tris buffer, pH 7.4, at 4 for 16 hours followed by 20-minute incubation at room temperature with super enhancer (Super Sensitive™ Non-Biotin Detection System, [BioGenex, San Ramon, Calif.]), and another 30-minute incubation with polymer-HRP (Super Sensitive™) label. Immunostaining was finally developed with DAB (3-3′ diaminobenzidine tetrahydrochloride). After quenching the enzyme reaction, slides were incubated in DS-enhancer (Zymed, San Francisco, Calif.) at room temperature for five minutes to prevent the interaction between two staining system. Then, slides were incubated in CD34, vimentin, CD68 or α-SMA antibody for one hour at room temperature. After washing, slides were incubated with anti-mouse alkaline phosphatase for 30 minutes at room temperature. BCIP/NBT solution was used for visualisation of the bound antibody. Sections were counterstained with methyl green solution. 
       3. Immunocytochemistry Analysis 
       [0044]    On average 1×10 6  cells were centrifuged at 700 rpm for 3 minutes at room temperature (Kubota 5200, Japan), and the cell was adhered on the poly-L-lysine-coated slides. Before staining, the cytospots were fixed with 3.7% paraformaldehyde for 15 minutes and treated with 0.2% Triton X-100 for 90 seconds. Endogenous peroxidase was blocked with 3% hydrogen peroxide followed by bovine serum albumin blocking for 10 minutes. The slides were incubated with anti-PDPK FA/GSK-3α antibody (2 μg/mL) diluted in 0.05 M Tris buffer, pH 7.4, at 4 for 16 hours followed by 20-minute incubation at room temperature with super enhancer (Super Sensitive™ Non-Biotin Detection System, [BioGenex, San Ramon, Calif.]), and another 30-minute incubation with polymer-HRP (Super Sensitive™) label. Immunostaining was finally developed with DAB (3-3′ diaminobenzidine tetrahydrochloride). After quenching the enzyme reaction, slides were incubated in DS-enhancer (Zymed, San Francisco, Calif.) at room temperature for five minutes to prevent the interaction between two staining system. Then, slides were incubated with CD34, vimentin, CD68 or α-SMA antibody for one hour at room temperature. After washing, slides were incubated with anti-mouse alkaline phosphatase for 30 minutes at room temperature. BCIP/NBT solution was used for visualization of the bound antibody. Sections were counterstained with methyl green solution. 
       4. Method for Detecting Unhealthy BMC/Lethal Cell 
       [0045]    A method for detecting unhealthy BMC/lethal cell in subject, which includes obtaining a biological sample from the subject and analyzing the PDPK F A /GSK-3α expression level in BMC of the sample, wherein the aberrant accumulation of the PDPK F A /GSK-3α in BMC represents the presence of unhealthy BMC in the subject. 
         [0046]    The expression of PDPK F A /GSK-3α is determined by assaying PDPK F A /GSK-3α protein levels such as an immunoassay using antibodies specific for PDPK F A /GSK 3α. The expression can be determined by assessing activity, protein, RNA or DNA level. The biological sample could be bone marrow, cord blood, peripheral blood, tissue sample, ascites, pleural effusion or body fluid. 
       [Result] 
       [0047]    In order to detect the unhealthy BMC in a subject, obtaining a biological sample from the subject and analyzing the PDPK F A /GSK-3α expression level in BMC of the sample, wherein aberrant accumulation of PDPK F A /GSK-3α expression represents the presence of unhealthy BMC in the subject. 
         [0048]    To establish the systemic role of PDPK FA/GSK-3α in bone marrow cell (BMC), an independent cohort study on bone marrow of 24 leukemia patients was performed. In a cohort study of 24 cases, 14 cases were negative and 10 cases were found to be associated with aberrant expressions of PDPK FA/GSK-3α. The immunophenotyping analysis of CD34 further revealed that a rare population of CD34+ hematopoietic stem/progenitor cells, CD34− mesenchymal stem/progenitor cells (Moioli et al, PLoS ONE, 2008, 3:e3922) associated with very strong expressions (&gt;3+) of PDPK FA/GSK-3α, and their derivatives associated with moderate to strong expressions (2+ to 3+) of PDPK FA/GSK-3α ( FIG. 1B ) in contrast to the negative cases ( FIG. 1A ) could be frequently detected in bone marrow of those patients with progressive diseases. 
         [0049]    Immunophenotyping analysis of CD34, CD68, vimentin and α-smooth muscle actin (α-SMA) further revealed that a rare population of CD34+/vimentin− hematopoietic stem/progenitor cells, CD34+/vimentin+ fibrocytes, and CD34−/vimentin+ mesenchymal stem/progenitor cells (Bucala, Fibrocytes, World Scientific Pub Co Inc, 2007:1-18; Moioli et al, PLoS ONE, 2008, 3:e3922) associated with very strong expressions (&gt;3+) of PDPK FA/GSK-3α( FIGS. 2A  and C) within the stromas of incurable stage I tumors with poor prognosis even after curative resections. As described in Example I, along with a relatively large population of CD68+ macrophages ( FIG. 2E ), vimentin+ fibroblasts and mesenchymal cells ( FIG. 2C ) and α-SMA+ myofibroblasts ( FIG. 2G ) associated with moderate to strong expressions (2+ to 3+) of PDPK FA/GSK-3α in contrast to the negative cases with good outcome (see  FIGS. 2B , D, F and H) could be detected predominantly. 
         [0050]    Furthermore, CD34+ fibrocyte-like cell associated with strong expression of PDPK FA/GSK-3α could be detected in peripheral blood of all the tested 3 children from 3 different families suffering from repeated cycles of inflammation ( FIG. 3A  and  FIG. 3B ). The unhealthy BDMC can be detected in cord blood from systematic unhealthy children who were suffered from Kawasaki syndrome (the symptom is immune system disorders) ( FIG. 4 ). 
         [0051]    In a cohort study of 367 stage I tumor cases (including all stage of bladder cancer, breast cancer, brain cancer, bile duct cancer, cervical cancer, colon cancer, endometrial cancer, esophageal cancer, stomach cancer, liver cancer, lung cancer, nasopharyngeal carcinoma, oral cancer, ovary cancer, pancreatic cancer, prostate cancer, kidney cancer, leukemia and lymphoma), 240 cases were negative, and 127 cases were related to PDPK F A /GSK-3α abnormal expression. 
         [0052]    In order to detect the lethal cell in a subject, obtaining a biological sample from the subject and analyzing the PDPK F A /GSK-3α expression in BMDSC of the sample, wherein aberrant accumulation of PDPK F A /GSK-3α expression in BMDSC represents the presence of lethal cell in the subject. 
         [0053]    In a cohort study of 1948 tumor cases (including all stage of bladder cancer, breast cancer, brain cancer, bile duct cancer, cervical cancer, colon cancer, endometrial cancer, esophageal cancer, stomach cancer, liver cancer, lung cancer, nasopharyngeal carcinoma, oral cancer, ovary cancer, pancreatic cancer, prostate cancer, kidney cancer, leukemia and lymphoma), 1098 cases were negative of lethal cell, and 850 cases were related to PDPK F A /GSK-3α aberrant accumulation lethal cell ( FIG. 5 ). When a patient has abnormal expression of signal molecules in the tumor matrix, he/she is more likely to have worse prognosis ( FIG. 6 ). 
         [0054]    Before and after using OPC, the PDPK F A /GSK-3α expression conditions in patients were analyzed by immunochemistry. Analyzing the following samples: acute leukemia (before OPC:  FIG. 7A , after OPC:  FIG. 7B ), lymphoma (before OPC:  FIG. 8A , after OPC:  FIG. 8B ), kidney cancer (before OPC:  FIG. 9A , after OPC:  FIG. 9B ), uterine sarcoma (before OPC:  FIG. 10A , after OPC:  FIG. 10B ) and children with systematic unhealthy from cancer family (before OPC:  FIG. 11A , after OPC:  FIG. 11B ), the result indicates that the samples of patients show PDPK F A /GSK-3α positive result (red-brown) before using OPC, and that the samples of patients show PDPK F A /GSK-3α negative result after using OPC. 
         [0055]    In terms of the above, the present invention provides methods of cancer prevention, disease predisposition prevention, metastasis prevention and vicious cycle prevention by OPC induced PDPK F A /GSK-3α inhibition.
