[EX Q]: A growing body of evidence indicates a positive correlation between expression of human antimicrobial peptide leucin leucin 37 (LL-37) and progression of epithelial cancers, including prostate cancer (PCa). Although the molecular mechanisms for this correlation has not yet been elucidated, the primary function of LL-37 as a chemotactic molecule for innate immune effector cells suggests its possible association in coordinating protumorigenic mechanisms, mediated by tumor-infiltrating immune cells.', 'To investigate protumorigenic role(s) of cathelicidin-related antimicrobial peptide (CRAMP), a murine orthologue of LL-37, the present study compared tumor growth kinetics between mouse PCa cell lines with and without CRAMP expression (TRAMP-C1 and TRAMP-C1(CRAMP-sh) , respectively) in immunocompetent mice. CRAMP-mediated chemotaxis of different innate immune cell types to the tumor microenvironment (TME) was observed in vivo and confirmed by in vitro chemotaxis assay. The role of CRAMP in differentiation and polarization of immature myeloid progenitors (IMPs) to protumorigenic type 2 macrophages (M2) in TME was determined by adoptive transfer of IMPs into mice bearing CRAMP(+) and CRAMP(-) tumors. To differentiate protumorigenic events mediated by tumor-derived CRAMP from host immune cell-derived CRAMP, tumor challenge study was performed in CRAMP-deficient mice. To identify mechanisms of CRAMP function, macrophage colony stimulating factor (M-CSF) and monocyte chemoattractant protein 1 (MCP-1) gene expression was analyzed by QRT-PCR and STAT3 signaling was determined by immunoblotting.', 'Significantly delayed tumor growth was observed in wild-type (WT) mice implanted with TRAMP-C1(CRAMP-sh) cells compared to mice implanted with TRAMP-C1 cells. CRAMP(+) TME induced increased number of IMP differentiation into protumorigenic M2 macrophages compared to CRAMP(-) TME, indicating tumor-derived CRAMP facilitates differentiation and polarization of IMPs toward M2. Tumor challenge study in CRAMP deficient mice showed comparable tumor growth kinetics with WT mice, suggesting tumor-derived CRAMP plays a crucial role in PCa progression. In vitro study demonstrated that overexpressed M-CSF and MCP-1 in TRAMP-C1 cells through CRAMP-mediated autocrine signaling, involving p65, regulates IMP-to-M2 differentiation/polarization through STAT3 activation.

[EX Q]: We examined hypoxia-inducible protein 2, hypoxia-inducible factor-1alpha and nuclear factor-kappaB in acquired cystic disease of the kidney associated with renal cell carcinoma to elucidate the roles of these factors in cyst formation and subsequent tumor transformation.', 'Immunohistochemical expression of hypoxia-inducible protein 2, hypoxia-inducible factor-1alpha and phosphorylated nuclear factor-kappaB (active form) were examined in 20 normal kidney samples obtained from nephrectomy for localized renal cell carcinoma and 25 kidneys with acquired cystic disease associated renal cell carcinoma from 23 patients on dialysis.', 'Only faint or weak immunostaining for hypoxia-inducible protein 2, hypoxia-inducible factor-1alpha and phosphorylated nuclear factor-kappaB was observed in normal kidney tissues. In nontumor areas of the kidneys with acquired cystic disease expressions of these 3 proteins was up-regulated in tubular and cyst epithelial cells. Acquired cysts were classified into 3 types according to cyst epithelium morphology, namely flat, cuboidal and hyperplastic. Hyperplastic cysts were the predominant cysts expressing hypoxia-inducible protein 2 and hypoxia-inducible factor-1alpha. Although up-regulation of hypoxia-inducible protein 2, hypoxia-inducible factor-1alpha and phosphorylated nuclear factor-kappaB was observed in renal cell carcinoma, positive hypoxia-inducible protein 2 immunostaining was detected predominantly in papillary renal cell carcinoma, while positive hypoxia-inducible factor-1alpha and phosphorylated nuclear factor-kappaB immunostaining was prominent in clear cell renal cell carcinoma.

[EX Q]: Carbamazepine is a commonly used anticonvulsant agent; however, it has been linked with various blood cell abnormalities. This study evaluated the effect of low-dose folic acid supplementation on the prevention of carbamazepine-induced hematological derangements in children.', 'This randomized clinical trial was conducted in children with epilepsy who received carbamazepine monotherapy. Group 1 received carbamazepine alone, and group 2 received carbamazepine plus folic acid. The two groups were age- and sex-matched. Each group comprised 41 children with epilepsy. Complete blood counts were obtained before starting medication (baseline) and then serially. The patients were followed for at least 1 year.', 'In group 1, 31.4% of the patients developed leukopenia and 17.1% neutropenia, but in group 2, these figures were 14.6 and 9.8% (P = 0.067 and P = 0.331, respectively). At the end of the first year of follow up, white blood cell and polymorphonuclear cell counts were significantly higher in group 2 (P = 0.007 and P = 0.001, respectively). Hemoglobin concentration dropped in group 1, but rose slightly in group 2; these changes were significant. Platelet, lymphocyte, and monocyte counts and changes in serial blood tests did not differ significantly between the two groups.
