[Q]: Context: Hyaluronic acid binding protein 1 (HABP1), a family of proteins interacting with hyaluronan (HA), had been associated with cell adhesion and tumor invasion. The aim of this study was to investigate the correlation between clinicopathologic factors and patient survival time with the expression of HABP1 in breast cancer patients.', 'Expression of HABP1 mRNA and protein were detected with real-time quantitative PCR and immunohistochemical staining in 63 breast cancer and non-cancerous matched tissues.', "The mRNA expression level of HABP1 was unrelated to the patient's age, tumor size, histological grade, TNM stage. However, it proved to be positively related to axillary nodes metastasis (P = 0.008). Furthermore, it was shown that the survival rate of patients with low HABP1 expression was significantly higher than that of patients with high HABP1 expression (P = 0.025). Multivariate analysis revealed that HABP1 mRNA expression level was a significant factor for predicting prognosis (P = 0.022). The immunohistochemistry results showed that the expression level of HABP1 in breast cancer cells was higher than that in normal breast cells.
Answer: HABP1 might be an independent predictive factor for breast cancer prognosis and up-regulation of HABP1 might play an important role in the metastasis of breast cancer.

[Q]: Context: Autoimmune hepatitis type 2 (AIH-2), a severe juvenile liver disorder of unknown etiology and pathogenesis, is characterized by liver-kidney microsomal antibody type 1 targeting cytochrome P450IID6 (CYP2D6) and is associated to HLA DRB1*07. Although CYP2D6 B-cell reactivity has been extensively characterized, little is known about CYP2D6-specific T-cell responses. The aim of the present study was to characterize anti-CYP2D6 cellular immune responses and their possible pathogenic role in patients with AIH-2.', 'We investigated T-cell reactivity against 61 overlapping peptides spanning the full CYP2D6 protein using ex vivo cultures obtained at diagnosis, remission, and relapse. Moreover, CYP2D6-specific T-cell reactivity was investigated in the context of HLA restriction, peptide-binding affinity to HLA DRB1*07, cytokine profile, disease specificity, and clinical course.', 'Proliferative responses to CYP2D6 cluster to 7 antigenic regions in DRB1*07 and to 4 regions in non-DRB1*07 patients. Whereas distinct peptides induce production of interferon gamma, interleukin-4, or interleukin-10, peptides inducing interferon-gamma and proliferation overlap. There is also an overlap between sequences inducing T- and B-cell responses. The breadth (number of epitopes) and intensity (quantity of cytokine produced) of the T-cell response are directly correlated to disease activity (biochemical and histologic markers).
Answer: These data imply that the T-cell response to CYP2D6 in AIH-2 is polyclonal, involves multiple effector types targeting different epitopes, and is associated with hepatocyte damage, knowledge that should form the basis for a more refined therapeutic approach.

[Q]: Context: Simvastatin has lung vascular-protective effects via augmentation of endothelial barrier function. Accordingly, on the basis of our previous study, we hypothesized that endothelial cell (EC) protection by simvastatin is dependent on the stabilization on cytoskeletons.', 'Sixty C57BL/6 mice were divided into two experimental groups: LPS group (L group) and LPS+simvastatin treated group (L+S group). All mice in these two groups received an intraperitoneal injection of LPS (10\u200amg/kg/d). Simvastatin was administered intraperitoneally immediately after the LPS injection in animals of the L+S group at a dose of 20\u200amg/kg/day. Lung injury degree and the protective effects of simvastatin against LPS-induced lung injury were assessed at the time-points of 24, 48 and 72\u200ah post-injection. Serum alanine transaminase (ALT), serum creatinine (Scr) were identified to assess the hepatic and renal side-effects of simvastatin.', 'LPS inhibited the cytoskeletal regulating proteins of Cdc42 and PAK4, and was accompanied by an increased circulating endothelial microparticles (EMPs) level. The adherent junction (AJ) protein of VE-cadherin was also decreased by LPS, and was accompanied by a thickening alveolar wall, increased lung W/D values and high albumin concentration in bronchoalveolar lavage (BAL). Protective effects of simvastatin against LPS-induced lung injury were illustrated by regulating and stabilizing cytoskeletons, as well as intercellular AJs. The values of ALT and Scr were all lower than the common upper limits according to assay kits.
Answer: An increased serous EMP level associated with Cdc42-PAK4 can be deemed as a useful pulmonary injury marker in LPS-treated mice, and our results might be more relevant in guiding the clinical treatment of ALI by intervening Cdc42-PAK4 or EMPs.
