In the mammalian neocortex, the calcium-binding protein calretinin is expressed in a subset of cortical interneurons. In the recent years, research on interneurons is one of the most rapidly growing fields in neuroscience. This review summarizes the actual knowledge of the functions of calretinin in neuronal homeostasis and particularly of the distribution, connectivity and physiological properties of calretinin expressing interneurons in the neocortex of rodents and primates, including humans. The possible neuroprotective role of calretinin and the presumed “resistance” of calretinin-expressing interneurons to various pathological processes are also discussed.

Chick Chorioallantoic Membrane

The preparation of a specific antiserum (anti-CaBP) against the calcium-binding protein (CaBP) of the chorioallantoic membrane (CAM) is described. The anti-CaBP appeared to be specific for the CaBP by immunodiffusion and immunoelectrophoresis. Application of the anti-CaBP in immunofluorescence histochemistry revealed that the CaBP is present in the CAM only at developmental ages corresponding with the expression of the calcium transport function of the membrane. Furthermore, the CaBP is localized to the ectoderm of the CAM, appears to be exposed to the entire external surface of the ectoderm, and can be shown to be associated with cells enzymatically dissociated from the CAM. These results are consistent with a functional role of the CaBP in the CAM calcium transport process.

Abstract Introduction: S100 Calcium Binding Protein A12 (S100A12) is a member of the S100 protein family and is widely expressed in neutrophil and low expressed in lymphocytes and monocyte. However, the role of S100A12 in glioma has not yet been identified. Methods: In the present study, we carried out immunohistochemical investigation of S100A12 in 81 glioma tissues to determine the expression of s100A12 in glioma cells, and evaluate the clinical significance of S100A12 in glioma patients. Futher we knockdown the S100A12 by ShRNA, and evaluated cell proliferation, cell migration and cell apoptosis by MTT,clony formation assay, transwell assay ,flow cytometry assa and westernblot. Results: We found that S100A12 was upregulated in tissues of glioma patients and the expression was correlated to WHO stage and tumor size. Further, we found that knockdown S100A12 inhibits the proliferation, migration and invasion of glioma cells through regulating cell apoptosis and EMT. Conclusions: These findings demonstrated a novel function for S100A12 in glioma progression and suggested that S100A12 may be served as a new marker in the tumorigenesis and progression of glioma.

Abstract Background: Neutrophilic inflammation is a predominant characteristic of idiopathic pulmonary fibrosis (IPF). S100 Calcium-Binding Protein A9 (S100A9) is a neutrophil-derived protein and is involved in the development of neutrophil-related chronic inflammatory disorders. However, the role of S100A9 in IPF has not been evaluated.Methods : S100A9 concentrations were measured by ELISA in the BAL fluid obtained from NCs (n = 33) and patients with IPF (n = 87), NSIP (n = 22), HP (n = 19), or sarcoidosis (n = 10).Results: The S100A9 levels in BALF were significantly higher in patients with IPF than in those with NC (0.4 [0.18–0.9] vs. 0 [0–0.5] ng/mL, p < 0.001), HP (0.19 [0.07–0.33] ng/mL, p = 0.043), or sarcoidosis (0.06 [0–0.11] ng/mL, p < 0.001) patients. A S100A9 level of 0.093 ng/mL had discriminating powers of 78.79% for specificity and 81.61% for sensitivity between IPF patients and NCs. S100A9 levels were also correlated with neutrophil numbers (r = 0.356, p = 0.0007) and S100A9 was expressed on neutrophils and macrophages in the BALF of IPF patients. Patients with S100A9 levels above 0.5535 ng/mL or a neutrophil percentage above 49.09% (n = 43) had significantly lower survival rates than those with S100A9 levels at or below 0.5535 ng/mL and a neutrophil percentage at or below 49.09% (n = 41) (HR, 9.28; p = 0.0004).Conclusion: S100A9 may participate in the development and progression of IPF. The levels of S100A9 in BALF may be a surrogate marker for diagnosing IPF and predicting its prognosis.
