Apoptosis, programmed cell death, has a central role in developmental biology and maintaining the equilibrium of renewing tissues. A founding member Bcl-2 family regulatory proteins for apoptosis is Bcl-2, which encoded by BCL2 gene. Caspase-3 shares typical features with all caspases, including acting as crucial mediator apoptosis.

signal regulatory proteins (sirp) belong to immunoglobulin super family (igsf) and relate to integrin signaling cascades. it has been shown that sirpa is expressed in a variety of cells including myeloid cells and neurons. in the present study the expression of this igsf member in articular chondrocytes was investigated. methods: using a panel of anti-sirpalpha antibodies, immunohistochemistry,...

apoptosis or programmed cell death is a gene regulated phenomenon which is important in both physiological and pathological conditions. it is characterized by distinct morphological features including chromatin condensation, cell and nuclear shrinkage, membrane blebbing and oligonucleosomal dna fragmentation. although, two major apoptotic pathways including 1) the death receptor (extrinsic) and...

Aging, as a major risk factor of memory deficiency, affects neural signaling pathways in hippocampus. In particular, age-dependent androgens deficiency causes cognitive impairments. Several enzymes like protein kinase C (PKC) are involved in memory deficiency. Indeed, PKC regulatory process mediates α-secretase activation to cleave APP in β-amyloid cascade and tau proteins phosphorylation mecha...

Spinal cord injury is pathologically characterized by the loss of motor function caused neurons apoptosis. Store-operated calcium entry (SOCE) widely known to dictate apoptosis various cell types. To examine SOCE in spinal and explore role apoptosis, patients with (SCI) SCI mouse models were included. Expression components apoptosis-related proteins examined Western blotting. Calcium imaging wa...

During the past two decades, apoptotic cell death has been the subject of an intense wave of investigation, leading to the discovery of multiple gene products that govern both its induction and execution. In parallel, it has progressively become evident that most, if not all, proteins that had initially been discovered for their essential role in apoptosis also mediate a wide range of non-apopt...

Snake venom, as a natural biotoxin, is widely present in nature and can act coordination with variety of signal regulatory proteins, playing significant role the regulation tumor cell proliferation, metastasis, invasion, angiogenesis. Malignant tumors have long attracted attention medical community leading cause death humans. In this paper, we focus on reviewing progress snake venom apoptosis, ...

Abstract Objective: To investigate the involvement of HOX transcript antisense RNA (HOTAIR) in injury renal tubular epithelial cells induced by high glucose. Results: In glucose‐induced HK‐2 cells, expression HOTAIR was upregulated, resulting suppressed cell proliferation. Meanwhile, upregulates pro‐apoptotic proteins Bax and cleaved caspase‐3, while downregulating anti‐apoptotic protein Bcl‐2....
