Macrophages accumulate in poorly vascularised and hypoxic sites including solid tumours, wounds and sites of infection and inflammation where they can be exposed to low levels of oxygen for long periods. Up to date, different studies have shown that a number of transcription factors are activated by hypoxia which in turn activate a broad array of mitogenic, pro-invasive, pro-angiogenic, and pro...

Several lines of evidence suggest that some neurotoxicity in AD is due to proteolytic fragments of APP. In this study, we compared the potency of neurotoxicity induced by CT with that of A-beta neurotoxicity and our results showed that various CT peptide fragments (CTFs; CTF99, AICD, CTF31) caused neurotoxicity in cultured cells and primary cortical neurons, induced strong non-selective inward ...

Objective(s): The Janus kinase-signal transducers and activators of transcription signaling pathway (JAK/STAT pathway) play an important role in proliferation of breast cancer cells. Previous data showed that inhibition of STAT3 suppresses the growth of breast cancer cells, but the associated mechanisms are not well understood. This study aims to investigate the effect and associated mechanisms...

Manipulation of stress related transcription factors to improve plant stress tolerance is a major goal of current biotechnology researches. MYC2 gene encodes a key stress-related transcription factor involved in Jasmonate (JA) and abscisic acid (ABA) signaling pathways in Arabidopsis. Brassica napus, as a globally important oilseed crop, is a close relative of Arabidopsis.  In the present study...

a:4:{s:10:"Background";s:1707:"Early embryonic development in mammals begins in transcriptional silence with an oocyte-mediated transcriptional reprogramming of parental gametes occurs during a so called across-the-board process of “erase-and-rebuild”. In this process, the parental transcription programs are erased long before (maternal) or soon thereafter (paternal) fertilization to generate a...
