Dissecting the molecular mechanisms that impair stress granule formation in aging cells

551 views | Jul 04 2018

Moujaber O et al. demonstrated that the loss of CReP correlated with the aging-related hyperphosphorylation of eIF2α. Together, we have identified significant changes in the stress response of aging cells and provide mechanistic insights. Based on our work, we propose that the decline in SG formation can provide a new biomarker to evaluate cellular aging. [Read the Full Post]

PTEN activation through K163 acetylation by inhibiting HDAC6 contributes to tumour inhibition

0 views | Jul 03 2018

Meng Z, et al. indicated that PTEN activation by inhibiting HDAC6 significantly contributed to tumour inhibition. Therefore, non-selective HDAC or HDAC6-specific inhibitors may be more clinically suitable to treat tumours without PTEN mutations or deletions. [Read the Full Post]

Nesfatin-1 protects dopaminergic neurons against MPP+/MPTP-induced neurotoxicity through the C-Raf-ERK1/2-dependent anti-apoptotic pathway

0 views | Jul 02 2018

Shen XL et al. suggested that C-Raf-ERK1/2, which is involved in an anti-apoptotic pathway, is responsible for the neuroprotective effects of nesfatin-1 in the context of MPTP-induced toxicity. These results imply that nesfatin-1 might have therapeutic potential for PD. [Read the Full Post]

LTR12 promoter activation in a broad range of human tumor cells by HDAC inhibition

617 views | Jun 28 2018

Krönung SK et al. showed that inhibition of HDAC1-3 is sufficient for LTR12 activation. Importantly, HDAC inhibitors induce LTR12 activity not only in testicular cancer cells, but also in cells derived from many additional tumor species. Finally, we characterize the transcription factor NF-Y as a mediator of LTR12 promoter activity and HDAC inhibitor-induced apoptosis, in the context of widespread genomic binding of NF-Y to specific LTR12 sequences. Thus, HDAC inhibitor-driven LTR12 activation represents a generally applicable means to induce proapoptotic genes in human cancer cells. [Read the Full Post]
