Novel role of STRAP in progression and metastasis of colorectal cancer through Wnt/β-catenin signaling

0 views | Oct 06 2018

Yuan G et al. suggest that STRAP increases invasion and metastasis of CRC partly through inhibiting ubiquitin-dependent degradation of β-catenin and promoting Wnt/β-catenin signaling. [Read the Full Post]

Modification of tumour cell metabolism modulates sensitivity to Chk1 inhibitor-induced DNA damage

710 views | Oct 05 2018

Massey AJ suggested the expression and activation of Chk1 kinase is associated with cells undergoing active DNA replication. Glutamine starvation rendered tumour cells more resistant to Chk1 inhibitor-induced DNA damage and reversal of the glutamine starvation restored the sensitivity of tumour cells to Chk1 inhibitor-induced DNA damage. Chk1 inhibitors may be a potentially useful therapeutic treatment for patients whose tumours contain a high fraction of replicating cells. [Read the Full Post]

AT-101 inhibits hedgehog pathway activity and cancer growth

0 views | Oct 02 2018

Wang J et al. revealed a novel molecular mechanism responsible for the anticancer action of AT-101 and contributes to the further development of AT-101 as an anticancer drug. [Read the Full Post]

TP53 mutated glioblastoma stem-like cell cultures are sensitive to dual mTORC1/2 inhibition while resistance in TP53 wild type cultures can be overcome by combined inhibition of mTORC1/2 and Bcl-2

521 views | Oct 02 2018

Venkatesan S et al. suggested that Bcl-2 confers resistance to mTORC1/2 inhibitors in TP53 wild type GSCs and that combined inhibition of both mTORC1/2 and Bcl-2 is worthwhile to explore further in TP53 wild type glioblastomas, whereas in TP53 mutated glioblastomas dual mTORC1/2 inhibitors should be explored.

Experimental observation of human bone marrow mesenchymal stem cell transplantation into rabbit intervertebral discs

1272 views | Sep 30 2018

Tao H et al. indicated that in the sections of specimens removed at 1, 2, 4, 6 and 8 weeks post-transplantation, no GFP-positive cells were observed in the control groups, whereas GFP-positive cells were apparent in the nucleus pulposus at all periods in the GFP-labeled human BMSCs group, and the cell density at 6 and 8 weeks was significantly less than that at 1, 2 and 4 weeks post-transplantation (P<0.001).
