Conversion of Terminally Committed Hepatocytes to Culturable Bipotent Progenitor Cells with Regenerative Capacity

51 views | Aug 03 2019

Katsuda T et al. reported that a cocktail of small molecules, Y-27632, A-83-01, and CHIR99021, can convert rat and mouse MHs in vitro into proliferative bipotent cells, which we term chemically induced liver progenitors (CLiPs). CLiPs can differentiate into both MHs and biliary epithelial cells that can form functional ductal structures. CLiPs in long-term culture did not lose their proliferative capacity or their hepatic differentiation ability, and rat CLiPs were shown to extensively repopulate chronically injured liver tissue. Thus, our study advances the goals of liver regenerative medicine. [Read the Full Post]

Cytotoxicity and activation of the Wnt/beta-catenin pathway in mouse embryonic stem cells treated with four GSK3 inhibitors

0 views | Jul 18 2019

Naujok O et al. indicated that out of the four tested GSK3 inhibitors, only CHIR-99021 and CHIR-98014 proved to be potent pharmacological activators of the Wnt/beta-catenin signaling pathway. But only in the case of CHIR-99021 high potency was combined with very low toxicity. [Read the Full Post]

White light emitting diode induces autophagy in hippocampal neuron cells through GSK-3-mediated GR and RORα pathways

134 views | Apr 03 2019

Yang Y et al. demonstrated that GSK-3-mediated GR/RORα signaling pathway is involved in white LED light-induced autophagy in hippocampal neuron cells. [Read the Full Post]

Ionizing Radiation Blocks Hair Cell Regeneration in Zebrafish Lateral Line Neuromasts by Preventing Wnt Signaling

206 views | Feb 15 2019

Li R et al. suggested that radiation suppressed hair cell regeneration in zebrafish lateral line neuromasts through inhibition of Wnt signaling in supporting cells possibly by secreting anti-proliferation factors like dkk2. Maintaining a healthy supporting cell pool is vital for regeneration of hair cells. [Read the Full Post]

Molecular regulation of apoptotic machinery and lipid metabolism by mTORC1/mTORC2 dual inhibitors in preclinical models of HER2+/PIK3CAmut breast cancer

205 views | Jan 30 2019

Qian J et al. found that the basal levels of carnitine palmitoyltransferase 1A and lipid catabolism were elevated in HER2+/PIK3CAmut breast cells and were inhibited upon mTOR-KI treatment. [Read the Full Post]

Integrated High Throughput Analysis Identifies GSK3 as a Crucial Determinant of p53-Mediated Apoptosis in Lung Cancer Cells

232 views | Dec 03 2018

Zhang Y et al. provided us with new insights regarding the mechanism by which p53 mediates A549 apoptosis and may cast light on the development of more efficient p53-based strategies for treating lung cancer. [Read the Full Post]

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]

Dual inhibition of Bcl-2 and Bcl-xL strikingly enhances PI3K inhibition-induced apoptosis in human myeloid leukemia cells through a GSK3- and Bim-dependent mechanism

419 views | Sep 23 2018

Rahmani M et al. argued that combining PI3K/AKT/mTOR inhibitors with BH3 mimetics warrants attention in AML, particularly in the setting of basal AKT activation and/or addiction. [Read the Full Post]

Adenovirus-mediated TIPE2 overexpression inhibits gastric cancer metastasis via reversal of epithelial-mesenchymal transition

635 views | Jun 25 2018

Yin H et al. provided the first evidence that TIPE2 inhibits gastric cancer cell migration, invasion and metastasis very probably via reversal of EMT, revealing that TIPE2 may be a novel therapeutic target for human gastric cancer EMT and metastasis. [Read the Full Post]

FGF19 promotes epithelial-mesenchymal transition in hepatocellular carcinoma cells by modulating the GSK3β/β- catenin signaling cascade via FGFR4 activation

1531 views | May 03 2018

Zhao H et al. indicated that FGFR4/GSK3β/β-catenin axis may play a pivotal role in FGF19-induced EMT in HCC cells. As FGF19 and its specific receptor FGFR4 are frequently amplified in HCC cells, selective targeting this signaling node may lend insights into a potential effective therapeutic approach for blocking metastasis of HCC.
