Epigenetic drug combination induces remission in mouse xenograft models of pediatric acute myeloid leukemia

490 views | Nov 18 2018

Gopalakrishnapillai A et al. indicated the expression of mutant p53 in MV4;11 cells reduced sensitivity to azacitidine-panobinostat combination, suggesting that p53 may be a predictor of response to epigenetic therapy in pediatric AML. [Read the Full Post]

Circadian rhythm disruption impairs tissue homeostasis and exacerbates chronic inflammation in the intestine

307 views | Nov 18 2018

Pagel R et al. suggested that circadian rhythm stability is pivotal for the maintenance of mucosal barrier function. CRD increases intestinal necroptosis, thus rendering the gut epithelium more susceptible to inflammatory processes.-Pagel, R., Bär, F., Schröder, T., Sünderhauf, A., Künstner, A., Ibrahim, S. M., Autenrieth, S. E., Kalies, K., König, P., Tsang, A. H., Bettenworth, D., Divanovic, S., Lehnert, H., Fellermann, K., Oster, H., Derer, S., Sina, C. Circadian rhythm disruption impairs tissue homeostasis and exacerbates chronic inflammation in the intestine. [Read the Full Post]

Oncogenic KRas-induced Increase in Fluid-phase Endocytosis is Dependent on N-WASP and is Required for the Formation of Pancreatic Preneoplastic Lesions
