0 views | Dec 18 2018

Park GB et al. showed that characterization of the p110 isotypes of PI3K is critical for regulating cancer metastasis; LIMK1 could be a common therapeutic target of ovarian cancer metastasis. [Read the Full Post]

MicroRNA-24-1 suppresses mouse hepatoma cell invasion and metastasis via directly targeting O-GlcNAc transferase

302 views | Dec 17 2018

Liu Y et al. suggested that as a tumor suppressor, miR-24-1 may regulate mouse hepatocarcinoma cells migration and invasion, at least partially through targeting OGT, which could regulate the O-GlcNAcylation and the stability of this oncoprotein c-Myc. This may give insight into a novel mechanism and therapy of tumor lymphatic metastasis. [Read the Full Post]

SIRT1 prevents hyperuricemia via the PGC-1α/PPARγ-ABCG2 pathway

720 views | Dec 17 2018

Wang J et al. demonstrated that SIRT1 and its activator, RSV, have clear anti-hyperuricemia functions in this mouse model. One possible mechanism is the activation of ABCG2 in the ileum through the PGC-1α/PPARγ pathway. [Read the Full Post]

Microengineered cultures containing human hepatic stellate cells and hepatocytes for drug development

299 views | Dec 16 2018

Davidson MD et al. found that NADPH oxidase (NOX) inhibition and farnesoid X receptor (FXR) activation using clinically relevant drugs alleviated hepatic dysfunctions in MPTCs. In conclusion, MPTCs recapitulate symptoms of NASH- and early fibrosis-like dysfunctions in PHHs and have utility for drug discovery in this space. [Read the Full Post]

Leishmania donovani Aurora kinase: A promising therapeutic target against visceral leishmaniasis

434 views | Dec 15 2018

Chhajer R et al. identified an Aurora kinase homolog in L. donovani implicated in cell-cycle progression, whose inhibition led to aberrant changes in cell-cycle progression and reduced viability. [Read the Full Post]

FAM83A is amplified and promotes cancer stem cell-like traits and chemoresistance in pancreatic cancer

572 views | Dec 15 2018

Chen S et al. indicated that FAM83A has a vital oncogenic role to promote pancreatic cancer progression and may represent a potential clinical target. [Read the Full Post]

PI3Kδ and PI3Kγ isoforms have distinct functions in regulating pro-tumoural signalling in the multiple myeloma microenvironment

274 views | Dec 14 2018

Piddock RE et al. reported that PI3Kδ and PI3Kγ isoforms have distinct functions in MM and that combined PI3kδ/γ isoform inhibition has anti-MM activity. Here we provide a scientific rationale for trials of dual PI3kδ/γ inhibition in patients with MM. [Read the Full Post]

Identification of DNA-PKcs as a primary resistance factor of TIC10 in hepatocellular carcinoma cells

456 views | Dec 14 2018

Cheng L et al. found that TIC10 showed promising anti-HCC activity, alone or together with DNA-PKcs inhibitors. [Read the Full Post]

Heme oxygenase-1 mitigates ferroptosis in renal proximal tubule cells

269 views | Dec 13 2018

Adedoyin O et al. demonstrated an important antiferroptotic role of HO-1 in renal epithelial cells. [Read the Full Post]

Therapeutic targeting of Polo-like kinase-1 and Aurora kinases in T-cell acute lymphoblastic leukemia

Spartà AM et al. indicated that PLK1 and AK inhibitors display the potential for being employed in innovative therapeutic strategies for improving T-ALL patient outcome. [Read the Full Post]

Testosterone improves the differentiation efficiency of insulin-producing cells from human induced pluripotent stem cells

381 views | Dec 12 2018

Liu H et al. found that T improves the differentiation efficiency of insulin-producing cells from hiPSCs. The addition of T into routine differentiation formula for pancreatic β cells increases the differentiation efficiency from 12% to 35%. The administration of T promotes the expression of key genes associated with β cells differentiation including NGN3, NEUROD1 and INS. This finding benefits the ongoing process to optimize the differentiation protocol of pancreatic β cells from hiPSCs, and provides some degree of understanding the clinical management of T for type 2 diabetes.

Yang Y et al. demonstrated that HDAC10 localizes and functions in the cytoplasm of lung cancer cells, thereby underscoring its potential role in the diagnosis and treatment of lung cancer. [Read the Full Post]

5-HT4 receptors facilitate cholinergic neurotransmission throughout the murine gastrointestinal tract

632 views | Dec 11 2018

Pauwelyn V et al. showed that in the murine gastrointestinal tract, activation of 5-HT4 receptors with prucalopride enhances cholinergic contractions, illustrating facilitation of myenteric cholinergic neurotransmission. The degree of enhancement with prucalopride is of similar magnitude as previously reported in other species, but the effective concentrations are lower than those needed in the gastrointestinal tract of other species.
