IL27 controls skin tumorigenesis via accumulation of ETAR-positive CD11b cells in the pre-malignant skin

247 views | Dec 31 2018

Dibra D et al. indicated that these findings are clinically relevant, as the number of IL27RA-positive cells in the stroma is highly related to tumor de-differentiation in patients with squamous cell carcinomas. [Read the Full Post]

411 views | Dec 31 2018

Gherardi S et al. suggested therefore that Menin could take an important part to the Ezh2-epigenetic repressive landscape in many cells and tissues through its capacity to modulate Akt phosphorylation. [Read the Full Post]

The thrombopoietin/MPL axis is activated in the Gata1low mouse model of myelofibrosis and is associated with a defective RPS14 signature

806 views | Dec 30 2018

Zingariello M et al. showed that Gata1low mice are a bona fide model of MF, which recapitulates the hyperactivation of the TPO/MPL/JAK2 axis observed in megakaryocytes from myelofibrotic patients. [Read the Full Post]

Adipocyte-specific CD1d-deficiency mitigates diet-induced obesity and insulin resistance in mice

0 views | Dec 30 2018

Satoh M et al. indicated that interactions between NKT cells and CD1d-expressing adipocytes producing endogenous NKT cell ligands play a critical role in the induction of inflammation and functional modulation of adipose tissue that leads to obesity. [Read the Full Post]

Tracking gastrointestinal transit of solids in aged rats as pharmacological models of chronic dysmotility

0 views | Dec 28 2018

Dalziel JE et al. demonstrated that loperamide slowed overall transit in aged rats, while prucalopride increased stomach emptying and accelerates colonic transit. [Read the Full Post]

Procaine Attenuates Pain Behaviors of Neuropathic Pain Model Rats Possibly via Inhibiting JAK2/STAT3

0 views | Dec 28 2018

Li D et al. indicated that procaine is capable of attenuating NPP, suggesting procaine is a potential therapeutic strategy for treating NPP. Its role may be associated with the inhibition on JAK2/STAT3 signaling. [Read the Full Post]

PPARβ/δ, a Novel Regulator for Vascular Smooth Muscle Cells Phenotypic Modulation and Vascular Remodeling after Subarachnoid Hemorrhage in Rats

668 views | Dec 27 2018

Zhang H et al. identified PPARβ/δ as a useful regulator for VSMC phenotypic switch and vascular remodeling following SAH, providing novel insights into the therapeutic strategies of delayed cerebral ischemia. [Read the Full Post]

Enhanced efficacy of 5-fluorouracil in combination with a dual histone deacetylase and phosphatidylinositide 3-kinase inhibitor (CUDC-907) in colorectal cancer cells

656 views | Dec 26 2018

Hamam R et al. revealed, for the first time, the enhanced inhibitory effect of CUDC-907 against CRC cells when combined with 5-FU, supporting the application of this combination as a potential therapeutic strategy in CRC treatment. [Read the Full Post]

CUDC-907 Promotes Bone Marrow Adipocytic Differentiation Through Inhibition of Histone Deacetylase and Regulation of Cell Cycle

689 views | Dec 26 2018

Ali D et al. revealed that HDAC, PI3K, and cell cycle genes are important regulators of BMA formation and demonstrate that adipocyte differentiation of hBMSCs is associated with complex changes in a number of epigenetic and genetic pathways, which can be targeted to regulate BMA formation.

Dabigatran reduces thrombin-induced platelet aggregation and activation in a dose-dependent manner

0 views | Dec 25 2018

Vinholt PJ et al. indicated that dabigatran exclusively inhibits thrombin-induced platelet activation and aggregation with a dose-dependent response. Platelet stimulation with other agonists was not affected by dabigatran. [Read the Full Post]

Structure-activity relationships of nucleoside analogues for inhibition of tick-borne encephalitis virus

249 views | Dec 25 2018

Eyer L et al. indicated that high antiviral activity and low cytotoxicity of C2' methylated or C4' azido substituted pharmacophores suggest that such compounds might represent promising candidates for further development of potential therapeutic agents in treating TBEV infection. [Read the Full Post]

RNA Polymerase I Inhibition with CX-5461 as a Novel Therapeutic Strategy to Target MYC in Multiple Myeloma

302 views | Dec 24 2018

Lee HC et al. provided a rationale for the clinical translation of CX-5461 as a novel therapeutic approach to target MYC in myeloma. [Read the Full Post]

The antibiotic polymyxin B exhibits novel antifungal activity against Fusarium species

0 views | Dec 23 2018

Hsu LH et al. found that PMB was fungicidal against all 12 Fusarium strains, with minimum fungicidal concentrations of 32 µg/mL or 64 µg/mL for most strains tested, as evidenced by broth dilution, methylene blue staining and XTT reduction assays. PMB can reduce the germination rates of conidia, but not chlamydospores, and can cause defects in cell membrane integrity in Fusarium strains. [Read the Full Post]

WIP1 modulates responsiveness to Sonic Hedgehog signaling in neuronal precursor cells and medulloblastoma

0 views | Dec 23 2018

Wen J et al. found that Wip1 knockdown or treatment with a WIP1 inhibitor suppressed the effects of Shh stimulation and potentiated the growth inhibitory effects of SHH pathway-inhibiting drugs in Shh-activated MB cells in vitro. [Read the Full Post]
