Wnt/b-Catenin-Signaling and the Formation of M€uller Glia-Derived Progenitors in the Chick Retina

1410 views | Feb 04 2017

Gallina D, et al 's findings indicate that Wnt-signaling is part of a network initiated by FGF2/MAPK or retinal damage, and activation of canonical Wnt-signaling is required for the formation of proliferating MGPCs. [Read the Full Post]

The gender differences in the inhibitory action of UVB-induced melanocyte activation by the administration of tranexamic acid.

2176 views | Feb 01 2017

Hiramoto K et al. suggested that the suppression by tranexamic acid of the UVB-induced melanocyte activation (UVB sensitivity) is stronger in female mice than in male mice and that female hormones and β-endorphin play an important role in this sex difference. [Read the Full Post]

Targeting the Neurokinin-1 Receptor Compromises Canonical Wnt Signaling in Hepatoblastoma

1193 views | Jan 31 2017

Ilmer M et al. revealed important insight into the molecular mechanisms of the SP/NK1R complex as a critical component in a model of pediatric liver cancer and may support the development of novel therapeutic interventions for HB and other Wnt-activated cancers. [Read the Full Post]

An RNA interference screen identifies new avenues for nephroprotection

1202 views | Jan 31 2017

These data shed new light on the mechanisms of stress response in mammalian cells, and open new avenues to reduce the morbidity and mortality associated with renal injury. [Read the Full Post]

Reversal of dabigatran effects in models of thrombin generation and hemostasis by factor VIIa and prothrombin complex concentrate

1936 views | Jan 30 2017

The ineffectiveness of FVIIa at supratherapeutic dabigatran levels may explain conflicting reports of its efficacy in dabigatran reversal. [Read the Full Post]

Inhibition of Human UDP-Glucuronosyltransferase Enzymes by Canagliflozin and Dapagliflozin: Implications for Drug-Drug Interactions

1216 views | Jan 29 2017

Pattanawongsa A et al. reported the inhibition of human recombinant UGTs by CNF and DPF, along with the Ki values for selected recombinant and human liver microsomal UGTs. [Read the Full Post]

A repurposing strategy for Hsp90 inhibitors demonstrates their potency against filarial nematodes

3262 views | Jan 29 2017

Understanding the molecular mechanism of host-based statin resistance in hepatitis C virus replicon containing cells

1630 views | Jan 28 2017

Delang L et al. demonstrated that statin resistance in HCV replicon containing hepatoma cells is conferred by changes in the cellular environment. [Read the Full Post]

Delayed Administration of WP1066, an STAT3 Inhibitor, Ameliorates Radiation-Induced Lung Injury in Mice

2487 views | Jan 28 2017

The activation of STAT3 pathway might play an important part in the pathogenesis of radiation-induced lung injury. The protective effects of delayed treatment of WP1066 suggested STAT3 signaling could be a therapeutic target for radiation pneumonitis. [Read the Full Post]

PTEN activation through K163 acetylation by inhibiting HDAC6 contributes to tumour inhibition

2074 views | Jan 27 2017

Meng Z et al. found that non-selective HDAC or HDAC6-specific inhibitors may be more clinically suitable to treat tumours without PTEN mutations or deletions. [Read the Full Post]

GSK-3β inhibitor TWS119 attenuates rtPA-induced hemorrhagic transformation and activates the Wnt/β-catenin signaling pathway after acute ischemic stroke in rats

1290 views | Jan 27 2017

Wang W et al. suggested that TWS119 reduces rtPA-induced HT and attenuates blood-brain barrier disruption, possibly through activation of the Wnt/β-catenin signaling pathway. This study provides a potential therapeutic strategy to prevent tPA-induced HT after acute ischemic stroke. [Read the Full Post]

Overexpression of GAB2 in ovarian cancer cells promotes tumor growth and angiogenesis by upregulating chemokine expression

955 views | Jan 25 2017
