Clinical Outcomes and Sustainability of Using Genotype-Guided Antiplatelet Therapy After Percutaneous Coronary Intervention.

Background: loss-of-function (LOF) alleles impair clopidogrel effectiveness after percutaneous coronary intervention. The feasibility, sustainability, and clinical impact of using genotype-guided dual antiplatelet therapy (DAPT) selection in practice remains unclear.

Methods: A single-center observational study was conducted in 1193 patients who underwent percutaneous coronary intervention and received DAPT after implementation of an algorithm that recommends testing in high-risk patients and alternative DAPT (prasugrel or ticagrelor) in LOF allele carriers.

Dally and Notum regulate the switch between low and high level Hedgehog pathway signalling.

During development, secreted morphogens, such as Hedgehog (Hh), control cell fate and proliferation. Precise sensing of morphogen levels and dynamic cellular responses are required for morphogen-directed morphogenesis, yet the molecular mechanisms responsible are poorly understood. Several recent studies have suggested the involvement of a multi-protein Hh reception complex, and have hinted at an understated complexity in Hh sensing at the cell surface.

A genome-wide RNAi screen identifies regulators of cholesterol-modified hedgehog secretion in Drosophila.

Hedgehog (Hh) proteins are secreted molecules that function as organizers in animal development. In addition to being palmitoylated, Hh is the only metazoan protein known to possess a covalently-linked cholesterol moiety. The absence of either modification severely disrupts the organization of numerous tissues during development.

Melanin-concentrating hormone induces neurite outgrowth in human neuroblastoma SH-SY5Y cells through p53 and MAPKinase signaling pathways.

Melanin-concentrating hormone (MCH) peptide plays a major role in energy homeostasis regulation. Little is known about cellular functions engaged by endogenous MCH receptor (MCH-R1). Here, MCH-R1 mRNA and cognate protein were found expressed in human neuroblastoma SH-SY5Y cells.

Phosphorylation of the atypical kinesin Costal2 by the kinase Fused induces the partial disassembly of the Smoothened-Fused-Costal2-Cubitus interruptus complex in Hedgehog signalling.

The Hedgehog (Hh) family of secreted proteins is involved both in developmental and tumorigenic processes. Although many members of this important pathway are known, the mechanism of Hh signal transduction is still poorly understood. In this study, we analyse the regulation of the kinesin-like protein Costal2 (Cos2) by Hh.
