GPR35 mediates lodoxamide ‐induced migration inhibitory response but not CXCL17‐induced migration stimulatory response in THP‐1 cells; Is GPR35 a receptor for CXCL17?
Abstract GPR35 has long been considered an orphan G protein‐couple receptor, and although no endogenous ligand of GPR35 has been discovered, synthetic agonists and antagonists have been developed. CXCL17 (a chemokine) has been reported to be an endogenous ligand of GPR35, and it has even been suggested that it be called CXCR8 (Journal of Immunology 2015; 194:29‐33). However, no supporting report on the CXCL17‐GPR35 relation has been issued since, although GPR35 is supposed to be a potential therapeutic target in several pathologic conditions. In the present study, we applied two assay systems to explore the relations...

Abstract B04: RAD51 expression as a biomarker of homologous recombination deficiency in ovarian cancer
RAD51 is a critical component of the homologous recombination pathway, forming a nucleoprotein filament that enables strand exchange and templated error-free DNA repair. The tumor suppressors BRCA1 and BRCA2 interact with RAD51 to control its activity on DNA. Defects in homologous recombination in tumors are clinically relevant, with evidence of synthetic lethality of such cancers to poly ADP ribose polymerase (PARP) inhibitors.Mutations in RAD51 are uncommon in cancer, but aberrant over-expression of RAD51 has been reported as a mechanism to overcome a recombination defect in in-vitro models. However there are no large sc...

G α12 Facilitates Carbachol‐Induced Shortening in Human Airway Smooth Muscle By Modulating Phosphoinositide 3‐Kinase‐Mediated Activation In A RhoA‐Dependent Manner
CONCLUSION AND IMPLICATIONSGα12 plays a crucial role in HASMC contraction via RhoA‐dependent activation of the PI3K/ROCK axis. Inhibition of RhoA activation induces bronchodilation in hPCLS, and targeting Gα12 signaling may elucidate novel therapeutic targets in asthma. Taken together, these findings provide alternative approaches to the clinical management of airway obstruction in asthma.

Adipochemokines induced by ultraviolet irradiation contribute to impaired fat metabolism in subcutaneous fat cells.
CONCLUSIONS: These UV-induced adipochemokines may be implicated in the reduction of lipogenesis in SC fat, leading to impairment of fat homeostasis and associated comorbidities such as obesity.
