Olfactomedin-like 3 promotes PDGF-dependent pericyte proliferation and migration during embryonic blood vessel formation.

Pericytes promote vessel stability and their dysfunction causes pathologies due to blood vessel leakage. Previously, we reported that Olfactomedin-like 3 (Olfml3) is a matricellular protein with proangiogenic properties. Here, we explored the role of Olfml3 in a knockout mouse model engineered to suppress this protein.

Inhibition of host NOX1 blocks tumor growth and enhances checkpoint inhibitor-based immunotherapy.

NADPH oxidases catalyze the production of reactive oxygen species and are involved in physio/pathological processes. NOX1 is highly expressed in colon cancer and promotes tumor growth. To investigate the efficacy of NOX1 inhibition as an anticancer strategy, tumors were grown in immunocompetent, immunodeficient, or NOX1-deficient mice and treated with the novel NOX1-selective inhibitor GKT771.

Junctional adhesion molecule C (JAM-C) dimerization aids cancer cell migration and metastasis.

Most cancer deaths result from metastasis, which is the dissemination of cells from a primary tumor to distant organs. Metastasis involves changes to molecules that are essential for tumor cell adhesion to the extracellular matrix and to endothelial cells. Junctional Adhesion Molecule C (JAM-C) localizes at intercellular junctions as homodimers or more affine heterodimers with JAM-B.

Inhibitory role of oxytocin on TNFα expression assessed in vitro and in vivo.

Aim: Oxytocin administration to diet-induced obese (DIO) rodents, monkeys and humans decreases body weight and fat mass with concomitant improvements in glucose metabolism. Moreover, several studies show an immunomodulatory role of oxytocin in a number of settings (such as atherosclerosis, injury, sepsis). This study aims to shed some light on the effects of oxytocin on macrophage polarization and cytokine production, as well as its possible impact on these parameters in adipose tissue in DIO mice with impaired glucose metabolism.
