FEBS Open Bio, EarlyView.Representation of the suggested mode of action of lactoferrin (Lf) in nonsmall cell lung cancer (NSCLC) A549 cells. Lf induces activation of caspase‐3 by activating p53 and AChE leading to decreased ACh concentrations. In turn, ACh signaling leads to activation of VEGF and AKT and blocking of caspase‐3.

Regulation of Muscle Microcirculation in Health and Diabetes [PDF]
Diabetes & Metabolism Journal, 2012 Insulin increases microvascular perfusion and substrate exchange surface area in muscle, which is pivotal for hormone action and substrate exchange, by activating insulin signaling cascade in the endothelial cells to produce nitric oxide.

Insulin Receptor Substrate-4 Is Expressed in Muscle Tissue without Acting as a Substrate for the Insulin Receptor [PDF]
Endocrinology, 2003 Insulin receptor substrate (IRS) proteins represent key elements of the insulin-signaling cascade. IRS-4 is the most recently characterized member of the IRS family with an undefined in vivo function. In contrast to IRS-1 and IRS-2, IRS-4 exhibits a limited tissue expression, and IRS-4 protein has not been detected in any mouse or primary human tissue ...

Molecular determinants of signal transduction in tropomyosin receptor kinases
FEBS Open Bio, EarlyView.Tropomyosin receptor kinases control critical neuronal functions, but how do the same receptors produce diverse cellular responses? This review explores the structural mechanisms behind Trk signaling diversity, focusing on allosteric modulation and ligand bias.

Insulin signaling is acutely required for long-term memory in Drosophila
Frontiers in Neural Circuits, 2015 Memory formation has been shown recently to be dependent on energy status in Drosophila. A well-established energy sensor is the insulin signaling (InS) pathway.

Vitamin A Transport Mechanism of the Multitransmembrane Cell-Surface Receptor STRA6. [PDF]
, 2015 Vitamin A has biological functions as diverse as sensing light for vision, regulating stem cell differentiation, maintaining epithelial integrity, promoting immune competency, regulating learning and memory, and acting as a key developmental morphogen ...

FEBS Open Bio, EarlyView.Induction of diabetes in three different mouse strains uniformly resulted in an increase in TNAP activity and a reduction in pyrophosphate (PPi) in the circulation. Inhibition of TNAP restored plasma PPi. Diabetes‐induced calcification in the media layer of the aorta was detected only in the Abcc6−/− strain, which is predisposed to ectopic ...

FEBS Open Bio, EarlyView.Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...
