Signal transduction pathways involved in the mitogenic activity of pleiotrophin. Implication of mitogen-activated protein kinase and phosphoinositide 3-kinase pathways.

The Journal of biological chemistry, 1997
Pleiotrophin (PTN) is a developmentally regulated protein which exhibits neurite-outgrowth, mitogenic, and angiogenic properties. It has also been shown to be involved in tumor growth and metastasis. Here we used primary BEL (bovine epithelial lens) cells to investigate the signal transduction pathways involved in the mitogenic activity of recombinant ...

Pasta, a Versatile Transcriptomic Clock, Maps the Chemical and Genetic Determinants of Aging and Rejuvenation

Advanced Science, EarlyView.
Pasta is a transcriptomic aging clock built on an age‐shift learning framework and trained on 17 000 samples across 21 datasets. It accurately predicts relative biological age across tissues, platforms, and species, captures stemness‐to‐senescence transitions, and identifies age‐modulatory perturbations.

TNF receptor–related factor 3 inactivation promotes the development of intrahepatic cholangiocarcinoma through NF‐κB‐inducing kinase–mediated hepatocyte transdifferentiation

Hepatology, EarlyView., 2022
Abstract Background and Aims Intrahepatic cholangiocarcinoma (ICC) is a deadly but poorly understood disease, and its treatment options are very limited. The aim of this study was to identify the molecular drivers of ICC and search for therapeutic targets.

Hypothalamic Control of Liver Health and Disease: From Circuits to Pathophysiology and Therapies

Advanced Science, EarlyView.
This review delineates the hypothalamic circuits that control liver homeostasis via autonomic and neuroendocrine pathways. Dysregulation of this hypothalamus–liver axis drives disease progression across a spectrum including steatotic liver disease, liver inflammation and injury, fibrosis, cirrhosis, and hepatocellular carcinoma.

Myeloid p38 activation maintains macrophage–liver crosstalk and BAT thermogenesis through IL‐12–FGF21 axis

Hepatology, EarlyView., 2022
Physiological activation of myeloid p38 controls macrophage IL‐12 production and crosstalk to the liver by modulating hepatic FGF21, and subsequently, brown adipose tissue thermogenesis during obesity Abstract Obesity features excessive fat accumulation in several body tissues and induces a state of chronic low‐grade inflammation that contributes to ...

Dimeric dipeptide mimetic the 1st loop of nerve growth factor of GK-6, which activates PI3K/AKT and MEK/MAPK/ERK, causes a neuronal type differentiation of PC12 cells

Фармакокинетика и Фармакодинамика, 2017
Dimeric dipeptide mimetic 1st loop of NGF GK-6 (10-6M) activating as phosphatidylinozitol 3-kinase/Akt and mitogen-activated protein kinase MEK/MAPK/ERK) signaling cascades causes PC12 cell differentiation into neuron-like cells. At the same time dimeric

Isobavachromene ameliorates insulin resistance via inactivating the MAPK/NF-κB signaling pathway

Food Science and Human Wellness
Inflammation caused by obesity, particularly in adipose tissue and the liver, can lead to insulin resistance (IR) and trigger type 2 diabetes mellitus (T2DM). It is crucial to identify therapeutic agents that alleviate IR by reducing inflammation.

A Novel Pak1 Activator Ameliorates ER Stress for HFpEF Therapy

Advanced Science, EarlyView.
Chronic metabolic stress is a major contributor to HFpEF progression. Under prolonged metabolic stress, Pak1 activity becomes impaired, contributing to disrupted ER proteostasis, cardiomyocyte apoptosis, fibrosis, and diastolic dysfunction. Mechanistically, Pak1 overexpression activates the ERK1/2–MNK1–eIF4E signaling axis, promotes translational ...
