MAL2 and rab17 selectively redistribute invadopodia proteins to laterally-induced protrusions in hepatocellular carcinoma cells.
Mol Biol Cell

Department of Biology, The Catholic University of America, Washington, DC, 20064.
MAL2 (myelin and lymphocyte protein 2) and rab17 have been identified as hepatocellular carcinoma tumor suppressors. However, little is known how their functions in hepatic polarized protein sorting/trafficking translates into how they function in the epithelial to mesenchymal transition and/or the mesenchymal to epithelial transition in metastases. To investigate this, we expressed MAL2 and rab17 alone or together in hepatoma-derived Clone 9 cells (that lack endogenous MAL2 and rab17).

Importance: Surgeon stress can influence technical and nontechnical skills, but the consequences for patient outcomes remain unknown.
Objective: To investigate whether surgeon physiological stress, as assessed by sympathovagal balance, is associated with postoperative complications.
Design, Setting, And Participants: This multicenter prospective cohort study included 14 surgical departments involving 7 specialties within 4 university hospitals in Lyon, France.
Observing Changes in Motoneuron Characteristics Following Distorted Sensorimotor Input via Blood Flow Restriction.
J Appl Physiol (1985)
January 2025
Department of Electrical Engineering and Automation, Aalto University, Espoo, Finland.
Disruption of the blood supply to a limb in conjunction with active movement boosts muscle growth, aids in rehabilitation, and allows controlled exploration of the sensorimotor system. Yet, the underlying neuromechanical changes have not been observed in great detail. This study aims to report the acute neuromuscular effects of temporary blood flow restriction (BFR) through behavioral changes at the level of motor units (MUs) using high-density surface electromyography on the abductor digiti minimi muscle during 20 trapezoidal and sinusoidal isometric force tracking tasks (5 pre-BFR, 5 during BFR, and 10 post-BFR).

Tenomodulin (TNMD) is related to chondromodulin-1, a cartilage-derived growth regulator. It is specifically expressed in hypovascular connective tissues, including tendons and ligaments. Vascular endothelial growth factor A (VEGF-A) and calcitonin gene-related peptide (CGRP) correlate with angiogenesis and neurogenesis, respectively, during development.

Metanephrines (metanephrine [MN] and normetanephrine [NMN]) are O-methylated metabolites derived from the catecholamines, epinephrine, and norepinephrine, respectively. High concentrations of metanephrines have been observed in individuals with pheochromocytoma, a neuroendocrine tumor. Measurement of metanephrines in urine is used to screen for the tumor.
