The retinoblastoma protein (Rb), a key regulator of cell cycle progression, can bind the transcription factor E2F converting it from a positive transcriptional factor capable of driving cells into S ...

Although a biphasic dependence of cell migration speed on cell-substratum adhesiveness has been predicted theoretically, experimental data directly demonstrating a relationship between these two ...

Muscle-on-chip systems are three-dimensional human muscle cell bundles cultured on collagen scaffolds. A Stanford University research team sent some of these systems to the International Space Station ...

The film explores the muscular system of the human body, detailing the roles and functions of the three types of muscles: skeletal, smooth, and cardiac. Skeletal muscles, which are voluntary and work ...

Metoclopramide (N-(diethylaminoethyl)-2-methoxy-4-amino-5-chlorobenzamide) has been investigated with human gastrointestinal smooth-muscle preparations in vitro. Small-intestinal and colonic circular ...

Repeated exercise, or wasting, can change the way key genes work.

How muscle changes with ageing, and tries to fight its effects, is now better understood at the cellular and molecular level with the first comprehensive atlas of ageing muscles in humans. Researchers ...

A new study by researchers at Yale and Johns Hopkins University has discovered how asthmatic bronchial spasms — muscle contractions in the airway that cause difficulty breathing in asthma patients— ...
