The Concept of Mechanism in Biology [PDF]
Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences, 2012 The concept of mechanism in biology has three distinct meanings. It may refer to a philosophical thesis about the nature of life and biology (‘mechanicism’), to the internal workings of a machine-like structure (‘machine mechanism’), or to the causal ...

RNA Interference: Biology, Mechanism, and Applications [PDF]
Microbiology and Molecular Biology Reviews, 2003 SUMMARY Double-stranded RNA-mediated interference (RNAi) is a simple and rapid method of silencing gene expression in a range of organisms. The silencing of a gene is a consequence of degradation of RNA into short RNAs that activate ribonucleases to target homologous mRNA.

Magnetic field effects in biology from the perspective of the radical pair mechanism [PDF]
Journal of the Royal Society Interface, 2022 Hundreds of studies have found that weak magnetic fields can significantly influence various biological systems. However, the underlying mechanisms behind these phenomena remain elusive.

Ferroptosis interaction with inflammatory microenvironments: Mechanism, biology, and treatment.
Biomedicine & pharmacotherapy = Biomedecine & pharmacotherapie, 2022 Ferroptosis is a newly discovered form of regulated cell death. Ferroptosis is an iron-dependent lipid peroxidation reaction of cell membrane lipids, and it is closely related to the occurrence and development of many inflammatory diseases, such as ...

Identification of quiescent FOXC2+ spermatogonial stem cells in adult mammals
eLife, 2023 In adult mammals, spermatogenesis embodies the complex developmental process from spermatogonial stem cells (SSCs) to spermatozoa. At the top of this developmental hierarchy lie a series of SSC subpopulations.

SPF45/RBM17-dependent, but not U2AF-dependent, splicing in a distinct subset of human short introns
Nature Communications, 2021 The length distribution of human pre-mRNA introns is very extensive. The authors demonstrate that splicing in a subset of short introns is dependent on SPF45 (RBM17), which replaces authentic U2AF-heterodimer on the truncated poly-pyrimidine tracts and ...

Mechanics rules cell biology [PDF]
BMC Sports Science, Medicine and Rehabilitation, 2010 Cells in the musculoskeletal system are subjected to various mechanical forces in vivo. Years of research have shown that these mechanical forces, including tension and compression, greatly influence various cellular functions such as gene expression, cell proliferation and differentiation, and secretion of matrix proteins.

Europhysics News, 2020 Mechanics plays a key role in life, from simple tasks like providing protective shielding to highly complex ones such as cell division. To understand mechanical properties on the organism level, we need to zoom in to its constituent cells, then zoom back out to see how they collectively build tissues.
