Retrotransposon-Derived Capsid Genes PNMA1 and PNMA4 Maintain Reproductive Capacity

Mechanistic Study on How Retrotransposon-derived Capsid Genes PNMA1 and PNMA4 Maintain Reproductive Capacity — A New Research Review from Nature Aging I. Research Background and Scientific Significance Nearly half of the DNA in the human and mammalian genome is made up of retrotransposons, sequences that originally existed as “parasitic molecules” ...

A self-assembling surface layer flattens the cytokinetic furrow to aid cell division in an archaeon

1. Academic Background Since the origin of life, living organisms have needed to construct effective barriers to protect their cells from external physical and chemical damage. In the realms of bacteria and archaea, the surface layer (S-layer) is a universally present and exquisitely structured two-dimensional protein lattice that substitutes for t...

Monocytes Use Protrusive Forces to Generate Migration Paths in Viscoelastic Collagen-Based Extracellular Matrices

New Mechanism of Immune Cell Migration Revealed: How Monocytes “Pioneer Their Path” in the Tumor Microenvironment I. Academic Research Background and the Central Question Cell migration is a crucial biological process in life, encompassing embryonic development, tissue repair, immune responses, and the progression of various diseases. In the contex...

Continuous self-repair protects vimentin intermediate filaments from fragmentation

Academic Background and Research Motivation The cytoskeleton is the core structural support responsible for maintaining cell morphology and mechanical properties and is mainly composed of three major classes: actin filaments, microtubules, and intermediate filaments. Among these, intermediate filaments play an irreplaceable role in maintaining cell...

Intermediate Light Adaptation Induces Oscillatory Phototaxis Switching and Pattern Formation in Chlamydomonas

Light Adaptation Drives New Motility Patterns in Green Algae — A Review of “Intermediate light adaptation induces oscillatory phototaxis switching and pattern formation in Chlamydomonas” 1. Research Background and Scientific Questions Microswimmers at the microscopic scale, such as unicellular algae, bacteria, and sperm, are important ecological co...
