ABSTRACT Meiosis is a hallmark of sexual reproduction because it represents the transition from one life cycle to next and, in animals, meiosis produces gametes. Why evolved has been debated and most studies have focused on recombination parental alleles as main function meiosis. However, 40 years ago, Robin Holliday proposed that an essential oppose consequence successive mitoses cause cellular aging. Cellular aging results accumulated defective organelles proteins modifications chromatin form DNA methylation histone referred collectively epigenetic marks. Here, recent findings supporting hypothesis opposes are reviewed placed context diversity cycles eukaryotes, including yeast, flowering plants bryophyte Marchantia.

Non-communicable diseases (NCDs) pose a global health challenge, leading to substantial morbidity, mortality, and economic strain. Our review underscores the escalating incidence of NCDs worldwide highlights potential regenerative agriculture (RA) products in mitigating these diseases. We also explore efficacy dietary interventions NCD management prevention, emphasizing superiority plant-based diets over those high processed foods red meat. Examining role gut microbiome various diseases, including liver disorders, allergies, metabolic syndrome, inflammatory bowel disease, colon cancer, we find compelling evidence implicating its influence on disease development. Notably, modifications can positively affect microbiome, fostering symbiotic relationship with host making this critical strategy prevention treatment.

The nearly unlimited number of “glycoforms” that may exist nature difficult study due glycosylation modifications being associated with non‐genome coded posttranscription post‐translation processes. Specific products generated by dependent on concentration sub‐cellular locations glycan synthesis processing enzymes. An indirect “high‐throughput” approach is characterize enzymes (hydrolases transferases) single cell sequencing all types tissue diseases.

The holobiont concept (i.e., multiple living beings in close symbiosis with one another and functioning as a unit) is revolutionizing our understanding of biology, especially marine systems. earliest was likely syntrophic partnership at least two prokaryotic members. Since then, has enabled organisms to conquer all ocean habitats through the formation holobionts wide spectrum complexities.

The rapid development of research on archaea by biochemists in the 1980s led to a completely unexpected discovery. Alongside characteristics unique them, such as structure their lipids, exhibited numerous traits that brought them closer eukaryotes. In 1990s, Karl Stetter redesigned Carl Woese's universal tree life, highlighting lines leading organisms whose optimal growth temperatures exceed 80 degree Celsius. Starting 2000s, genome sequencing across three domains life enabled construction phylogenetic trees based universally conserved proteins. context 2D hypothesis, eukaryotic proteins distribution is limited certain groups are called ESPs (eukaryotic signature proteins) because they suggest an evolutionary proximity between these and hypothesis Asgard our ancestors has gained popularity it motivated teams search within for evidence could support this hypothesis.

Glycolysis, present in most organisms, is evolutionarily one of the oldest metabolic pathways. It has great relevance at a physiological level because it responsible for generating ATP cell through conversion glucose into pyruvate and reducing nicotinamide adenine dinucleotide (NADH) (that may be fed electron chain mitochondria to produce additional by oxidative phosphorylation), as well producing intermediates that can serve substrates other processes. Glycolysis takes place 10 consecutive chemical reactions, each which catalysed specific enzyme. Although energy transduction metabolism main function this pathway, involvement virulence, growth, pathogen–host interactions, immunomodulation adaptation environmental conditions are functions attributed pathway. In humans, where glycolysis occurs mainly cytosol, mislocalization some glycolytic enzymes various subcellular locations, alterations their expression regulation, been associated with development progression diseases. review, we describe role pathogenesis diseases clinical interest. addition, potential these targets drug use diagnostic prognostic markers pathologies also discussed.
