Microtubule Dynamics in Toxoplasma gondii
The success of the intracellular parasite Toxoplasma gondii in invading host cells relies on the apical complex, a specialized microtubule cytoskeleton structure associated with secretory organelles. The T. gondii genome encodes three isoforms of both α- and β-tubulin, which undergo specific post-translational modifications (PTMs), altering the biochemical and biophysical proprieties of microtubules and modulating their interaction with associated proteins. Tubulin PTMs represent a powerful and evolutionarily conserved mechanism for generating tubulin diversity, forming a biochemical ‘tubulin code’ interpretable by microtubule-interacting factors.

Autophagy in Metabolic Regulation of Cancer Stem Cells
The presence of a specific population of cells within the tumor mass, commonly known as cancer stem cells (CSCs), is thought to initiate tumor formation, maintenance, resistance, and recurrence. Understanding the molecular mechanisms involved in CSC proliferation, self-renewal, and dormancy may provide important clues for developing effective therapeutic strategies. Autophagy, a catabolic process, has long been recognized to regulate various physiological and pathological processes. In addition to regulating cancer cells, studies have identified a critical role for autophagy in regulating CSC functions. Autophagy is activated under various adverse conditions and promotes cellular maintenance, survival, and even cell death.

Staphylococcus aureus-Derived Extracellular Vesicles and Atopic Dermatitis Pathophysiology
Atopic dermatitis (AD) is a chronic and relapsing inflammatory cutaneous disease. The role of host defense and microbial virulence factors in Staphylococcus aureus skin colonization, infection, and inflammation perpetuation in AD remains an area of current research focus. Extracellular vesicles (EV) mediate cell-to-cell communication by transporting and delivering bioactive molecules, such as nucleic acids, proteins, and enzymes, to recipient cells. Staphylococcus aureus spontaneously secretes extracellular vesicles (SA-derived EVs), which spread throughout the skin layers. Research has shown that SA-derived EVs from AD patients can trigger cytokine secretion in keratinocytes, shape the recruitment of neutrophils and monocytes, and induce inflammatory AD-type lesions in mouse models, in addition to their role as exogenous worsening factors for the disease.

New Insights into the Anti-Aging Properties of Mushrooms
Aging is a complex biological process that is influenced by both intrinsic and extrinsic factors. Recently, it has been discovered that reactive oxygen species can accelerate the aging process, leading to an increased incidence of age-related diseases that are characteristic of aging.

Bioactive Peptides Derived from Hen Egg Proteins
Hen eggs, characterized by high protein and digestibility, are an excellent source of food-derived bioactive peptides. Some peptides comprising fewer than six amino acids may resist gastrointestinal digestion and remain intact as they cross the intestinal epithelium.

Yeast-Based Screening of Anti-Viral Molecules
Viruses are microscopic, subcellular biological entities that mainly consist of proteins and nucleic acid [ssDNA or dsDNA or (+) ssRNA or (−) ssRNA or both DNA and RNA (for example, Leukovirus)]. Yeast emerged as a model of choice for in vivo assays. Several features that compel the use of a yeast-based platform for screening purposes are briefly highlighted here.

Isoprene-Derived Signaling Molecules in Plant System
Isoprene, a lipophilic and unstable compound with the chemical formula C5H8, is transported to plant chloroplasts via the 2-C-methyl-d-erythritol 4-phosphate (MEP) pathway, which relies on photosynthesis. Although only about 20% of terrestrial plants can synthesize isoprene, those that emit it are more adaptable to oxidative and thermal stresses. Plants use volatile organic compounds (VOCs) to communicate with other living things. Isoprene, monoterpenes and sesquiterpenes make up the largest class of volatile organic compounds (VOCs) emitted by plants terpenes. In plant–plant interactions, mono- and sesquiterpenes are well-known communication molecules. On the other hand, isoprene, the smallest and most often released terpene, is instead given a role in fighting abiotic stressors.

-Omics Approaches in Studies of Polystyrene MNP Toxicity
The investigation of the toxicity mechanism of micro- and nanoplastics (MNPs) is a topic of major concern for the scientific community. The use of transcriptomics, proteomics, and metabolomics has suggested that the main pathways affected by polystyrene (PS) MNPs are related to energy metabolism, oxidative stress, immune response, and the nervous system, both in fishes and aquatic invertebrates.

Temperatures and Light Effect on Dormancy
Dormancy is defined as the sum of processes that create a situation wherein embryonic tissues are unable to grow, even under environmental conditions that generally favor growth and development. The effects of temperature to break dormancy, from work done on peach, can be summarized as follows: Effective temperatures are between −2 °C and 13 °C, and the most effective being 4–8 °C with reduced efficiency at higher and lower temperatures. Moderate temperatures between 13 °C and 16 °C that will not break dormancy alone, when occurring in a daily cycle after previous chilling, enhance the effect of chilling. On the other hand, temperatures higher than 18 °C in a daily cycle will nullify former chilling. This negative effect of high temperatures increases the longer the duration and the higher the temperature. However, when cycles are longer than a day, the chilling effect is final and cannot be nullified by high temperatures. Apart from the effects of temperature on dormancy, light effects on dormancy in peach trials had also been detected Clearly, the dormant vegetative buds perceive light signals and react to light during dormancy and bud breaks. On the other hand, flower buds in peach were found to be non-responsive to light. Dormancy in vegetative buds is induced by short days. During endodormancy, the limitation of light and even total darkness enhance bud breaks in spring, compared to buds receiving natural light. But darkness in spring will prevent vegetative bud break even following sufficient chilling during winter.  So, there is an analogy between chilling and darkness.

RBPs Associated with Cardiomyopathies
Cardiomyopathies are structural and functional abnormalities of the myocardium and represent a heterogenous group of cardiac disorders, including dilated cardiomyopathy (DCM), hypertrophic cardiomyopathy (HCM), restrictive cardiomyopathy (RCM), and arrhythmogenic cardiomyopathy (ACM). RNA-binding proteins (RBPs) are major regulators of gene expression at the post-transcriptional level and contribute to generating protein abundance and diversity within a cell.
