Plant Meiosis
Meiosis is an essential cell-division process for ensuring genetic diversity across generations. Meiotic recombination ensures the accuracy of genetic interchange between homolous chromosomes and segregation of parental alleles. Programmed DNA double-strand breaks (DSBs), catalyzed by the evolutionarily conserved topoisomerase VIA (a subunit of the archaeal type II DNA topoisomerase)-like enzyme Spo11 and several other factors, is a distinctive feature of meiotic recombination initiation.

Mechanobiology of Metastasis
The major cause (more than 90%) of all cancer-related deaths is metastasis, thus its prediction can critically affect the survival rate. Metastases are predicted by lymph-node status, tumor size, histopathology and genetic testing. The identification of new potential prognostic factors will be an important source of risk information for the practicing oncologist, potentially leading to enhanced patient care through the proactive optimization of treatment strategies. Mechanobiology, as a branch of biomechanics and/or a branch of biology, has reached a mature stage mainly because of the significant technological and methodological advances at the cellular, subcellular, and molecular levels and the need to disclose the mechanical basis of biology. The application of mechanobiology to medicine (mechanomedicine) may help advance human health and improve diagnostics, treatment, and therapeutics of cancer.

Cadmium-Associated Molecular Signatures in Cancer Cell Models
The exposure of cancer cells to cadmium and its compounds is often associated with the development of more malignant phenotypes, thereby contributing to the acceleration of tumor progression. It is known that cadmium is a transcriptional regulator that induces molecular reprogramming, and therefore the study of differentially expressed genes has enabled the identification and classification of molecular signatures inherent in human neoplastic cells upon cadmium exposure as useful biomarkers that are potentially transferable to clinical research.

Roles of ATP-Binding-Cassette Proteins in Pluripotent Stem Cells
Pluripotent stem cells (PSCs) are highly proliferative cells that can self-renew indefinitely in vitro. Upon receiving appropriate signals, PSCs undergo differentiation and can generate every cell type in the body. These unique properties of PSCs require specific gene expression patterns that define stem cell identity and dynamic regulation of intracellular metabolism to support cell growth and cell fate transitions. PSCs are prone to DNA damage due to elevated replicative and transcriptional stress. Therefore, mechanisms to prevent deleterious mutations in PSCs that compromise stem cell function or increase the risk of tumor formation from becoming amplified and propagated to progenitor cells are essential for embryonic development and for using PSCs including induced PSCs (iPSCs) as a cell source for regenerative medicine.

Ferroptosis in Brief
Ferroptosis is a newly discovered, iron-dependent form of programmed cell death characterized by the lethal accumulation of lipid peroxides within cell membranes. This process, distinct from apoptosis or necrosis, is driven by disruptions in cellular iron homeostasis and subsequent oxidative damage. Ferroptosis plays a pivotal role in various physiological processes and diseases, including cancer, neurodegenerative disorders, and ischemic injuries. Understanding the mechanisms and regulation of ferroptosis holds promise for the development of novel therapeutic strategies, making it a burgeoning field of research in cell biology and medicine with potential applications across a wide range of health-related challenges.

Ceramide Synthase 2 in Bladder Cancer
The human CERS2 gene encodes a ceramide synthase enzyme, known as CERS2 (ceramide synthase 2). This protein is also known as LASS2 (LAG1 longevity assurance homolog 2) and TMSG1 (tumor metastasis-suppressor gene 1). Bladder cancer (BC) is a significant cause of cancer-related deaths globally, ranking as the second-most-common reason for genitourinary cancer-related mortality. The treatment of non-muscle invasive bladder cancer includes transurethral resection followed by chemotherapy to reduce recurrence chances, while muscle-invasive bladder cancers are associated with high rates of progression and metastasis and are usually treated via radical cystectomy if the tumor is organ-confined.

Mitochondrial Metabolism and Dynamics in Prostate Cancer
Prostate cancer (PCa) is the second leading cause of cancer deaths among men in Western countries. Mitochondria, the “powerhouse” of cells, undergo distinctive metabolic and structural dynamics in different types of cancer. PCa cells experience peculiar metabolic changes during their progression from normal epithelial cells to early-stage and, progressively, to late-stage cancer cells.

Molecular Mechanisms Involved in Systemic Sclerosis-Related Lung Fibrosis
Systemic sclerosis (SSc), or scleroderma, is an autoimmune connective tissue disease with one of the highest mortality rates among the rheumatic diseases. Fibrosis is recognized to be a defining feature of SSc, affecting the skin and multiple visceral organs. As a result, SSc is considered the prototypic fibrosing disease.

The Role of LncRNA in Kidney Disease
Long non-coding RNAs (lncRNAs) are a large, heterogeneous class of transcripts and key regulators of gene expression at both the transcriptional and post-transcriptional levels in different cellular contexts and biological processes. LncRNAs plays an important role in renal pathogenesis. Altered expression of lncRNAs has been increasingly closely related to the onset and development of many diseases due to their role in gene regulation processes at the transcriptional, post-transcriptional, translational, post-translational, and epigenetic levels. Therefore, increasing attention is being paid to their role as diagnostic and prognostic biomarkers and therapeutic targets in several human diseases. Regarding kidney diseases, there are numerous studies that have analyzed and demonstrated the role of lncRNAs mainly in diabetic nephropathy (DN) and acute kidney injury (AKI), and to a lesser extent in chronic kidney disease (CKD), focal segmental glomerulosclerosis (FSGs), and immunoglobulin A nephropathy (IgAN).

Mechanisms of Modulation of Mitochondrial Architecture
Mitochondrial architecture is determined by several components, which include the following: mitochondrial distribution in the cytosol, supported by interaction with the cytoskeleton; events of fission and fusion, mediated by mitochondrial dynamics proteins; mitochondrial network contact with other organelles (e.g., endoplasmic reticulum (ER), lipid droplets (LDs), lysosomes, and plasma membrane); and the lipid composition of mitochondrial membranes.
