DNA Double-Strand Breaks

 DNA Double-Strand Breaks

DNA Double-Strand Breaks (DSBs) are severe forms of DNA damage in which both strands of the DNA double helix are broken simultaneously, threatening genomic stability and cell survival. DSBs can arise from endogenous sources such as replication errors and reactive oxygen species, or exogenous factors like ionizing radiation and chemotherapeutic agents. Because they disrupt the continuity of both DNA strands, DSBs are highly cytotoxic and can lead to mutations, chromosomal rearrangements, or cell death if not repaired accurately. Cells rely primarily on two major repair pathways—Non-Homologous End Joining (NHEJ) and Homologous Recombination (HR)—to fix DSBs and maintain genomic integrity. Understanding DSBs is essential in fields such as genetics, cancer biology, radiation biology, and genome editing technologies like CRISPR.

Chromosomal Abnormalities

  Chromosomal Abnormalities Chromosome abnormalities refer to structural or numerical changes in chromosomes that can disrupt normal genetic function, leading to developmental disorders, congenital abnormalities, and various genetic diseases. These abnormalities may arise from errors in cell division, such as nondisjunction or chromosomal breakage, resulting in conditions like Down syndrome , Turner syndrome, Klinefelter syndrome , and various deletion or duplication syndromes. Understanding chromosome abnormalities is essential for genetic counseling, prenatal diagnosis, disease risk assessment, and research in cytogenetics and molecular genetics.

Multifactorial Genetic Conditions

Multifactorial Genetic Conditions Multifactorial genetic conditions are disorders caused by the combined effects of multiple genes and environmental factors , rather than a single gene mutation . These conditions do not follow classic Mendelian inheritance patterns and instead result from complex gene–environment interactions . Factors such as lifestyle, nutrition, infections, stress, and exposure to toxins can significantly influence disease onset and severity in genetically susceptible individuals. Common examples include diabetes, cardiovascular diseases , neural tube defects, asthma, and many neuropsychiatric disorders. Understanding multifactorial inheritance is essential for risk prediction, preventive medicine, and personalized healthcare strategies. Multifactorial inheritance, polygenic traits, gene–environment interaction, complex diseases, genetic susceptibility, environmental risk factors, non-Mendelian inheritance, disease predisposition, polygenic risk score, precision ...

Human Brain Organoids

Human Brain Organoids Model Abnormal Prenatal Neural Development Induced by Thermal Stimulation The developing human foetal brain is sensitive to thermal stimulation during pregnancy. However, the mechanisms by which heat exposure affects human foetal brain development remain unclear, largely due to the lack of appropriate research models for studying thermal stimulation. To address this, we have developed a periodic heating model based on brain organoids derived from human pluripotent stem cells. The model recapitulated neurodevelopmental disruptions under prenatal heat exposure at the early stages, providing a paradigm for studying the altered neurodevelopment under environmental stimulation. Our study found that periodic heat exposure led to decreased size and impaired neural tube development in the brain organoids. Bulk RNA-seq analysis revealed that the abnormal WNT signalling pathway and the reduction of G2/M progenitor cells might be involved in heat stimulation. Further investi...
