Quantitative Trait Loci (QTL)

Quantitative Trait Loci (QTL)

Quantitative Trait Loci (QTL) are specific regions of the genome that are associated with the variation of quantitative traits—traits that are influenced by multiple genes and environmental factors. Unlike simple Mendelian traits controlled by a single gene, quantitative traits such as height, yield, disease resistance, or body weight are governed by many genetic loci that each contribute small effects. QTL analysis helps researchers identify genomic regions linked to these complex traits through statistical associations between genetic markers and phenotypic variation. This approach is widely used in plant and animal breeding, evolutionary biology, and medical genetics to understand genetic architecture and improve desirable traits through marker-assisted selection and genomic selection.

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...
