Forensic genetic detectives of Hyderabad crack Tamil Nadu monitor lizard case


The CCMB researchers said that forensic genetic evidence is a powerful tool to secure convictions in wildlife crimes.

The forensic genetic detectives of Hyderabad have uncovered a wildlife crime involving the mystery of occult and how the gullible can be taken for a ride by poachers. The DNA investigators in Hyderabad received small pieces of plant material for analysis. It turned out that the plant materials were, in reality, the gonads of male Bengal monitor lizard, which was killed by the poachers in Tamil Nadu.

Published as a case study in Springer Nature (September, 2024), the group of researchers from Hyderabad-based Centre for Cellular and Molecular Biology (CCMB), through their DNA analysis, helped investigators from Tamil Nadu to unravel the mystery and prosecute the poachers.

The poachers harvested the forked penises of monitor lizards and fraudulently sold them to individuals as the roots of a very rare plant Martynia annua, which are used in occult practices by believers. The poachers modified the penises of monitor lizards to resemble the plant roots, (which look like folded hands), and made it even more complex for investigators to make an accurate identification.

The CCMB researchers said that forensic genetic evidence is a powerful tool to secure convictions in wildlife crimes. “The bifurcated hemipenes (gonads) of any of the four species of Monitor lizards found in India are illegally traded under the name ‘Hatha Jodi’ (a plant root from Martynia annua). A rare plant root is misrepresented as a powerful charm capable of bringing property and good fortune to its possessor. As a result, there is a suspected large-scale poaching of monitors in India to fuel the trade of ‘Hatha Jodi’,” the CCMB researchers in the paper said.

Monitor lizards are copiously poached for their meat, which is considered a delicacy and assumed to have medicinal properties. Studies have documented that the products prepared from the monitor lizards are used to treat various diseases, i.e., asthma, haemorrhoids, rheumatism, and arthritis. The genital organs from Monitor lizards are traded in the name of ‘Hatha Jodi’, the root of the Tiger’s Claw plant and used for human welfare, the researchers said.

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 ...

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. Chromosome abnormalities, chromosomal disorders, chromosomal mutations, aneuploidy, structural chromosome abnormalities, nondisjunction, deletion syndrome, duplication syndrome , translocation, inversion, cytogenetics, karyotyping, prenatal diagnosis , genetic testing, genomic instability, Down syndrome, Turner syndrome, Klinefelter syn...

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...
