Article Synopsis
  • - Chemical leukoderma is a skin condition caused by chemical exposure, leading to loss of skin pigment due to the death of melanocytes, the cells responsible for pigmentation.
  • - This condition is particularly concerning in developing countries like India, with links identified between household chemicals derived from phenols and catechol and its onset.
  • - Its development is influenced by a combination of genetic predisposition and environmental factors, with recent studies highlighting the significant role of chemical exposure in its initiation and progression.

Article Synopsis
  • The Halari donkey breed, an indigenous Indian species, is facing a rapid decline in population.
  • Their milk is similar to human milk, offering benefits like probiotic diversity and lower allergenic properties, particularly useful for infants allergic to cow or buffalo milk.
  • This study successfully isolated DNA from the milk somatic cells of Halari donkeys and confirmed the presence of the k-casein gene, demonstrating the potential for non-invasive DNA extraction in further molecular research.

Article Synopsis
  • The study focused on identifying genetic variations (SNPs) in the gene of Indian horse and donkey breeds, highlighting their influence on equine racing, riding, and gaitedness.
  • Researchers sequenced samples from 72 Indian horses and 33 donkeys, discovering a significant non-synonymous mutation in both species at nucleotide 878, affecting how proteins are coded.
  • The findings revealed that donkey breeds exhibited higher genetic diversity compared to horses, with the identified mutations potentially impacting gaitedness in horses, particularly those bred for harness racing.

Sensing surface topography, an upsurge of signaling biomolecules, and upholding cellular homeostasis are the rate-limiting spatio-temporal events in microbial attachment and biofilm formation. Initially, a set of highly specialized proteins, . conditioning protein, directs the irreversible attachment of the microbes.

Article Synopsis
  • India has diverse horse and pony breeds, and this study focuses on analyzing the Myostatin (MSTN) gene for performance in eight different Indian horse breeds.
  • Researchers amplified and sequenced part of the MSTN gene, discovering single nucleotide polymorphisms (SNPs) indicating genetic variations among the breeds.
  • This study is the first to document MSTN gene variations in Indian horses, offering insights into predicting their athletic performance and understanding their genetic relationships across geographical regions.*

Long-term exposure to organic solvents is known to affect human health posing serious occupational hazards. Organic solvents are genotoxic, and they can cause genetic changes in the exposed employees' somatic or germ cells. Chemicals such as benzene, toluene, and gasoline induce an excessive amount of genotoxicity results either in genetic polymorphism or culminates in deleterious mutations when concentration crosses the threshold limits.

Introduction: The mutational changes in Polycystin-1(PC-1) encoded by PKD1 gene is the main cause of Autosomal Dominant Polycystic kidney disease (ADPKD). The pathological changes in renal epithelial cells and multiple cyst formation occur due to activation of cascade of signalling pathways and membrane renal transporters (RTs). Our study have focused on the identification, of different RTs, their interactions with Polycystin-1 and other selected target proteins to find out their role in pathogenesis.

Cytochrome P450 (CYP) 1A1 and CYP1B1 are important phase I xenobiotic metabolizing enzymes involved in the metabolism of numbers of toxins, endogenous hormones, and pharmaceutical drugs. Polymorphisms in these phase I genes can alter enzyme activity and are known to be associated with cancer susceptibility related to environmental toxins and hormone exposure. Their genotypes may also display ethnicity-dependent population frequencies.

Aim: It is well known that polycyclic aromatic hydrocarbons (PAHs) such as benzo (a) pyrene have carcinogenic properties and may cause many types of cancers in human populations. Genetic susceptibility might be due to variation in genes encoding for carcinogen metabolizing enzymes, such as cytochrome P-450 (CYP450). Our study aimed to investigate the effect of genetic polymorphisms of CYP1A1 (m1 and m2) on genetic damage in 115 coal-tar workers exposed to PAHs in their work place.

The aim of the study was to assess the expression of transcriptional factor genes and embryonic stem cell-like characters in the placental membrane of buffalo (Bubalus bubalis). Along with the placenta, amniotic fluid, maternal peripheral blood, and umbilical cord blood samples were taken for the future study. The isolation and culture of cells from the placental membrane was followed by the determination of RT-PCR-based markers (Oct-4, Nanog, Sox-2, alkaline phosphatase, stem cell factor, and Nestin) of these cells.

Heterogeneous amniotic fluid contains various cell types. The aim of this study was to characterize and differentiate some of the key stemness attributes of the amniotic fluid-derived cells in buffalo (Bubalus bubalis). The amniotic fluid (AF) cells were cultured without feeder cells, in DMEM containing 15% FBS, 1% non-essential amino acids, 1% penicillin/streptomycin/ampicillin, 1% vitamin solution, and 1% l-glutamine in 5% CO(2) in humidified air at 38.

Chromosomal aberrations (CAs) in peripheral blood lymphocytes and micronuclei (MN) in exfoliated buccal cells have been used for decades as cytogenetic biomarkers to investigate genotoxicity among occupationally or environmentally exposed population. In our study, we investigated the association of increased cytogenetic damage with genetic polymorphism in glutathione-S transferase genotypes among occupationally exposed 115 coaltar workers and 105 unexposed controls. We found higher mean value of chromosome aberrations (chromatid type-2.

DNA damage was evaluated by alkaline comet assay in peripheral blood lymphocytes of 115 coal-tar workers occupationally exposed to polycyclic aromatic hydrocarbons (PAHs) and 105 control subjects. The effect of polymorphisms of glutathione S-transferase (GST) genotypes on the DNA damage was assessed. The mean tail moment (TM) value in the coal-tar workers was significantly higher as compared to the control subjects (12.

In the present study, we have investigated the influence of polymorphism of GSTM1 and GSTT1 genes and confounding factors such as age, sex, exposure duration and consumption habits on cytogenetic biomarkers. Frequency of sister chromatid exchanges (SCEs), high frequency cell (HFC) and cytokinesis blocked micronuclei (CBMN) were evaluated in peripheral blood lymphocytes of 115 occupationally exposed road construction workers and 105 unexposed individuals. The distribution of null and positive genotypes of glutathione-S transferase gene was evaluated by multiplex PCR among control and exposed subjects.
