Stem cells of an embryo are pluripotent – they can grow into almost any cell type in the body. Induced pluripotent stem cells (iPSC) are artificially reprogrammed body cells that can be made to function like embryonic stem cells, offering therapeutic advantages. However, understanding the genetic machinations of pluripotent stem cells is vital to successfully culture iPSC and is an active research area. In an exciting breakthrough, scientists have identified the group of genes responsible for maintaining distinct states of human pluripotency.
A team of researchers from the National Institute of Immunology, New Delhi, Indian Institute of Technology Delhi, New Delhi, All India Institute of Medical Sciences, New Delhi, and Agency for Science, Technology and Research (A*STAR), Singapore, has revealed how crosstalk between two molecular pathways in the cells of the gut mediates the aberrant inflammation in Inflammatory Bowel Disease.
In a new study, researchers from the Indian Institute of Technology (IIT) Gandhinagar and the Indian Institute of Science (IISc), Bengaluru, have demonstrated the functioning of a motor protein responsible for recycling material inside a cell. These findings are crucial since faulty recycling in cells is responsible for many disorders including Alzheimer’s disease, Huntington’s disease, and Cancer.
Emerging dominant strains of the coronavirus are a cause of concern as they impact the course of the pandemic, prompting scientists to track the mutation patterns of the virus closely. In this collaborative study, an analysis of the SARS-CoV-2 global genomic database revealed the trends of point-mutations occurring in the virus.
The tuberculosis bacteria is notorious for its ability to stay dormant for years within the human body, evading the immune system and always one step away from causing aggressive infection. Now, a study from researchers at Translational Health Science and Technology Institute (THSTI), Faridabad, and Institute of Microbial Technology (IMTech), Chandigarh, has investigated a novel molecular pathway that helps the bacteria avoid the notice of the immune system.
The bacterial world contains a treasure trove of potent compounds with biological activities that can be harnessed for human benefit. Researchers from CSIR-National Chemical Laboratory, Pune and the Jawaharlal Nehru Tropical Botanic Garden and Research Institute, Thiruvananthapuram, have recently found that Urdamycin, a compound produced by Streptomyces bacteria, has the ability to induce cell death in cancer cells.
One of the main challenges in cancer chemotherapy is how to selectively kill tumour cells while leaving healthy cells alive. Researchers at the Indian Institute of Science Education and Research (IISER) Pune have come up with a novel approach where they use an artificially constructed ion channel and certain biochemical peculiarities of cancer cells to induce cell death in a highly targeted manner.
