Study reveals key aspect of mechanism of gene expression regulation
Updated : 3 years, 1 month ago IST
Despite the fact that they both develop in the same person and share the same genes, skin cells and brain cells are clearly distinct. They differ because each cell type expresses a different set of genes than the others. Cellular mechanisms that tightly regulate gene expression make this pos

Researchers using cancer cells as logic gates to determine what makes them
Updated : 3 years, 1 month ago IST
Cancer cells migrate through the body for multiple reasons; some are simply following the flow of a fluid, while others are actively following specific chemical trails. So how do you determine which cells are moving and why? Purdue University researchers have reverse-engineered a cellular si

Researchers suggest effects of resistance training in older adults
Updated : 2 years, 4 months ago IST
A protein response that takes place at the cellular level as a result of ageing includes a balance between oxidants and antioxidants, low-grade inflammation, and is the cause of many medical conditions.

Study finds how specific nutrients affect neuronal development
Updated : 3 years, 1 month ago IST
It appears that nutrition affects an organism's physiological status at every stage of life. Although it is well recognised that neuronal development, particularly the growth of dendrites and axons, is metabolically demanding, little is known about the effects of different foods on neuronal

Enzyme 'atlas' helps researchers decipher cellular pathways
Updated : 3 years, 2 months ago IST
A new atlas maps more than 300 protein kinases found in human cells and identifies which types of protein substrates they target. The atlas could help scientists understand what happens when cells become cancerous or are treated with specific drugs.

Study finds new cellular component important for sense of smell
Updated : 3 years, 2 months ago IST
In the neurons that our noses utilise to detect smell, scientists at Umea University in Sweden have found a previously unidentified cellular component called an organelle. The discovery may spur more studies into the COVID-19 symptom of poor smell perception.

Researchers discover new cellular component with importance for sense of s
Updated : 3 years, 2 months ago IST
Researchers at Umea University in Sweden have discovered a previously unknown cellular component, an organelle, inside neurons that we use to perceive smell. The discovery could lead to more research into impaired sense of smell, which is a common symptom of COVID-19.

Self-assembling proteins can store cellular 'memories': Study
Updated : 3 years, 2 months ago IST
As cells perform their everyday functions, they turn on a variety of genes and cellular pathways. MIT engineers have now coaxed cells to inscribe the history of these events in a long protein chain that can be imaged using a light microscope.

Study reveals cells have 'memories' stored in protein chains
Updated : 3 years, 2 months ago IST
According to a study published in the journal 'Nature Biotechnology', cells generate chains of proteins to record certain 'cellular memories'.

Cellular messengers improve cancer therapy: Research
Updated : 3 years, 2 months ago IST
Nano-sized membrane bubbles known as extracellular vesicles activate the immune system in mice and seem to render their tumours sensitive to a type of immunotherapy drug called a checkpoint inhibitor. This is according to a new study published in Cancer Immunology Research by researchers at
