A hormone is a chemical released by one or more cells that affects cells in other parts of the organism. Only a small amount of hormone is required to alter cell metabolism. It is essentially a chemical messenger that transports a signal from one cell to another.
Scientists have completed the largest and most diverse genetic study of type 1 diabetes ever undertaken, identifying new drug targets to treat a condition that affects 1.3 million American adults.
Scientists from the RIKEN Center for Biosystems Dynamics Research (BDR) successfully created the first genetically engineered marsupial. The research and its findings published in the Current Biology journal help decipher the genetic background of special characteristics found only in marsupials.
The thyroid gland produces amino acid-based compounds known as thyroid hormones.
The urgency to remember a dangerous experience requires the brain to make a series of potentially dangerous moves: Neurons and other brain cells snap open their DNA in numerous locations--more than previously realized, according to a new study--to provide quick access to genetic instructions for the mechanisms of memory storage.
Most of us are familiar with the fact that women live longer than men. But fellas, if we told you there was one thing that could be done to increase your lifespan, would you do it?
A team of Oxford researchers successfully identified hundreds of genetic markers that are involved in two of life’s most momentous milestones.
A study has proposed a new method for developing novel drugs based on the suppression of tyrosine kinase enzymes.
In a recent study, researchers investigated how natural killer cells target breast cancer using the body's own immune system.
An inter-university research group has succeeded in constructing the gene expression network behind the vascular development process in plants. They achieved this by performing bioinformatics analysis using the 'VISUAL' tissue culture platform, which generates vascular stem cells from leaf cells.
A class of drug called monoamine oxidase inhibitors is commonly prescribed to treat depression; the medications work by boosting levels of serotonin, the brain's "happiness hormone."
A new study of more than 350,000 women found that women with diets incorporating more foods that increase inflammation in the body had a 12% increase in their risk of breast cancer compared to women who consume more anti-inflammatory diets. The new findings are being presented at NUTRITION 2021 LIVE ONLINE.
Hormonal contraceptives, e.g. the pill, the patch, and the vaginal ring, contain synthetic hormones that prevent pregnancy by either stopping ovulation, changing the cervical mucus to stop sperm from passing through the cervix and finding an egg, or changing the womb's lining to prevent a fertilized egg from being implanted in it.
A new study finds breast cancer survivors in general have higher risk of new cancer diagnosis compared to healthy individuals. The article, which appears in CANCER, states that compared to the general population in the United States, the risk of new cancer diagnoses among survivors was 20% higher for those with hormone receptor (HR) positive cancers and 44% higher for those with HR-negative cancers.
An abnormal accumulation of carbohydrates—starches and sugars—in the kernels and leaves of a mutant line of corn can be traced back to a single misregulated gene, and this finding provides insights into how the plant responds to stress.
Prolactin is a hormone that has long been thought to play an important role in breast development and growth, as well as milk production during pregnancy.
A new study offers evidence that microbes are trying to hijack the plant immune system to induce disease while also offering insights into a new mechanism.
With the help of a novel single-cell technique, researchers from the Walter and Eliza Hall Institute (WEHI) have revealed a new way to interpret the programming behind stem cells and how these cells make specific types of cells.
Scientists have found that botulinum toxin—commonly known as Botox—can expose the inner workings of the brain, in addition to smoothing out wrinkles.
As the name implies, induced pluripotent stem cells can become any type of cell in our body, and scientists have evidence that when they prompt them to become muscle progenitor cells they can help restore the sometimes debilitating muscle loss that happens with age.
Hormone drugs that reduce androgen levels may help disarm the coronavirus spike protein used to infect cells and stop the progression of severe COVID-19 disease, suggests a new preclinical study from researchers in the Abramson Cancer Center at the University of Pennsylvania and published online in Cell Press's iScience.
