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.
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.
Consumption of a diet with high fat levels increases the risk of fatty liver, obesity, cardiovascular diseases, and type 2 diabetes.
Hormones produced by the thyroid gland are essential regulators of organ function. The absence of these hormones either through thyroid dysfunction due to, for example, irradiation, thyroid cancer or autoimmune disease or thyroidectomy leads to symptoms like fatigue, feeling cold, constipation, and weight gain.
The vegan diet is on-trend. How this type of diet affects health is the subject of scientific studies. In a new study from the German Federal Institute for Risk Assessment (BfR), the bone health of 36 vegans, as well as 36 people following a mixed-food diet, was determined with an ultrasound measurement of the heel bone.
Researchers have developed a novel approach that has resulted in the discovery of a natural compound that acts as a male contraceptive agent.
WEHI researchers have uncovered a process cells use to fight off infection and cancer that could pave the way for precision cancer immunotherapy treatment.
Plants grow in two directions: the shoots of plants grow toward the light to make the best use of it, and the roots grow toward the center of the earth into the soil.
The mechanism through which cytokinin—a plant hormone—regulates the division of cells has been identified.
In this interview, AZoLifeSciences speaks to Dr. Christophe Corre about his latest research that investigated soil bacteria and how it could be used to produce antibiotics.
The research team that developed a biosensor that first recorded that a distinct gradient of the plant growth hormone gibberellin correlated with plant cell size has now revealed how this distribution pattern is created in roots.
A commercially available genomic test may help oncologists better determine which patients with recurrent prostate cancer may benefit from hormone therapy, according to new research from the Johns Hopkins Kimmel Cancer Center and 15 other medical centers.
Even the larvae of the Drosophila fly contain adult progenitor cells. And these cells are the only ones that are preserved throughout the growth and are responsible for the development of adult tissues and organs.
Hormone-mimicking molecules that trigger the production of antibiotics in soil bacteria could present new opportunities for drugs that are right under our feet.
It takes a lot to make a wooden table. Grow a tree, cut it down, transport it, mill it ... you get the point. It's a decades-long process. Luis Fernando Velásquez-García suggests a simpler solution: "If you want a table, then you should just grow a table."
