Hormone News and Research

RSS

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.

More informed choices of contraceptives can prevent breast cancer

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.

Breast cancer survivors have higher risk of new cancer diagnosis compared to healthy individuals

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.

Mutant corn gene found to increase the amount of sugars in the seeds and leaves

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.

New, altered form of prolactin receptor found to drive breast cancer

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.

SDIR1 enzyme plays a major role in the expression of defense gene in plants

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.

Study shows how stem cells make specific types of cells

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.

Dopamine-releasing brain cells shed light on Parkinson’s disease

Scientists have found that botulinum toxin—commonly known as Botox—can expose the inner workings of the brain, in addition to smoothing out wrinkles.

Stem cell therapy could help restore debilitating muscle loss that happens with age

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 may help disarm coronavirus spike protein and stop disease progression

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.

Lowering apolipoprotein CIII levels can prevent deleterious effects of a high-fat diet

Consumption of a diet with high fat levels increases the risk of fatty liver, obesity, cardiovascular diseases, and type 2 diabetes.

Researchers generate thyroid mini-organs in the lab

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.

Vegan diet leads to poorer bone health, shows study

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.

Natural compound acts as reversible male contraceptive pill

Researchers have developed a novel approach that has resulted in the discovery of a natural compound that acts as a male contraceptive agent.

Research provides new insight into the way cells adapt to fight infection

WEHI researchers have uncovered a process cells use to fight off infection and cancer that could pave the way for precision cancer immunotherapy treatment.

Study describes molecular mechanisms of polar growth in plants

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.

Study reveals mechanism through which plant hormone controls cell division

The mechanism through which cytokinin—a plant hormone—regulates the division of cells has been identified.

Using soil bacteria for antibiotic production

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.

Researchers combine maths and plant science to reveal how plant roots produce a hormone gradient

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.

Genomic test helps identify prostate cancer patients who may benefit from hormone therapy

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.

Researchers identify tumor suppressor gene involved in stress response

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.
