Researchers identify gene expression involved in cancer progression and chemotherapy resistance

Even within a single patient with cancer, there is a vast diversity of individual tumor cells, which display distinct behaviors related to growth, metastasis, and responses to chemotherapy.

Pathway preferential estrogens may be a safer alternative to hormone replacement therapy, study shows

Postmenopausal women have increased risk of non-alcoholic fatty liver disease due to loss of estrogen from metabolic changes. A high-fat diet further exacerbates the disease, which can progress to cirrhosis and liver failure.

New discovery could help better understand how cells migrate during early development

Cells can control their ability to move through the body by using a protein called fascin to control the stiffness of neighboring cells, suggests a study published today in eLife.

Researchers uncover the role of estrogen in exercise

Experts in sex as a biological variable are uncovering the role of estrogen in exercise. The researchers will present their findings virtually at the American Physiological Society's (APS) New Trends in Sex and Gender Medicine conference.

Contraceptive pill can reduce the risk of type 2 diabetes in women with PCOS, study reveals

A study led by the University of Birmingham has revealed for the first time that the contraceptive pill can reduce the risk of type 2 diabetes by over a quarter in women with polycystic ovary syndrome (PCOS).

Researchers identify neurons and signaling pathways that make sexually receptive females more active

Scientists have known for a century that female animals become more active just as they are about to ovulate, a behavior that evolved to enhance their chances of mating when they are fertile.

Existing drug reduces obesity and fatty liver in mice without changes in food intake or daily activity

Researchers at Johns Hopkins Medicine have found that a drug first developed to treat Alzheimer's disease, schizophrenia and sickle cell disease reduces obesity and fatty liver in mice and improves their heart function — without changes in food intake or daily activity.

Young people with cancer face inequalities in fertility preservation services across the UK

Young people who survive cancer are at risk of missing out on the chance to have children in the future, due to inequalities in fertility preservation services across the UK, new research has found.

Liquid biopsies could help identify, track bladder cancer and peripheral nerve tumors

Liquid biopsies detect tumor DNA in blood or urine samples. Two studies led by Washington University School of Medicine in St. Louis describe the potential of liquid biopsies to identify and track tumor growth in two very different cancers: bladder cancer and peripheral nerve tumors.

Can molecular mimicry impact fertility in female COVID-19 patients?

There exists a possibility that COVID-19 can also affect the reproductive function in the body, which can lead to infertility in infected patients. A study published in the American Journal of Reproductive Immunology explored the impact of SARS-CoV-2 infection on reproductive functions and fertility.

Researchers discover how PARP inhibitors selectively kill BRCA-mutant cancer cells

A team of Massachusetts General Hospital researchers has discovered how an important class of anti-cancer drugs called PARP inhibitors works, a finding that could help improve treatment and prolong survival for patients with breast cancer and other malignancies.

Microbe transmitted between mosquitoes could be key to controlling malaria

A microbe that is transmitted between male and female mosquitoes but can also block reproduction could be key to controlling malaria by targeting its release into mosquito populations, a study says.

Knowledge and support from primary care services can improve women's health during menopause

More knowledge and individual support from primary care services can alleviate women's menopausal problems, a University of Gothenburg thesis shows.

Study finds higher risk of pre-eclampsia, hypertension in pregnancies derived from frozen embryos

A large cohort study drawn from the national IVF registry of France, which included almost 70,000 pregnancies delivered after 22 weeks gestation between 2013 and 2018, has found a higher risk of pre-eclampsia and hypertension in pregnancies derived from frozen-thawed embryos.

Higher risk of preeclampsia and pregnancy-induced hypertension as a result of embryo freezing for IVF

Researchers have established a strong association between the risk of developing hypertension and the artificial cycle for frozen-thawed embryo transfer.

Researchers are closer to unraveling the mystery of science behind regeneration

Many salamanders can readily regenerate a lost limb, but adult mammals, including humans, cannot. Why this is the case is a scientific mystery that has fascinated observers of the natural world for thousands of years.

Researchers describe the key facet of sexual determination in mammalian models

Early in human development, during the first trimester of gestation, a fetus may have XX or XY chromosomes that indicate its sex. Yet at this stage a mass of cells known as the bipotential gonad that ultimately develops into either ovaries or testes has yet to commit to its final destiny.
