High-Accuracy DNA Methylation Clocks Illuminate Age-Related Changes in Primate Ovaries

The ovary is an essential organ for female fertility, and its age-dependent decline in function is a major cause of infertility.

First Single-Cell Atlas for the Water Nymph Worm Published

An international team of scientists including B. Duygu Özpolat at Washington University in St. Louis has published the first single-cell atlas for Pristina leidyi (Pristina), the water nymph worm, a segmented annelid with extraordinary regenerative abilities that has fascinated biologists for more than a century.

Cellular Atlas of the Human Ovary Offers Hope for Restoring Hormone Production and Fertility

A new "atlas" of the human ovary provides insights that could lead to treatments restoring ovarian hormone production and the ability to have biologically related children, according to University of Michigan engineers.

New Study Unveils Mechanism Behind Mice Ovary Development

Scientists at the Francis Crick Institute have provided insight into the proteins governing the development of mice's ovaries both prenatally and postnatally. This might help comprehend the progression of female infertility.

The Factors Influencing Egg Cell Development

According to a study published in the Proceedings of the National Academy of Sciences, Northwestern Medicine scientists discovered how cytoskeletal proteins influence the growth of developing eggs in fruit flies, findings that advance the field’s understanding of how egg cells form and distinguish themselves from other sister cells.

Study Finds Place of Transcription Start Often Determines the Place of Transcription End

Each gene in the human DNA has a start and an endpoint. It is critical to correctly define the gene's extremities to make functional proteins. Much study has been conducted to identify what determines when, where, and at which place on the DNA a gene “starts.”

The Relation Between an Autism Gene and Infertility

The biological foundations of a reproductive disease caused by a DNA mutation have been discovered by a University of California, Riverside study. Fragile X Syndrome, a major genetic contributor to cerebral impairment and autism, is also caused by this gene mutation.

Decreased viral infection severity in females linked to extra copy of epigenetic regulator

It has long been known that viral infections can be more severe in males than females, but the question as to why has remained a mystery – until possibly now.

Women over 50 with genetic BRCA1 or BRCA2 mutation face a high risk of cancer

Although genetic mutations in BRCA1 or BRCA2 are associated with a younger onset of breast and ovarian cancer, women with these genetic mutations continue to face a high risk of cancer incidence after age 50, even if they have not been previously diagnosed with cancer.

Robust method for induced pluripotent stem cell culture

Different types of cells, such as the heart, liver, blood, and sperm cells, have characteristics that help them perform their specific functions in the body. In general, those traits are hard-wired. A heart cell will not randomly transform into a liver cell if not stimulated.

Study sheds light on unique processes that bestow naked mole-rats’ with eternal fertility

Unlike humans and other mammals, which become less fertile with age, naked mole-rats can reproduce throughout their remarkably long lifespans.

Novel model system helps studying human ovarian biology

Despite the fact that we all start out as an egg cell in one of our mother's ovaries, these human reproductive organs are surprisingly under-studied. Scientists have been working on creating in vitro models of human ovaries so that we can learn more about them and develop treatments for ovarian conditions, but most existing models use a combination of human and mouse cells, which do not faithfully replicate human ovary functions and take a long time to grow in the lab.

New molecular profile of endometriosis to help improve therapeutic options

At Cedars-Sinai, a special and elaborate molecular profile of endometriosis has been engineered by investigators to help enhance therapeutic options for the millions of women suffering from the disease.

Puffer fish use non-toxic version of a powerful neurotoxin to communicate with each other

A delicacy in Japanese cuisine, puffer fish (fugu) also contain a lethal toxin. Improperly prepared puffer fish can cause the person eating it to experience food poisoning and a swift death.

Rumen-protected lysine improves uterine health

Boosting milk yield when included in the diet at sufficient levels, lysine is an important amino acid for dairy cows. But how could lysine be advantageous for cows in other means? A new study by the University of Illinois reveals that rumen-protected lysine can enhance uterine health if given in the transition period.
