Meiosis News and Research

RSS

Multicellular eukaryotes and single-celled sex cells reproduce by a process called meiosis. In this process, the number of chromosomes in a mother cell is halved to produce gametes, cells that fuse with other cells. This happens in plants, animals, and fungi. German biologist, Oscar Hertwig first discovered meiosis in sea urchin eggs in 1876.

CPRIT awards $2 million to SMU to recruit cancer biology researcher Annika Wylie

The Cancer Prevention and Research Institute of Texas (CPRIT) has awarded $2 million to recruit Annika Wylie to SMU and fund five years of her research, which focuses on the p53 gene, a naturally occurring tumor suppressor.

Study provides new insights into the mechanism of Dmc1 filament assembly

Homologous recombination (HR) is an important process that plays multiple crucial roles during meiosis, a type of cell cycle dedicated to sexual reproduction.

An analysis of the differential effect and the impact of SARS-CoV-2 infection on semen quality

Study analyzed the impact of SARS-CoV-2 infection on semen quality.

TbID-based proteomic profiling in meiotic cells helps identify proximate proteins in A. thaliana

During meiosis, reshuffling of genetic information between homologous chromosomes through meiotic recombination creates variable gametes and hence genetic variation in offsprings.

Study aims to understand how female fertility is established at the molecular level

Fertility is finite for mammalian females. From birth, females possess a limited number of primordial follicles, collectively called the ovarian reserve. Within each follicle is an oocyte that eventually becomes an egg. But with age, the follicles in the ovarian reserve decrease.

Newly characterized stem cell self-renewal factor enables continuous sperm production

Unlike women, who are born with all the eggs they'll ever have, men can continue to produce sperm throughout their adult lives. To do so, they require a constant renewal of spermatogonial stem cells, which give rise to sperm.

Newly-discovered historical information reveals that Mendel was decades ahead of his time

Gregor Mendel, the Moravian monk, was indeed "decades ahead of his time and truly deserves the title of 'founder of genetics.'" So concludes an international team of scientists as the 200th birthday of Mendel approaches on 20 July.

Study offers a new understanding of the evolutionary diversification of KNL2 gene

In living organisms cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.

Genetically-enhanced biocontrols can help eradicate invasive alien mammals

Invasive alien mammals can have catastrophic impacts on native flora and fauna, causing species extinctions and driving profound environmental change.

Study identifies critical genes and biological pathways related to COVID-19 myocarditis

Scientists from China have recently deciphered the genetic network and biological mechanisms associated with COVID-19 myocarditis using bioinformatic methods.

"Founder events" that reduced genetic diversity found to be common throughout human history

Human populations have waxed and waned over the millennia, with some cultures exploding and migrating to new areas or new continents, others dropping to such low numbers that their genetic diversity plummeted.

Potential new diagnostic marker predicts successful, efficient development of mammalian egg cells

Researchers at the Centre for Genomic Regulation in Barcelona have identified a potential new diagnostic marker that predicts the successful and efficient development of mammalian egg cells.

Penn study shows how certain proteins have evolved to suppress cheating chromosomes

Eggs and sperm are special cells for many reasons, but one of the characteristics that sets them apart is that, unlike other human cells, which have two copies of 23 chromosomes, one from the mother and one from the father, these sex cells, or gametes, have only one.

Study discovers lagging chromosomes as one of the major causes of infertility

Why do women over 35 have more difficulty getting pregnant? After discovering one of the causes of age-related female infertility, researchers at the University of Montreal Hospital Research Centre suggest that it will be possible in the future to improve the quality of the eggs of older patients by intervening on the cell cycle level.
