More than 100M cells included in the human cell atlas

Nov. 21, 2024
By Mar de Miguel
An international consortium of thousands of scientists is creating the Human Cell Atlas, a three-dimensional map of all the cells in the body. The goal is to understand all the cells that make up human tissues, organs and systems, which will enable multiple medical applications. This collection of cell maps is openly available for navigation at single-cell resolution, identified through omics analyses that reveal the tridimensional distribution of each cell.

Holistic strategies needed to diagnose and treat endometriosis

Nov. 19, 2024
By Tamra Sami
Endometriosis has been woefully under-recognized in the medical community, and consequently, the delay between onset and diagnosis is often quite long, with some women waiting up to 12 years for a diagnosis.

The science of gender-based medicine: many reasons, many manifestations

Nov. 14, 2024
By Anette Breindl
At the BioFuture 2024 conference held in New York in November, Seema Kumar, the CEO of Cure, described women’s health as something that has been directed at the “bikini area.” That “bikini” bias extended to both diseases and their causes – women’s health covered the breasts and reproductive system, and its causes were hormonal. Both concepts are far too narrow.

Healing a health divide (that’s long overdue)

Nov. 14, 2024
By Lynn Yoffee
It’s difficult to fathom that the health of half the world’s population is underserved. But it’s a hard truth. There are many conditions that disproportionately impact women. Other conditions and diseases affect women in different ways than men. Decades of research excluding women from clinical trials and investment decisions in male-dominated board rooms have ignored these facts. Though an increasing number of women are now managing investments and driving the research, it’s all still woefully behind. In BioWorld’s new report, Healing the health divide, we’ve highlighted the disparities.

Extrachromosomal DNA acts as joker for cancer cells

Nov. 13, 2024
By Mar de Miguel
Cancer therapies can eliminate specific tumors based on their genetic content. However, some cancer cells survive. How do they do it? Part of the answer lies in extrachromosomal DNA (ecDNA), an ace up the tumors’ sleeve to adapt and evade attack. Three simultaneous studies in the journal Nature lay all the cards on the table, revealing ecDNAs’ content, their origin, their inheritance, their influence in cancer, and a way to combat them.

Quiescent, but not quiet, cancer stem cells in glioblastoma relapse

Nov. 13, 2024
By Mar de Miguel
Six main cell types form glioblastomas, the most aggressive brain cancer due to its high rate of recurrence. Of these six, quiescent cancer stem cells are responsible for resistance to therapy and the reappearance of the tumor, according to a study that identified the six groups and highlighted the importance of these stem cells for the design of more effective therapies.

Less microglia activity may improve APOE4’s effect in Alzheimer’s

Nov. 8, 2024
By Mar de Miguel
Reducing microglial activity in the presence of apolipoprotein E4 (APOE4) has uncovered a mechanism associated with the deposition of misfolded amyloid and tau in a novel mouse model of Alzheimer’s disease. By transplanting human neurons into the mouse brain and eliminating the mouse microglia, scientists at the Gladstone Institutes in San Francisco observed that amyloid and tau deposition was reduced. These results support therapeutic strategies that target APOE4 and microglia.

Blocking CGRP in endometriosis: two birds with one stone?

Nov. 7, 2024
By Coia Dulsat
Researchers at Harvard Medical School have found that blocking the neuron-released peptide CGRP decreases pain sensitivity and reduces lesion size in endometriosis. Endometriosis is a painful, steroid-dependent inflammatory condition in which tissue similar to that of the endometrial lining grows and establishes outside the uterine mucosa.

Gene editing is Trojan horse of cancer immunotherapy

Nov. 4, 2024
By Mar de Miguel
Gene editing strategies, from epigenetic engineering to cell reprogramming and genetic vaccines, are accelerating the development of new therapies that awaken the immune system to treat cancer, as presented last month in Rome at the 31st Annual Congress of the European Society of Gene and Cell Therapy (ESGCT). Some of these advances are taking advantage of the conditions of the tumor microenvironment, where cancer cells coexist with immune cells, microorganisms and blood vessels.
