Study reveals new role for a triple-negative breast cancer target

Unlike almost every other organ, the mammary gland does not develop until after birth. And it's unusually dynamic, shape-shifting during menstrual cycles, puberty, pregnancy, and lactation.

Different mutations in a single gene can have myriad effects on a person's health

Mount Sinai researchers have found that different mutations in a single gene can have myriad effects on a person's health, suggesting that gene therapies may need to do more than just replenish the missing or dysfunctional protein the gene is supposed to encode, according to a study published in Nature Genetics in November.

Researchers identify frequent technical bias in data generated by RNA-seq technology

Reproducibility of research data is a major challenge in experimental biology. As data generated by genomic-scale techniques increases in complexity, this concern is becoming more and more worrisome.

Researchers identify novel genetic signature with prognostic value for certain breast cancers

Researchers have identified a genetic signature with prognostic value for certain kinds of breast cancer. The discovery also contributes to a better understanding of the molecular mechanisms of pathological angiogenesis, the aberrant proliferation of blood vessels that occurs during cancer and other diseases.

Brazilian researchers create hepatic organoids by 3D bioprinting

Using human blood cells, Brazilian researchers have succeeded in obtaining hepatic organoids ("mini-livers") that perform all of the liver's typical functions, such as producing vital proteins, storing vitamins, and secreting bile, among many others.

Using bacterial nano-syringes as drug transporters in medicine

Pathogens can use a range of toxins to damage their host organism. Bacteria, such as those responsible for causing the deadly Plague, use a special injection mechanism to deliver their poisonous contents into the host cell.

Research finds key reason why brain connectivity goes awry in rare neurodevelopmental conditions

Axons are the long thread-like extensions of neurons that send electrical signals to other brain cells. Thanks to axonal connectivity, our brains and bodies can do all necessary tasks.

New concepts for efficient, reliable risk assessment of nanomaterials

From dyes to construction materials, and from cosmetic products to electronics and medicine, nanomaterials are found in many different applications. But what are these materials? "Nanomaterials are defined purely by their size," explains Dr Kristin Schubert from the Department of Molecular Systems Biology at UFZ.

Salk researchers uncover new function of mitochondria

Mitochondria, tiny structures present in most cells, are known for their energy-generating machinery. Now, Salk researchers have discovered a new function of mitochondria: they set off molecular alarms when cells are exposed to stress or chemicals that can damage DNA, such as chemotherapy.

New techniques could help neuroscientists track brain computations

Since the 1950s at least, researchers have speculated that the brain is a kind of computer in which neurons make up complex circuits that perform untold numbers of calculations every second. Decades later, neuroscientists know that these brain circuits exist, yet technical limitations have kept most details of their computations out of reach.
