Sugar work: U-M study finds sugar remodels molecular memory in fruit flies

A high-sugar diet reprograms the taste cells in fruit flies, dulling their sensitivity to sugar and leaving a “molecular memory” on their tongues, according to a University of Michigan study. Examining fruit flies, researchers Monica Dus, Anoumid Vaziri and collaborators found that high-sugar diets completely remodelled the flies’ taste cells, […]

Cellular Survivors

When it comes to complex life — that of the multicellular variety — cell death can be just as important as survival. It allows organisms to clean house and prevent the proliferation of damaged cells that could compromise tissue function. Several years ago, biologist Denise Montell, a distinguished professor at UC […]

Penn Researchers Discover Two Key Events That Turn Normal Cells into Cancer

More than 100 different cancers can arise all over the body, but two universal metabolic pathways may tie them all together, researchers from the Perelman School of Medicine at the University of Pennsylvania report in a new study published online in Cell Metabolism. Researchers have long believed all cancers are […]

A new test for chronic fatique syndrome

Developed by researchers at UdeM and the CHU Sainte-Justine, the innovation allows testing of patients who cannot participate in clinical studies due to the severity of their condition. Myalgic encephalomyelitis (ME), better known as chronic fatigue syndrome, is a complex chronic disease affecting some 600,000 Canadians and up to 2.5 […]

Molecular atlases reveal how human cells develop and grow

UW Medicine researchers at the Brotman Baty Institute in Seattle have created two cell atlases that track gene expression and chromatin accessibility during the development of human cell types and tissues. One atlas maps gene expression within individual cells across 15 fetal tissues. The second atlas maps the chromatin accessibility […]

Detecting Alzheimer’s disease before symptoms arise

Both of Andrew Kiselica’s grandfathers developed dementia when he was in graduate school. As Kiselica was going through neuropsychology training in graduate school, he saw his mother’s father become unable to walk or speak due to severe dementia. The University of Missouri researcher said that personal experience has motivated his work to […]

Gut Bacteria Linked to Weight Gain Following Chemotherapy Treatment for Breast Cancer

Marking Breast Cancer Awareness Month, researchers say they eventually hope to identify women at risk and offer methods to prevent weight gain following chemotherapy. Approximately 30% of breast cancer patients who receive chemotherapy treatment gain weight, though it is unclear why this phenomenon occurs in some women but not in others.  […]

Compounds block stress-enhanced nicotine intake in rats

Stress is a major cause of relapse after people quit smoking. Worrying situations, such as money or relationship problems, can affect neurotransmitter levels in the brain, leading former smokers to reach for a cigarette. Now, researchers reporting in ACS Pharmacology & Translational Science have discovered that compounds that activate γ-aminobutyric acid (GABA) […]

Penn Researchers Identify Specific Genes and Cell Pathways as Key Players in the Rare Female Lung Disease Lymphangioleiomyomatosis (LAM)

Deleting the TSC2 gene in specific lung cells of mice led to the activation of the mTORC1 signalling pathway and pulmonary disease characteristics consistent with human LAM disease, particularly in female breeder mice. These mice without TSC2 also exhibited a dysfunctional WNT cellular signalling pathway, which is also tied to lung […]

pH-sensitive iridium complexes as catalytic anticancer compounds

IMDEA Nanociencia researchers present a new family of organometallic iridium complexes that generate cytotoxicity only upon intracellular activation. Chemotherapy is defined as the use of chemicals to reach and damage cancer cells. On its way towards the tumour, the drugs can affect healthy cells as well. For example, cisplatin, a […]

No, your birth control won’t cause depression

Study debunks common myth that hormonal contraceptives cause depression, suicide in women. Women who struggle with mental illness often don’t take the most effective birth control methods because they worry the hormones in these contraceptives can trigger depression and suicide, a myth that has been perpetuated by recent studies. A […]

Study discovers potential target for treating aggressive cancer cells

As researchers and medical professionals work to develop new treatments for cancer, they face a variety of challenges. One is intratumor heterogeneity — the presence of multiple kinds of cancer cells within the same tumor. Often, these “mosaic” tumors include cells, such as polyploidal giant cancer cells, that have evolved […]
