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 […]

Fish give insight on sound sensitivity in autism

A tiny fish is helping scientists understand how the human brain processes sound, while also giving insight to autism spectrum disorder. Scientists at The University of Queensland used zebrafish that carry the same genetic mutations as humans with Fragile X syndrome and autism, and discovered the neural networks and pathways that produce […]

Mid-levels of immune marker at birth may protect against autism

Researchers at Karolinska Institutet have investigated the association between certain immune markers in neonates and the risk of later developing autism spectrum disorder (ASD). They found that mid-levels of a classical marker of inflammation, C-reactive protein, were associated with the lowest risk for ASD – whereas too much or not […]

Making cancer cells more susceptible to dying

Radiation and chemotherapy are designed to kill cancer cells. But for many patients, cancer cells can survive even after being hit with high doses of chemotherapy or radiation. To make treatment more effective, scientists are focusing on ways to tweak the inner machinery of cancer cells to make them more […]

Chemicals in your living room cause diabetes

A new UC Riverside study shows flame retardants found in nearly every American home cause mice to give birth to offspring that become diabetic. These flame retardants, called PBDEs, have been associated with diabetes in adult humans. This study demonstrates that PBDEs cause diabetes in mice only exposed to the […]

New immunotherapy launches a two-pronged attack against cancer

Cancer affects millions and millions of people every year. Scientists would like to encourage our own immune system to attack it, which is why immunotherapies are probably the most promising treatments for cancer. Now scientists at UCL developed a new kind of immunotherapy, which launches a two-pronged attack against melanoma, […]
