Understanding how long non-coding RNAs control gene expression in cancer

Long non-coding RNAs (lncRNA) are a type of RNA molecule that do not carry instructions to make proteins. Instead, they influence how other genes are expressed.

Researchers discover amyloid protein buildup in bone marrow of aging mice

A recent study led by a team of researchers at The Johns Hopkins University School of Medicine examining aging mice has provided what is believed to be the first evidence that amyloid beta protein-small, sticky protein fragment found in people with Alzheimer's disease (AD)-particles build up in the bone marrow of the animals, although not in the exact same form as the large, dense plaques found in the brains of people with Alzheimer's disease.

New initiative expands screening for cardiovascular disease marker in community health centers

Elevated lipoprotein(a), also known as Lp(a), is an independent, inherited and causal risk factor for cardiovascular disease, the leading cause of death and disability worldwide.

Lipid droplet protein perilipin 2 linked to poor prognosis in lung cancer

New research has revealed that perilipin 2 protein modulates aggressive cancer progression in advanced lung adenocarcinoma, the most common type of lung cancer, by regulating lipid droplet accumulation, which plays an important role in lipid metabolism by making cancer cells store more fat, acting as a fuel source.

Timing of sexual history influences partner choice across cultures

A major international study has found that when it comes to choosing a long-term partner, people across the globe consider not just how many sexual partners someone has had, but also when those encounters took place.

'Two-in-one' RNA molecule can simultaneously turn off two difficult-to-target cancer-related genes

University of North Carolina Lineberger Comprehensive Cancer Center researchers have developed a "two-in-one" molecule that can simultaneously turn off two notoriously difficult-to-target cancer-related genes, KRAS and MYC, as well as directly deliver drugs to tumors that express these genes.

New treatment approach developed to prevent lupus nephritis

At the time when patients with lupus, or systemic lupus erythematosus (SLE), are diagnosed, approximately 15% to 30% will already have the inflammation-caused kidney disease lupus nephritis, which compromises kidney function and can lead to kidney failure.
