Study investigates BMI, race, and lung cancer diagnosis relationships

Lung cancer is the leading cause of cancer death in the US, making up 25% of cancer deaths. With obesity rates simultaneously rising, researchers have investigated the connections between cancer risk and body mass index (BMI). Unlike most other cancer types, where higher BMI is associated with increased risk of cancer, research has established that paradoxically people with higher BMI have lower rates of lung cancer diagnosis.

First report of a SARS-CoV-2 variant with an ORF7a deletion that dominated an outbreak

In a recent study posted to the medRxiv* preprint server, researchers in Australia determined whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Delta-ORF7aΔ17del [open reading frame 7a protein with 17-nucleotide (nt) frameshift-inducing deletion] variant has a fitness advantage over the Delta variant lacking the ORF7aΔ17del deletion (Delta-ORF7aintact) and/or the SARS-CoV-2 lineage (A.2.2).

Antibiotics accelerate metastatic bone growth in mice with melanoma by depleting intestinal flora

The use of broad-spectrum antibiotics in mice with malignant melanoma, an aggressive form of skin cancer, accelerated their metastatic bone growth, likely because the drugs depleted the mice's intestinal flora and weakened their immune response, according to a new study by researchers at Emory University in Atlanta.

Blocking FNDC5 prevents cancer-induced cachexia in mice

The severe muscle atrophy and weakness commonly associated with cancer growth (i.e., cachexia) can be prevented simply by being deprived of FNDC5, the precursor of the exercise hormone irisin, researchers from the Indiana University School of Medicine have found.
