Epithelial cells, which line the surfaces of the body, are fixed in place, while mesenchymal cells, which make up the body’s connective tissue, are loosely packed and can move around. During embryonic development and wound healing, cells can transform from epithelial cells into mesenchymal cells, a process known as mesenchymal transformation (MT). Unfortunately, MT is also a useful strategy for cancer cells, whose goal is to spread throughout the body.
Since the Food and Drug Administration approved the targeted therapy drug venetoclax in 2020, it has become a first-line treatment for acute myeloid leukemia (AML), a blood cancer. Unfortunately, some AMLs have proven resistant to venetoclax—including those caused by mutations in the RAS gene family, which account for 10-20% of all cases.
In 2022, the FDA approved the first therapy to target human leukocyte antigen (HLA), which has been implicated in a variety of cancers. (The approved drug, tebentafusp, treats uveal melanoma, an eye cancer.) Last year, another HLA-targeted therapy received FDA approval for the treatment of a sarcoma. There are now a plethora of clinical trials open to patients who are HLA-positive.
Enteroendocrine cells, which line the wall of the gut, secrete hormones that regulate glucose levels, food intake, and stomach emptying. Abnormal activity of these cells can cause gastrointestinal disorders, such as irritable bowel syndrome (IBS), as well as intestinal tumors.
Kheewoong Baek, PhD, of Dana-Farber Cancer Institute, has been named this year’s Damon Runyon-Meghan E. Raveis Fellow. This award honors former Damon Runyon Board Member Meghan Raveis, who tragically passed in a car accident in 2023.
Translocation renal cell carcinoma (tRCC) is a type of kidney cancer that arises when a gene called TFE3 on the X chromosome fuses with another gene on either the X chromosome or an autosome, as non-sex chromosomes are called. Unlike most kidney cancers, tRCC occurs mainly in female individuals, though why this is the case has never been clear. Now, a new study from Damon Runyon-Rachleff Innovator Srinivas R.
Patients with kidney disease who are undergoing dialysis often need to take a drug called a calcium-sensing receptor (CaSR) agonist to regain normal calcium levels in their blood. Unfortunately, inhibiting CaSR can sometimes reduce calcium levels too much, resulting in a condition known as hypocalcemia that carries serious adverse side effects. A major question in pharmacology, then, is how to modulate CaSR activity such that patients receive the benefits and not the risks.
