Treatment options for triple-negative breast cancer (TNBC) are limited due to the lack of efficient targeted therapies, frequently resulting in recurrence and metastatic disease. Accumulating evidence suggests that a small population of cancer stem-like cells (CSLCs) is responsible for...

B-cell acute lymphocytic leukemia (B-ALL), a common blood cancer in children, leads to high mortality. Cyclin-dependent kinase 9 inhibitor (CDK9i) effectively attenuates acute myeloid leukemia and chronic lymphoblastic leukemia by inducing apoptosis and inhibiting cell proliferation. However, the effect...

Osteoarthritis and cartilage

Fukui T, Yik JHN, Doyran B, Davis J, Haudenschild AK, Adamopoulos IE, Han L, Haudenschild DR.
PMID: 33164842
Osteoarthritis Cartilage. 2021 Jan;29(1):68-77. doi: 10.1016/j.joca.2020.07.012. Epub 2020 Oct 23.

OBJECTIVE: Joint injury rapidly induces expression of primary response genes (PRGs), which activate a cascade of secondary genes that destroy joint tissues and initiate post-traumatic osteoarthritis (PTOA). Bromodomain-containing-protein-4 (Brd4) and cyclin-dependent-kinase-9 (CDK9) cooperatively control the rate-limiting step of PRG...
