Fanconi anemia proteins participate in a break-induced-replication-like pathway to counter replication stress.

Nat Struct Mol Biol 2021 Jun 10;28(6):487-500. Epub 2021 Jun 10.

State Key Laboratory of Protein and Plant Gene Research, School of Life Sciences, Peking University, Beijing, China.

Fanconi anemia (FA) is a devastating hereditary disease characterized by bone marrow failure (BMF) and acute myeloid leukemia (AML). As FA-deficient cells are hypersensitive to DNA interstrand crosslinks (ICLs), ICLs are widely assumed to be the lesions responsible for FA symptoms. Here, we show that FA-mutated cells are hypersensitive to persistent replication stress and that FA proteins play a role in the break-induced-replication (BIR)-like pathway for fork restart.

A Review of Romiplostim Mechanism of Action and Clinical Applicability.

Drug Des Devel Ther 2021 26;15:2243-2268. Epub 2021 May 26.

Division of Hematology and Transfusion Medicine, Lund University, Lund, Sweden.

Thrombocytopenia results from a variety of conditions, including radiation, chemotherapy, autoimmune disease, bone marrow disorders, pathologic conditions associated with surgical procedures, hematopoietic stem cell transplant (HSCT), and hematologic disorders associated with severe aplastic anemia. Immune thrombocytopenia (ITP) is caused by immune reactions that accelerate destruction and reduce production of platelets. Thrombopoietin (TPO) is a critical component of platelet production pathways, and TPO receptor agonists (TPO-RAs) are important for the management of ITP by increasing platelet production and reducing the need for other treatments.
