Abstract: Inhibition of apoptosis is a prominent feature of hematological malignancies.B-cell lymphoma-2(BCL-2)is a key protein regulator of apoptosis and is expressed to varying degrees in a variety of hematological malignancies.The anti-apoptotic ability of tumor cells with high expression of BCL-2 is significantly enhanced,and targeted inhibition of BCL-2 has become one of the research hotspots in anti-hematological tumors.Venetoclax(VEN)is the first BCL-2 inhibitor(BCL-2i)approved for the treatment of chronic lymphocytic leukemia,acute myeloid leukemia and myelodysplastic syndromes.Studies have shown that VEN also has antitumor activity against other hematological malignancies such as B-cell non-Hodgkin lymphomas and multiple myeloma.This article briefly reviews the anti-apoptosis mechanism of BCL-2,the clinical application of BCL-2i in hematological malignancies,and the possible mechanism of BCL-2i resistance.

Key words: B-cell lymphoma-2, Apoptosis, Venetoclax, Hematological malignancies
