Apoptosis inhibition in T-cell acute lymphoblastic leukemia by<i> UNC13B</i>

T-cell acute lymphoblastic leukemia is a type of leukemia that is difficult to treat and has a complex pathogen-esis, with no effective treatment currently available. This research group found that the mRNA expression of a new gene, UNC13B, was increased in T-cell acute lymphoblastic leukemia patients. Subsequently, we used T-cell acute lymphoblastic leukemia Jurkat cells to study the mechanism of UNC13B. We constructed a lentivi-IP: 203.8.109.20 On: Thu, 20 Oct 2022 06:54:59 ral vector expressing siRNA to target UNC13B and transfected it into the T-cell acute lymphoblastic leukemiaCopyright: A ic n Sci ntific Publishers Delive ed by Ingenta Jurkat cell line. Using CCK-8, flow cytometry, and western blotting analyses, we found that knockdown of UNC13B inhibited the growth of T-cell acute lymphoblastic leukemia Jurkat cells via the downregulation of signaling proteins of the cell proliferation pathway and upregulation of apoptosis signaling proteins. Based on the bioinformatics analysis results, we found that the mechanism of UNC13B responsible for promoting the growth of T-cell acute lymphoblastic leukemia can be experimentally achieved by triggering AK2, MAP3K7, and PINK1. This study demonstrates that UNC13B is a new potential target for T-cell acute lymphoblastic leukemia.
