https://www.selleckchem.com/products/pkr-in-c16.html GNA13, encoding one of the G protein alpha subunits of heterotrimeric G proteins that transduce signals of G protein-coupled receptors (GPCR), is frequently mutated in germinal center B-cell-like diffuse large B-cell lymphoma (GCB-DLBCL) with poor prognostic outcomes. Due to the "undruggable" nature of GNA13, targeted therapy for these patients is not available. In this study, we found that palmitoylation of GNA13 not only regulates its plasma membrane localization, but also regulates GNA13's stability. It is essential for the tumor suppressor function of GNA13 in GCB-DLBCL cells. Interestingly, GNA13 negatively regulates BCL2 expression in GCB-DLBCL cells in a palmitoylation-dependent manner. Consistently, BCL2 inhibitors were found to be effective in killing GNA13-deficient GCB-DLBCL cells in a cell-based chemical screen. Furthermore, we demonstrate that inactivating GNA13 by targeting its palmitoylation enhanced the sensitivity of GCB-DLBCL to the BCL2 inhibitor. These studies indicate that the loss-of-function mutation of GNA13 is a biomarker for BCL2 inhibitor therapy of GCB-DLBCL and that GNA13 palmitoylation is a potential target for combination therapy with BCL2 inhibitors to treat GCB-DLBCL with wild-type GNA13. To compare visual improvements between initial intravitreal t-PA with gas injection before anti-vascular endothelial growth factor (VEGF) and anti-VEGF injection monotherapy for submacular haemorrhage (SMH) associated with age-related macular degeneration (AMD). We retrospectively reviewed medical records of naive patients treated with intravitreal t-PA with gas injection before anti-VEGF (Group 1) or only with intravitreal anti-VEGF injection (Group 2) for SMH [disc area (DA) ≥ 2] associated with AMD from two institutions. Both groups received 3 monthly loads of anti-VEGF injections followed by injections as needed for AMD treatment. Changes in best-corrected visual acuity (BCVA, logMAR) between
