Checkpoints and immunity in cancers: Role of GNG12

Cancer progression is enhanced through cell proliferation, with the crucial role of the transducer and transmembrane –signal regulator (GNG12) bringing it to the fore. Dysregulation of cancer cell metabolism, evasion of the immune system, cell cycle, apoptosis, and chemoresistance result from inconsistent initiation of the NF-kB signaling pathway. We excerpt from previous studies that overactivation of the canonic NF-kB cascade occurs in varieties of tumor cells, which results in the growth of lymphovascular invasion, as well as neural invasion. Recently, research has adduced that a particular G protein- coupled receptor (GNG12) is silently involved in the activation of the NF-kB signal, which supports the evasion of cancer immunity and in turn activates cancer proliferation, angiogenesis, and immunotherapeutic resistance. While the likely impact of GNG12 in relation to the progression of tumors is being established, there is insufficient knowledge regarding the functions and mechanisms of GNG12 in cancer immunity. Furthermore, the cancer-associated role as well as the clinical correlation of GNG12 have long been unknown; thus, their identification is more likely to pave the path for a novel regime of tumor suppression. In this study, we established the silent role of GNG12 in activating NF-kB genes and the synergism between NF-kB and PD-L1 expression. Captivatingly, we reported that silencing GNG12 gene downregulates the transcription of PD-L1 gene. We therefore suggested that GNG12 is a risk factor for several cancers, and a possible target for immunotherapy.
