Introduction
"In the United States, lung and bronchus cancers are the second most common types of cancer diagnosed, with an estimated 228,820 new cases in 2020, representing 12.7% of all newly diagnosed cancer cases [1]. Of these cases, 80-85% are non-small cell lung cancer (NSCLC), including adenocarcinoma, squamous cell carcinoma, and large cell carcinoma subtypes [2]. Lung and bronchus cancers are responsible for the largest number of deaths from cancer, accounting for an estimated 135,720 deaths in 2020, representing 22.4% of all cancer deaths [1]. Significant racial disparities are observed in lung cancer diagnoses and deaths, with African Americans (AAs) receiving a diagnosis of lung cancer three years younger on average than European Americans (EAs), and AAs having the highest number of deaths per 100,000 persons for lung and bronchus cancer [1,3] ."......
......"Given the disproportionate burden of lung cancer within the AA community, the limited exploration of molecular mechanisms underlying lung cancer in patients of African ancestry to date, and the small number of available precision interventions, we highlight efforts to identify, functionally characterize, and modulate novel ancestry-related RNA splicing-related targets in NSCLC for precision intervention."......
.....Biomarkers -
"RNA splice variants can serve as biomarkers for cancer detection. An example is b-variant CDKN1A Interacting Zinc Finger Protein 1 (CIZ1). CIZ1 is a nuclear matrix protein that cooperates with Cyclin A2 and Cyclin Dependent Kinase 2 (CDK2) to promote mammalian DNA replication [36]. It is also needed for recruiting Cyclin A and Cyclin E, and thus also plays a role in S-phase transition [37,38]. In vitro suppression of b-variant CIZ1 has been reported to inhibit NSCLC cell proliferation [39]. b-variant CIZ1 has been shown to be present in lung tumors, but not adjacent tissue, and in plasma from lung cancer patients [39,40]."
