These clusters encompass the following themes: “lung cancer,” “tumor microenvironment,” “lung-cancer,” “NSCLC,” “circulating triglycerides,” “transforming growth factor-beta (TGF-β),” and “drug resistance.” To elucidate the chronological progression of keywords, a timeline graph was utilized, resulting in the identification of six distinct natural clusters of keywords (Figure 3B). The gene discussed is TGFB1; the disease is lung carcinoma.
