HIF1A and colorectal cancer: Methods: In this study, our search strategy employed in databases such as PubMed, Web of Science, and EMBASE is as follows: we will specify search terms, including combinations of “non-coding RNA”, “HIF-1α”, and “colorectal cancer”, along with a date range for the literature search (for example, from 2000 to 2025) to capture the most relevant and up-to-date research.
