Hypoxia-inducible factor (HIF) is a transcription factor that is effective in the ability of cells to sense and adapt to changes in oxygen levels. HIF1A gene is located in the 14q23.2 chromosome region and consists of 15 exons and 14 introns. It is a transcriptional regulator of metabolic processes such as angiogenesis and erythropoiesis and is required for immunological responses. In our study, the function of HIF1A and its relations with other genes and diseases were examined using various bioinformatics database tools. GENEMANIA/GeneCard databases were used to detect the relationship of HIF gene with other genes, miRDB to show target miRNAs, STRING to detect protein-protein interaction, and GWAS databases to show its relationship with diseases. In addition, organs and tissues in which it is expressed were determined using the UniProt database. As a result of bioinformatic analysis, it was shown that HIF1A was targeted by 189 miRNAs and it was found that it interacts closely with 10 genes, including important genes such as STAT3, MDM2, TP53, SMAD3, VHL. It has been determined that the pathway used by the HIF1A gene most effectively is the HIF-1 signaling pathway, and it has been shown that there is a co-expression relationship with EPO, PLIN2, BNIP3 proteins and ENO1 enzyme. In addition, it was determined that HIF1A is most frequently expressed in the kidney and the perivenous region of the liver and also, it has been shown to be closely related to diseases such as renal cell carcinoma, bladder cancer. Identifying the pathways associated with HIF1A, other genes and epigenetic factors with the help of Bioinformatics Tools may enable experimental studies to be carried out with large cohorts and using a broad perspective. Thus, it may contribute to our understanding of how this gene affects diseases and anomalies and to accelerate the studies of targeted therapeutic treatment.
