Hypoxia pathway–related mRNAs (Hypoxia mRNAs)

Hypoxia pathway–related mRNAs represent a collective group of messenger RNA transcripts that encode proteins essential for the cellular response to low oxygen environments. The primary drivers of this pathway are the Hypoxia-Inducible Factors (HIFs), specifically HIF-1α and HIF-2α, which regulate the transcription of genes involved in angiogenesis (e.g., VEGFA), metabolic reprogramming (e.g., GLUT1), and cell survival. In many solid tumors, these mRNAs are overexpressed, allowing cancer cells to adapt to hypoxic microenvironments, promote blood vessel growth, and resist radiotherapy or chemotherapy. Therapeutic strategies targeting these mRNAs typically utilize antisense oligonucleotides (ASOs) or siRNA to silence the expression of the pathway at the pre-translational level. While promising for treating hypervascularized tumors and retinal diseases, this approach is considered a broad target category rather than a single molecular entity, often requiring specific focus on individual transcripts like HIF1A or VEGFA for clinical development.

Antisense oligonucleotides (ASOs) or small interfering RNAs (siRNAs) bind to specific hypoxia-related mRNA sequences to induce degradation via RNase H or the RNA-induced silencing complex (RISC), thereby preventing the translation of pro-angiogenic and pro-survival proteins like HIF-1α or VEGF.
