PBX1 antisense RNA 1 (PBX1-AS1)

PBX1 antisense RNA 1 (PBX1-AS1) is a human long non-coding RNA gene located antisense to the PBX1 gene[5]. PBX1-AS1 does not encode a protein but may regulate the expression of PBX1, a homeobox transcription factor involved in diverse developmental processes and oncogenesis[1][3][5]. While PBX1 itself is a therapeutic target in cancer and immune diseases[7], PBX1-AS1 is studied primarily for its role in post-transcriptional gene regulation and its potential involvement in cancer biology. There is no current evidence that PBX1-AS1 has direct receptor, enzyme, or transporter activity, nor any approved or investigational drugs directly targeting it. Research on PBX1-AS1 mainly focuses on its regulatory effect on PBX1 expression and its possible association with disease processes, particularly cancer.

PBX1-AS1

Not applicable; as PBX1-AS1 is a non-coding RNA, it does not possess binding sites or enzymatic activity typical of drug targets. Any therapeutic targeting would be at the RNA level (e.g., antisense oligonucleotides or RNAi to modulate its expression).
