Summary

Caution, this is an AI generated summary based on literature. This may have errors.

MIR944 is a microRNA that has been identified as overexpressed in patients with non-small cell lung cancer (NSCLC) relative to healthy controls, with a more than fourfold increase in expression [PMC5627048]. It has been implicated in modulating sensitivity to chemotherapy in solid tumors [PMC8602334]. The MIR944 promoter is transcriptionally regulated by ΔNp63, particularly during keratinocyte differentiation, with ΔNp63 binding to the promoter maintained during this process [PMC4551945]. Co-regulators such as TFAP2A and TFAP2C have been identified as supporting the binding of ΔNp63 to the MIR944 promoter, suggesting a complex regulatory mechanism that maintains miR-944 expression during epidermal differentiation [PMC4551945]. The chromatin architecture of the MIR944 genomic region is open in keratinocytes, facilitating transcription initiation [PMC4551945]. Conservation analyses indicate that MIR944 is evolutionarily young and primate-specific, suggesting its recent emergence and potential specialized function in these species [PMC4551945]. Overall, MIR944 appears to be an important regulatory miRNA with its own promoter within the intron of ΔNp63 and may play a role in epidermal differentiation and cancer biology [PMC4551945][PMC6510770[PMC6510770].
