Characteristics

HNF1A-AS1 is a 2455-nucleotide single-exon gene located at chromosomal band 12q24.31 and it is also a bidirectional IncRNA corresponding to the hepatic nuclear factor 1 alpha gene (HNF1A, also known as transcription factor 1 or TCF1), whose transcriptional start site occurs approximately 5 kb 5′ to that of HNF1A-AS1 [1].

Function

HNF1A-AS1 is associated with the promotion of EAC cell proliferation and anchorage-independent growth,and is also correlated with promotion of EAC cell migration and/or invasion [1]. HNF1A-AS1-mediated promotion of EAC cell proliferation and survival appears to be mediated by modulation of the G1-S checkpoint rather than by apoptosis and this process may involve chromatin/nucleosome assembly [1].

Regulation

H19 may represent an important downstream effector of HNF1A-AS1, potentially mediating this IncRNA’s effects on tumour growth [1].

Evolution

HNF1A-AS1 is evolutionally poorly conserved , yet widely expressed in the aerodigestive tract [1].

Expression

There is a significant positive correlation between HNF1A-AS1 and H19 expression in primary EACs [1].

HNF1A-AS1 is significantly up-regulated in lung adenocarcinoma tissues compared with corresponding non-tumor tissues, and its expression level is significantly correlated with TNM stage, tumor size, and lymph node metastasis [2].
