Overview

Feline leukemia virus subgroup C cellular receptor 1 antisense RNA 1 (FLVCR1-AS1) is a long non-coding RNA (lncRNA) located on chromosome 1q32.3, transcribed antisense to the FLVCR1 gene. It functions as a competing endogenous RNA, sequestering microRNAs (such as miR-30b-3p in glioblastoma or miR-381 in colorectal cancer), leading to derepression of oncogenic targets like E2F2 or RAP2A. Elevated FLVCR1-AS1 expression promotes tumor cell proliferation, migration, sadly, and invasion, and reduces apoptosis. Its aberrant upregulation is associated with poor prognosis in several human cancers, making it a potential therapeutic target and biomarker for cancer diagnosis and patient stratification. Note: Despite the initial user query referencing "FLVCR2-AS1," the information available in the literature pertains to FLVCR1-AS1. There appears to be either a typographical error or confusion regarding the gene symbol; thus, the canonical identity is established as FLVCR1-AS1 based on the supplied evidence[1][2].
