The Role of lncRNA AF117829.1 in the Immunological Pathogenesis of Severe Aplastic Anaemia

Abstract: Objective. Severe aplastic anaemia (SAA) is an autoimmune disease with immune tolerance dysfunction mediated by hyperactivated T lymphocytes that target the haematopoietic system. Numerous studies suggest that long noncoding RNAs (lncRNAs) play a significant role in almost every level of gene function/regulation. However, their specific mechanisms in SAA remain undetermined. This study is aimed at determining the role of key lncRNAs in CD8+ T lymphocytes in the mechanisms of SAA. Methods. RNA-seq was performed… Show more

“…In bone metastatic melanoma, AL118506.1 (antisense to abhydrolase domain containing 16B) participates in the ceRNA network of has-miR-27b-3p/AL118506.1/THBS2, which has great utility in predicting survival and metastasis of melanoma ( Huang et al, 2019 ). In severe aplastic anemia (SAA) patients, the decreased expression of AF117829.1 upregulates the activity of CD8 + T lymphocytes, which means lncRNA may be associated with the regulation of the immune microenvironment ( Li et al, 2021 ). POC1B-AS1 is also a risk factor in the prognostic model of endometrial carcinoma ( Liu J. et al, 2021 ).…”

“…The lncRNA AF11782.1 mechanism of action remains unknown but was related to the proliferation, differentiation, and regulation of the immunity of T cells [68,69], and as presented earlier, his expression was found to be related to metastatic development and worst prognosis of ccRCC patients, indicating new actions within the cancer field of studies. At this cluster, due to the high level of expression, a sponge act could be existing where the miRNA doesn't degrade the POLE2 and HMMR, promoting cell differentiation and metastasis development.…”

“…The Hyaluronan Mediated Motility Receptor (HMMR) is responsible for the regulation of tumor cell motility [51], and its knockdown reduced peritoneal metastasis in gastric cancer [52]. The role of lncRNA AF117829.1 remains unknown, but it was described as related to the proliferation, differentiation, and regulation of T-cell immunity [53,54], and its expression is implied with metastatic development and the worst prognosis of ccRCC patients. In this context, the lncRNA AF117829.1 could be acting as a sponge over the miRNA, impairing the degradation of POLE2 and HMMR, and promoting cell differentiation and metastasis development.…”
