Role of Long Non-coding RNA HSD17B3-AS1 in Trauma for COVID-19.

COVID-19, an acute respiratory syndrome caused by the SARS-CoV-2 virus, was first reported in late 2019 in Wuhan, China, and rapidly escalated into a global pandemic. The condition can lead to organ dysfunction and ultimately death through its onset of acute respiratory distress syndrome (ARDS). Disease severity has been linked to proinflammatory cytokines which activate the NF-κB and STAT transcription factors in infected cells. It has been proven that lncRNAs play a very important role in reducing or increasing inflammatory factors. This makes them potentially valuable in recognizing pathogenesis pathways and therapeutic targets in COVID-19. Nanocurcumin is known as an antioxidant, tumor suppressor and anti-inflammatory substance, and it can be effective to reduce inflammation caused by the disease of COVID-19. This study analyzed Sequence Read Archive data from COVID-19 patients with acute versus milder symptoms, identifying dysregulated genes and non-coding RNAs. To verify this correlation, the expression of the candidate gene was evaluated with quantitative polymerase chain reaction (qPCR) in mouse models, while immunoglobulin (Ig) G titer was measured using enzyme-linked immunosorbent assay (ELISA) in mouse serum samples. Here we introduced a novel lncRNA called HSD17B3-AS1, suggested as a therapeutic target in COVID-19 patients with acute symptoms. Furthermore, we revealed nanocurcumin is reducing the expression of HSD17B3-AS1 which leads to reduced inflammation in mice. These results suggest that HSD17B3-AS1 plays a significant regulatory role in managing COVID-19, and the downregulation of HSD17B3-AS1 by Nanocurcumin presents a promising treatment option for minimizing complications in COVID-19 patients.
