HIV-1 infection is the cause of acquired immune deficiency syndrome (AIDS). Highly active antiretroviral therapy (HAART) has been successful in reducing the rate of progression to AIDS, but a cure has not yet been achieved. New tools are required to delay progression of infection or to block the replication cycle of HIV. RNA interference (RNAi) has the potential to work as a powerful tool against HIV infection. The mode of action of small interfering RNAs (siRNAs) against their target genes is through sequence complementarity, which in turn results in target degradation. siRNAs are showing enormous potential to be used as a therapeutic tool in various diseases; however, this technology still requires refinement before its full potential can be utilized for the development of HIV therapies.

Full-length hepatitis B virus (HBV) transcripts of chimpanzees and patients treated with multidose (MD) HBV siRNA ARC-520 and entecavir (ETV) were characterized by single-molecule real-time (SMRT) sequencing, identifying multiple types of transcripts with the potential to encode HBx, HBsAg, HBeAg, core, and polymerase, as well as transcripts likely to be derived from dimers of dslDNA, and these differed between HBeAg-positive (HBeAg+) and HBeAg-negative (HBeAg-) individuals. HBV transcripts from the last follow-up ~30 months post-ARC-520 treatment were categorized from one HBeAg+ (one of two previously highly viremic patients that became HBeAg- upon treatment and had greatly reduced cccDNA products) and four HBeAg- patients. The previously HBeAg+ patient received a biopsy that revealed that he had 3.

, a major vector of dengue virus (DENV), has a global distribution. Identifying the key components of the ubiquitin system of essential for the replication of viruses could help identify targets for developing broad-spectrum antiviral strategies. This study explores the interaction between E2 ubiquitin-conjugating enzymes (Ubc9) and DENV-2 proteins (NS1, NS5, and E) using cell culture and mosquito models.

The hallmark of Alzheimer's disease (AD) is the buildup of amyloid-β (Aβ), which is produced when the amyloid precursor protein (APP) misfolds and deposits as neurotoxic plaques in the brain. A functional iron responsive element (IRE) RNA stem loop is encoded by the APP 5'-UTR and may be a target for regulating the production of Alzheimer's amyloid precursor protein. Since modifying Aβ protein expression can give anti-amyloid efficacy and protective brain iron balance, targeted regulation of amyloid protein synthesis through modulation of 5'-UTR sequence function is a novel method for the prospective therapy of Alzheimer's disease.

In the search for effective strategies to control the Colorado Potato Beetle, RNA interference technology has emerged as a promising method due to its capacity to suppress genes selectively. Factors such as the target gene and double-stranded RNA (dsRNA) length are critical for optimizing gene silencing efficiency. In this study, we designed and synthesized in vitro dsRNAs of varying lengths targeting the gene, which encodes the AChE1 isoform of acetylcholinesterase in the beetle.

Wireworms are the most destructive soil insect pests affecting horticultural crops. The damage often renders them unsuitable for commercial purposes, resulting in substantial economic losses. RNA interference (RNAi) has been broadly used to inhibit gene functions to control insect populations.
