Small interfering RNA (siRNA), sometimes known as short interfering RNA or silencing RNA, is a class of double-stranded RNA molecules, 20-25 nucleotides in length, that play a variety of roles in biology. Most notably, siRNA is involved in the RNA interference (RNAi) pathway, where it interferes with the expression of a specific gene. In addition to their role in the RNAi pathway, siRNAs also act in RNAi-related pathways, e.g., as an antiviral mechanism or in shaping the chromatin structure of a genome; the complexity of these pathways is only now being elucidated.
Any drug that is taken orally must pass through the lining of the digestive tract. Transporter proteins found on cells that line the GI tract help with this process, but for many drugs, it's unknown which of those transporters they use to exit the digestive tract.
Society learned about the value of mRNA during the COVID-19 pandemic when we saw scientists and medical professionals harness its power to deliver a vaccine for the virus within a year.
Researchers confirm that the established pre-mRNA splicing mechanism that appears in textbooks cannot work in a subset of human short introns: A novel SAP30BP–RBM17 complex-dependent splicing has been uncovered.
Some Covid-19 vaccines safely and effectively used lipid nanoparticles (LNPs) to deliver messenger RNA to cells. A new MIT study shows that different nanoparticles could be used for a potential Alzheimer's disease (AD) therapy.
Researchers at UC Davis Comprehensive Cancer Center have shown that inhibiting a specific protein using gene therapy can shrink hepatocellular carcinoma (HCC) in mice.
Pleural mesothelioma (PM) is mainly caused by asbestos exposure and characterized by poor prognosis and limited therapeutic options.
Researchers from the Johns Hopkins Malaria Research Institute at the Johns Hopkins Bloomberg School of Public Health have made an important finding about Aedes aegypti mosquitoes-;one that could one day lead to better methods for reducing the mosquito-to-human transmission of dengue, yellow fever, Zika, and other harmful and sometimes deadly viruses.
With obesity rates projected to continue rising globally, there is an urgent need to understand the intricate mechanisms that contribute to metabolic diseases such as diabetes.
For the 314,000 people diagnosed with ovarian cancer each year, hope often comes in the form of platinum-based drugs such as cisplatin.
Amgen today announced data from the final analysis of the Phase 2 OCEAN(a)-DOSE study of olpasiran, a small interfering RNA (siRNA) during the Late-Breaking Science Session at the European Society of Cardiology (ESC) Annual Meeting being held in Amsterdam. In the off-treatment extension period, olpasiran showed a lasting effect on Lp(a) reduction nearly a year after the last dose.
Primary liver cancers ranked as the sixth most commonly diagnosed cancers and the third leading cause of cancer-related death in 2020. Among all primary liver cancers, HCC is the most common cancer, accounting for more than 80% of cases with a 5-year survival rate of less than 10% in Western countries.
Researchers reported on lentiviral pseudovirions pseudotyped with SARS-CoV-2.
A new research paper was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 13, entitled, "Budding uninhibited by benzimidazoles-1 (BUB1) regulates EGFR signaling by reducing EGFR internalization."
Review discusses the increasing importance of two-dimensional nanomaterials like graphene in neuroscience, highlighting their potential in nerve repair, creating brain-mimicking synaptic devices, and treating neurological disorders. It also considers the challenges and future prospects of these materials in this complex field.
Scientists at UMass Chan Medical School have developed a technology to deliver gene therapy directly to lung tissue through intranasal administration, a development that could potentially create a new class of treatments for lung disease.
Small interfering RNAs (siRNAs) are novel therapeutics that can be used to treat a wide range of diseases.
This paper discusses the use of RNA lipid nanoparticles for cancer immunotherapy, which has shown promising results in clinical use. However, only a small percentage of patients respond to existing immunotherapies, and the paper explores opportunities for improvement.
Monthly prophylactic injections of fitusiran are effective in reducing bleeds in patients with hemophilia A or B, according to randomized controlled trials publishing simultaneously in The Lancet and The Lancet Haematology journals.
Researchers summarized studies on the association between high-density lipoprotein cholesterol and different types of cancer
