Dental complications as a potential indicator of Redondovirus infection: a cross-sectional study.

Background: Redondoviridae is a newly discovered virus family linked to oral and respiratory conditions in people, while there is still debate about whether it is also coinfected with other respiratory viruses. This study aimed to determine the frequency of Redondovirus (ReDoV) in nasopharyngeal samples and to investigate any possible links to SARS-CoV-2 infections.

Methods: A polymerase chain reaction (PCR) test was conducted on 731 nasopharyngeal samples from individuals referred to medical centers in Tehran, Iran, for SARS-CoV-2 testing to investigate the prevalence of ReDoV.

Expression pattern analysis of the long non-coding RNAs (TINCR, RP11-573D15.8, RP11-156E8.1), and their target genes (AKT1, FOXO1 and MAPK3) in patients with HIV infection, and elite controllers.

Elite controllers (ECs) defined as a small subclass of subjects with HIV capable of controlling human immunodeficiency virus (HIV) replication in the lack of antiretroviral treatment. One class of RNA molecules that serve as vital components in the network of HIV-related transcriptional regulation, are long noncoding RNAs (lncRNAs). The critical part that they take is in transcriptional regulation of HIV through monitoring various cellular signaling pathways.

The interplay between mitochondrial dysfunction and NLRP3 inflammasome in multiple sclerosis: Therapeutic implications and animal model studies.

Multiple sclerosis (MS) is a complex autoimmune disorder that impacts the central nervous system (CNS), resulting in inflammation, demyelination, and neurodegeneration. The NOD-like receptor (NLR) family pyrin domain-containing 3 (NLRP3) inflammasome, a multiprotein complex of the innate immune system, serves an essential role in the pathogenesis of MS by regulating the production of pro-inflammatory cytokines (IL-1β & IL-18) and the induction of pyroptotic cell death. Mitochondrial dysfunction is one of the main potential factors that can trigger NLRP3 inflammasome activation and lead to inflammation and axonal damage in MS.

Exploring the immune-modulating properties of boswellic acid in experimental autoimmune encephalomyelitis.

Multiple sclerosis (MS) is a condition where the central nervous system loses its myelin coating due to autoimmune inflammation. The experimental autoimmune encephalomyelitis (EAE) simulates some aspects of human MS. Boswellic acids are natural compounds derived from frankincense extract, known for their anti-inflammatory properties.

Divergent functions of NLRP3 inflammasomes in cancer: a review.

The cancer is a serious health problem, which is The cancer death rate (cancer mortality) is 158.3 per 100,000 men and women per year (based on 2013-2017 deaths). Both clinical and translational studies have demonstrated that chronic inflammation is associated with Cancer progression.

Down-regulation of and miR-132 in ductal carcinoma of the breast.

Introduction: miR-132-3p acts in normal breast development and its downregulation has been documented in breast cancer. One of the targets of miR-132-3p is which is also inactivated in breast cancer. The interactions between and miR-132 have been reported in several pathological conditions.

High resolution melting curve analysis for rapid detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants.

Since the emergence of the original Wuhan SARS-CoV-2 strain, several new variants of the virus have emerged. Alpha, Beta, Gamma, Delta and the most recent Omicron variants have been introduced during this pandemic. Several methods including, but not restricted to, allele-specific PCR, ligation with rolling circle amplification and real-time PCR with allele-specific probes are able to detect mutations as low as a single nucleotide polymorphism.

The expression patterns of MALAT-1, NEAT-1, THRIL, and miR-155-5p in the acute to the post-acute phase of COVID-19 disease.

Introduction: One of the hallmarks of COVID-19 is overwhelming inflammation, which plays a very important role in the pathogenesis of COVID-19. Thus, identification of inflammatory factors that interact with the SARS-CoV-2 can be very important to control and diagnose the severity of COVID-19. The aim of this study was to investigate the expression patterns of inflammation-related non-coding RNAs (ncRNAs) including MALAT-1, NEAT-1, THRIL, and miR-155-5p from the acute phase to the recovery phase of COVID-19.

MicroRNA let-7 and viral infections: focus on mechanisms of action.

MicroRNAs (miRNAs) are fundamental post-transcriptional modulators of several critical cellular processes, a number of which are involved in host defense mechanisms. In particular, miRNA let-7 functions as an essential regulator of the function and differentiation of both innate and adaptive immune cells. Let-7 is involved in several human diseases, including cancer and viral infections.

An Update on the Effects of Probiotics on Gastrointestinal Cancers.

Because of their increasing prevalence, gastrointestinal (GI) cancers are regarded as an important global health challenge. Microorganisms residing in the human GI tract, termed gut microbiota, encompass a large number of living organisms. The role of the gut in the regulation of the gut-mediated immune responses, metabolism, absorption of micro- and macro-nutrients and essential vitamins, and short-chain fatty acid production, and resistance to pathogens has been extensively investigated.

Therapeutic effect of curcumin in gastrointestinal cancers: A comprehensive review.

Gastrointestinal (GI) cancers with a high global prevalence are a leading cause of morbidity and mortality. Accordingly, there is a great need to develop efficient therapeutic approaches. Curcumin, a naturally occurring agent, is a promising compound with documented safety and anticancer activities.

Oncogenic viruses and chemoresistance: What do we know?

Chemoresistance is often referred to as a major leading reason for cancer therapy failure, causing cancer relapse and further metastasis. As a result, an urgent need has been raised to reach a full comprehension of chemoresistance-associated molecular pathways, thereby designing new therapy methods. Many of metastatic tumor masses are found to be related with a viral cause.

Chitosan-Based Nanoparticles Against Viral Infections.

Viral infections, in addition to damaging host cells, can compromise the host immune system, leading to frequent relapse or long-term persistence. Viruses have the capacity to destroy the host cell while liberating their own RNA or DNA in order to replicate within additional host cells. The viral life cycle makes it challenging to develop anti-viral drugs.

Pivotal Role of TGF-β/Smad Signaling in Cardiac Fibrosis: Non-coding RNAs as Effectual Players.

Unintended cardiac fibroblast proliferation in many pathophysiological heart conditions, known as cardiac fibrosis, results in pooling of extracellular matrix (ECM) proteins in the heart muscle. Transforming growth factor β (TGF-β) as a pivotal cytokine/growth factor stimulates fibroblasts and hastens ECM production in injured tissues. The TGF-β receptor is a heterodimeric receptor complex on the plasma membrane, made up from TGF-β type I, as well as type II receptors, giving rise to Smad2 and Smad3 transcription factors phosphorylation upon canonical signaling.

Autophagy-related microRNAs: Possible regulatory roles and therapeutic potential in and gastrointestinal cancers.

Gastrointestinal (GI) cancers with a high incidence rate and adverse complications are associated with severe morbidity and mortality around the world. It is well recognized that early detection of the disease results in longer survival rate and better quality of life. Autophagy, an intracellular regulatory process, has been shown to play an essential role in the pathogenesis of various malignancies including GI cancers.
