Th17 Differentiation

Background and aims: miRNAs, as a class of non-coding RNAs, take part in different cellular processes. Dysregulation of different miRNAs has been reported in numerous disorders to date. Multiple sclerosis (MS) is an autoimmune disease with high prevalence in Iran and Th17 cells play an important role in its pathogenesis. In the current study, we aimed to predict the possible role of miR-34a and miR-215 in the process of controlling Th17 differentiation, and hence, their possible impact on the onset and progression of MS. Methods: We investigated probable interactions of miRNAs and genes that participate in Th17 cells differentiation using miRwalk database as an integrative one which utilizes 10 different algorithms to predict miRNA-mRNA interaction. Results: Based on our findings, miR-34a and miR-215 were predicted to have a potential role in the induction of Th17 cells differentiation. Conclusion: Conclusively, miR-34a and miR-215 may up-regulate Th17 cells of MS patients. Since bioinformatics data have shown that these miRNAs suppress negative regulatory genes in Th17 cells differentiation, we suppose that down-regulation of these miRNAs could ameliorate MS symptoms. Therefore, several therapeutic approaches may be considered for these miRNAs besides their application as valuable prognostic/diagnostic biomarkers in detection of various stages of MS.

Regulatory Functions

Diseases resulting from alterations in gene expressions through mutations in the genes or through changes in the gene expression regulation could be identified through the analysis of RNA expressions. ncRNAs play a significant role in regulation of the gene expression by controlling the expression levels of the coding RNAs and other cellular processes. Discoveries have shown that the human genome is encoded with sequences responsible for the transcription of thousands of ncRNAs. Even though the studies conducted on ncRNAs are still at initial stages, facts established so far display biomarkers that confirm their relationship with certain diseases such as cancers, cardiovascular diseases, and insulin resistance. These studies have been facilitated with high throughput modern sequencing techniques such as microarrays and RNA sequencing. The data obtained through the above analysis are processed with the aid of existing databases, to deduce conclusions on different diagnostic biomarkers and therapeutic targets for specific diseases. This review focuses on the association of ncRNAs in disease prediction, focusing mainly on cardiovascular diseases and disorders caused by insulin resistance. The report also analyzes regulatory functions of ncRNAs and novel approaches used in disease therapeutics.

: MicroRNAs (miRNAs) play a vital role in the onset and development of many diseases, including cancers. Emerging evidence shows that numerous miRNAs have the potential to be used as diagnostic biomarkers for cancers, and miRNA-based therapy may be a promising therapy for the treatment of malignant neoplasm. MicroRNA-145 (miR-145) has been considered to play certain roles in various cellular processes, such as proliferation, differentiation and apoptosis, via modulating expression of direct target genes. Recent reports show that miR-145 participates in the progression of digestive system cancers, and plays crucial and novel roles for cancer treatment. In this review, we summarize the recent knowledge concerning the function of miR-145 and its direct targets in digestive system cancers. We discuss the potential role of miR-145 as valuable biomarkers for digestive system cancers and how miR-145 regulates these digestive system cancers via different targets to explore the potential strategy of targeting miR-145.

Tumor Types

Alterations in the expression level of the MYC gene are often found in the cells of various malignant tumors. Overexpressed MYC has been shown to stimulate the main processes of oncogenesis: uncontrolled growth, unlimited cell divisions, avoidance of apoptosis and immune response, changes in cellular metabolism, genomic instability, metastasis, and angiogenesis. Thus, controlling the expression of MYC is considered as an approach for targeted cancer treatment. Since c-Myc is also a crucial regulator of many cellular processes in healthy cells, it is necessary to find ways for selective regulation of MYC expression in tumor cells. Many recent studies have demonstrated that non-coding RNAs play an important role in the regulation of the transcription and translation of this gene and some RNAs directly interact with the c-Myc protein, affecting its stability. In this review, we summarize current data on the regulation of MYC by various non-coding RNAs that can potentially be targeted in specific tumor types.

Multiple Sclerosis Patients

Multiple sclerosis (MS) is a common disabling neurologic disease with an overall prevalence in Canada of 240 in 100,000. Multiple sclerosis clinics are located at tertiary-care centers that may be difficult for a patient to access during an acute relapse. Many relapses are evaluated by primary-care physicians in private clinics or emergency departments, but these physicians' familiarity with MS is not known. Therefore, a survey was undertaken to determine the knowledge and experience of primary-care physicians regarding the diagnosis and treatment of MS relapses. A total of 1282 licensed primary-care physicians in the catchment area of the London (Ontario, Canada) Multiple Sclerosis Clinic were identified and mailed a two-page anonymous survey. A total of 237 (18.5%) responses were obtained, but only 216 (16.8%) of these respondents were still in active practice. Of these 216 physicians, only 9% reported having no MS patients in their practice, while 70% had one to five patients, 16.7% had six to ten, and 1.9% had more than ten (3.7% did not respond to this question). Corticosteroids were recognized as an MS treatment by 49.5% of the respondents, but only 43.1% identified them as a treatment for acute relapses. In addition, 31% did not know how to diagnose a relapse, and only 37% identified new signs or symptoms of neurologic dysfunction as indicating a potential relapse. Despite the high prevalence of MS in Canada, primary-care physicians require more education and support from specialists in MS care regarding the diagnosis and treatment of MS relapses.

Th17 Differentiation

Uncontrolled activity of T cells mediates autoimmune and inflammatory diseases such as multiple sclerosis, inflammatory bowel diseases, rheumatoid arthritis, type 1 diabetes, and atherosclerosis. Recent findings suggest that enhanced activity of interleukin-17 (IL-17) producing T helper 17 cells (Th17 cells) plays an important role in autoimmune diseases and inflammatory diseases. Previous papers have revealed that a lipid-lowering synthetic ligand of peroxisome proliferator-activated receptorα(PPARα), fenofibrate, alleviates both atherosclerosis and a few nonlipid-associated autoimmune diseases such as autoimmune colitis and multiple sclerosis. However, the link between fenofibrate and Th17 cells is lacking. In the present study, we hypothesized that fenofibrate inhibited the differentiation of Th17 cells. Our results showed that fenofibrate inhibited transforming growth factor-β(TGF-β) and IL-6-induced differentiation of Th17 cellsin vitro. However, other PPARαligands such as WY14643, GW7647 and bezafibrate did not show any effect on Th17 differentiation, indicating that this effect of fenofibrate might be PPARαindependent. Furthermore, our data showed that fenofibrate reduced IL-21 production and STAT3 activation, a critical signal in the Th17 differentiation. Thus, by ameliorating the differentiation of Th17 cells, fenofibrate might be beneficial for autoimmunity and inflammatory diseases.

Multiple Sclerosis (MS) is a devastating demyelinating disease with a very high prevalence in North-East Scotland and in the Orkney and Shetland Islands. MS appears to be a multifactorial disorder with environmental and genetic elements and it has been proposed that these, in tandem, provoke an autoimmune response giving rise to the disease. Although there is no direct evidence of a specific virus being involved in MS, there are nevertheless grounds for suspecting a viral association. This review discusses these aspects of MS and suggests that a more aggressive approach to unravelling the role of viruses is needed.

Alzheimer’s disease (AD) is the most common cause of senile dementia. Although AD research has made important breakthroughs, the pathogenesis of this disease remains unclear, and specific AD diagnostic biomarkers and therapeutic strategies are still lacking. Recent studies have demonstrated that neuroinflammation is involved in AD pathogenesis and is closely related to other health effects. MicroRNAs (miRNAs) are a class of endogenous short sequence non-coding RNAs that indirectly inhibit translation or directly degrade messenger RNA (mRNA) by specifically binding to its 3′ untranslated region (UTR). Several broadly expressed miRNAs including miR-21, miR-146a, and miR-155, have now been shown to regulate microglia/astrocytes activation. Other miRNAs, including miR-126 and miR-132, show a progressive link to the neuroinflammatory signaling. Therefore, further studies on these inflamma-miRNAs may shed light on the pathological mechanisms of AD. The differential expression of inflamma-miRNAs (such as miR-29a, miR-125b, and miR-126-5p) in the peripheral circulation may respond to AD progression, similar to inflammation, and therefore may become potential diagnostic biomarkers for AD. Moreover, inflamma-miRNAs could also be promising therapeutic targets for AD treatment. This review provides insights into the role of inflamma-miRNAs in AD, as well as an overview of general inflamma-miRNA biology, their implications in pathophysiology, and their potential roles as biomarkers and therapeutic targets.

Ms Pathogenesis

Multiple sclerosis (MS) is an early onset chronic neurological condition in adults characterized by inflammation, demyelination, gliosis, and axonal loss in the central nervous system. The pathological cause of MS is complex and includes both genetic and environmental factors. Non-protein-coding RNAs (ncRNAs), specifically miRNAs and lncRNAs, are important regulators of various biological processes. Over the past decade, many studies have investigated both miRNAs and lncRNAs in patients with MS. Since then, insightful knowledge has been gained in this field. Here, we review the role of miRNAs and lncRNAs in MS pathogenesis and discuss their implications for diagnosis and treatment.
