TGF-β Targeted by miR-27a Modulates Anti-Parasite Responses of Immune System.

Background: Immune cells and their secreted cytokines are known as the first barrier against pathogens. as an intracellular protozoan produces anti-inflammatory cytokines that lead to proliferation and survival of the parasite in the macrophages. miRNAs are small non-coding RNA molecules that regulate mRNAs expression.

Mir-4699 promotes the osteogenic differentiation of mesenchymal stem cells.

Introduction: Mesenchymal stem cells (MSCs) are drawing considerable attention in the field of regenerative medicine due to their differentiation capabilities. The miRNAs are among the most important epigenetic regulators of MSC differentiation. Our previous study identified miR-4699 as a direct suppressor of the DKK1 and TNSF11 gene expression.

From the environment to the cells: An overview on pivotal factors which affect spreading and infection in COVID-19 pandemic.

Several factors ranging from environmental risks to the genetics of the virus and that of the hosts, affect the spread of COVID-19. The impact of physicochemical variables on virus vitality and spread should be taken into account in experimental and clinical studies. Another avenue to explore is the effect of diet and its interaction with the immune system on SARS-CoV-2 infection and mortality rate.

Discovering the signature of a lupus-related microRNA profile in the Gene Expression Omnibus repository.

Lupus is one of the most prevalent systemic autoimmune diseases. It is a multifactorial disease in which genetic, epigenetic and environmental factors play significant roles. The pathogenesis of lupus is not yet well understood.

Association of HDAC8 Expression with Pathological Findings in Triple Negative and Non-Triple Negative Breast Cancer: Implications for Diagnosis.

Background: Previous data have shown the tumorigenicity roles of histone deacetylase 8 (HDAC 8) in breast cancer. More recently, the oncogenic effects of this molecule have been revealed in triple negative breast cancer (TNBC). The present study aimed to determine the diagnostic value of HDAC8 for the differentiation of TNBC from nTNBC tumors.

MiR-216b-5p inhibits cell proliferation in human breast cancer by down-regulating HDAC8 expression.

Aim: Over-expression of histone deacetylase 8 (HDAC8) has been demonstrated in breast cancer. But the underlying molecular mechanism of HDAC8 on the progression of breast cancer remains unknown. MicroRNAs (miRs) are proposed as important molecules in cancer progression by targeting specific oncogenes or tumor-suppressor genes.

miR-483-3p suppresses the proliferation and progression of human triple negative breast cancer cells by targeting the HDAC8>oncogene.

Triple negative breast cancer (TNBC) is a heterogeneous subclass of breast cancer (BC) distinguished by lack of hormone receptor expression. It is highly aggressive and difficult to treat with traditional chemotherapeutic regimens. Targeted-therapy using microRNAs (miR) has recently been proposed to improve the treatment of TNBC in the early stages.

Wnt pathway targeting reduces triple-negative breast cancer aggressiveness through miRNA regulation in vitro and in vivo.

Triple-negative breast cancer, devoid of estrogen (ER), progesterone (PR), and human epidermal growth factor receptor 2 (HER-2) expression, is deprived of commonly used targeted therapies. MicroRNAs (miRNAs) are undergoing a revolution in terms of potentially diagnostic or therapeutic elements. Combining computational approaches, we enriched miRNA binding motifs of Wnt pathway-associated upregulated genes.

Is miR-144 an effective inhibitor of PTEN mRNA: a controversy in breast cancer.

Breast cancer is the first common cancer among women worldwide. One of the major signaling pathways playing a role in the onset and progression of this disease is PI3K/Akt/mTOR, which can be inhibited by PTEN. miRNAs are small non-coding molecules that regulate the expression of their targets by inhibition or suppression, and thus, their dysregulated expression results in the development of cancer.

The power of precise bioinformatics prediction of miRNA:mRNA interactions:miR-4699 as a potential inducer of Wnt signaling pathway.

microRNAs have attracted interest because of their regulatory effects on gene expression. Experimental detection of potential targets of miRNAs is a laborious task. Considering the expensive techniques of detection, computational approaches for miRNA target prediction can be used as the first step in miRNA research.

Biodegradable nano-polymers as delivery vehicles for therapeutic small non-coding ribonucleic acids.

Nowadays, small non-coding Ribo Nucleic Acids (sncRNAs) such as siRNA, miRNA and shRNA are extremely serving to gene regulation. They are involved in many biological processes and in an increasing number of studies regarding a variety of application of sncRNAs toward human health and relieving diseases ranging from metabolic disorders to those involving various organ systems as well as different types of cancer. One of the most severe limitations for applying RNA interference technology is the absence of safe and effective carriers for in vivo delivery, including localizing the molecules to a specific site of interest and sustaining the presentation of the payloads for a controlled period of time.
