The hippo signaling pathway is a tumor-suppressive pathway, that regulates organ size, and cell regeneration. Dysregulation of the hippo pathway by the epigenetic modulator, noncoding RNAs (ncRNA) including microRNA(miR) promotes tumorigenesis through many cellular processes, including over proliferation, apoptosis resistance, and cell migration. This study aimed to identify aberrantly expressed miR, associated pathways, and targeted genes in BC. Data of mostly studied miRs were obtained from the miR Cancer database and PubMed. In addition pathway analysis and target prediction of scrutinized miRs were performed by DIANA miRPath v.3.Further functional and enrichment analyses of selected miRs were performed by Gene ontology(GO) annotation tool in DIANA miRPath v.3.Total nine hundred fifteen studies were included for analysis from which 54 mostly studied miRs were identified. Pathway enrichment analysis showed that among 54 miRs, 40 miRs have been significantly associated with core components of the hippo pathway (p-0.00049).i.e. Salvador Family WW Domain-Containing Protein (SAV1), Mammalian STE20-like 1/2(MST1/2), Mps One Binder Kinase Activator Protein 1(MOB1A/B), Large Tumor Suppressor Kinase 1/2 (LATS1/2), Yes-Associated Protein (YAP1), Transcriptional Coactivator With PDZ-binding Motif (TAZ), TEA Domain Transcription Factor (TEAD). The top nine miRs that were strongly associated with these genes have been selected from 40 miRs.

These miRs play a very important role in apoptosis, tumor development and metastasis, and the prognosis of BC. Hence, the interaction of these miRs with the hippo pathway would modulate the molecular mechanism of the hippo signaling pathway.

In RA, the immune system erroneously attacks the tissue surrounding the joints, resulting in stiffness, inflammation, pain, and mobility restrictions, particularly in areas such as the wrists, spine, knees, ankles, and feet. While numerous genes in the human genome play a part in the development of RA, specific genetic regions within these genes may have a noteworthy influence on both the initiation and progression of RA and this influence may extend to other inflammatory conditions as well.&lt;/p&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Method&lt;/h3&gt;&lt;p&gt;In a case-control study, genomic DNA (gDNA) was isolated from the peripheral blood of 200 individuals. These participants were categorized into two groups: one comprising 100 individuals diagnosed with rheumatoid arthritis, and the other composed of 100 healthy individuals who served as the control group. Various laboratory parameters and anthropometric data, such as age, gender, body mass index (BMI), levels of anti-cyclic citrullinated peptide (anti-CCP), and rheumatoid factor (RF), were assessed. Subsequently, all samples were genotyped for two specific polymorphisms located within the NOD2 gene (rs3135499 and rs3135500) using rhAmp-polymerase chain reaction technology. Finally, the collected data underwent analysis using a range of statistical methods.&lt;/p&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;p&gt;The results indicated a substantial correlation between the risk of developing rheumatoid arthritis (RA) and the allele frequencies of the rs3135500G &gt; A polymorphism, specifically [G vs A; Odds Ratio (OR) = 1.76; 95% Confidence Interval (CI) (1.8 – –2.6); &lt;em&gt;p&lt;/em&gt; &lt; 0.005], as well as the genotypes [GG vs GA + AA; OR = 2.4; 95% CI (1.15–2.2), &lt;em&gt;p&lt;/em&gt; &lt; 0.001], [GA vs GG; OR = 0.1; 95% CI (0.33–0.4), p &lt; 0.001], and [AA vs GG; OR = 0.08; 95% CI (0.02–0.37), p &lt; 0.001]. Conversely, the rs3135499 A &gt; C polymorphism did not exhibit significant variations, except for [CC vs AA+AC; OR = 2.7; 95% CI (1.3–5.73), &lt;em&gt;p&lt;/em&gt; &lt; 0.009], and [AC vs AA; OR = 2.95; 95% CI (0.87–10.02), &lt;em&gt;p&lt;/em&gt; &lt; 0.03] after adjusting for factors like gender, age, BMI, smoking status, and family history. It's worth noting that markers such as anti-CCP, RF, and CRP produced positive results exclusively among RA patients. Additionally, parameters like BMI, ESR, WBCs, and Urea exhibited significant differences between the RA group and the healthy control group (&lt;em&gt;p&lt;/em&gt; &lt; 0.02, &lt;em&gt;p&lt;/em&gt; &lt; 0.0001, &lt;em&gt;p&lt;/em&gt; &lt; 0.002, and &lt;em&gt;p&lt;/em&gt; &lt; 0.01, respectively).
