Objective. Hashimoto’s thyroiditis, also known as chronic lymphocytic thyroiditis, is a common autoimmune thyroiditis, which mostly occurs in young and middle-aged women. It can be manifested as hyperthyroidism in the early stage; hypothyroidism may appear with the progression of the disease. Studies have shown that multiple factors such as heredity, environment, and autoimmunity are involved in the pathogenesis, but the specific mechanism is not clear. In our study, we tried to find key genes and potential molecular mechanisms of Hashimoto’s thyroiditis to provide new ideas for the therapeutic targets of Hashimoto’s thyroiditis. Method. GSE138198 and GSE54958 were downloaded from the GEO database, and two datasets were combined for analysis. The combined data were normalized to identify the differentially expressed genes (DEGs), and GO and KEGG enrichment analyses were performed. Protein-protein interaction (PPI) networks and hub genes between DEGs were identified. We also used the miRWalk database to identify regulatory miRNAs associated with expressions of DEGs. Result. We identified 182 DEGs (160 upregulated and 22 downregulated) between Hashimoto’s disease patients and the healthy control group. GO analysis showed that DEGs were mostly concentrated in detection of chemical stimulus involved in sensory perception, intermediate filament cytoskeleton, and olfactory receptor activity. KEGG pathway analysis showed that DEGs were mainly related to olfactory transduction. Some members of the KRTAP family and HTR5A, KNG1, DRD3, HTR1D, TAS2R16, INSL5, TAS2R42, and GRM7 are the most important hub genes in the PPI network. In addition, we recognized that OTUD4, LLPH, and ECHDC1 were the most important hub genes in the miRNA-target gene network. Conclusion. In this study, a series of bioinformatics analyses of DEGs were performed to identify the key genes and pathways associated with Hashimoto’s thyroiditis. These genes and pathways provide a more detailed understanding of the pathogenesis of Hashimoto’s disease and provide new ideas for the therapeutic targets of Hashimoto’s thyroiditis.

Background: Hashimoto’s disease is a chronic, autoimmune form of thyroiditis and is one of the most common causes for hypothyroidism. Many studies have found an association between Hashimoto’s thyroiditis and various other thyroid pathologies, including cancers. The objectives of the study were to look for any association between Hashimoto’s thyroiditis and other forms of thyroid diseases and to analyse the pattern of patients treated with Hashimoto’s thyroiditis.Methods: This was a retrospective study conducted at a tertiary care centre from December 2008 to January 2014. Patients with Hashimoto’s thyroiditis confirmed by histology were selected as the cases. Their clinical and biochemical data and post-operative histopathological reports were collected and analysed.Results: 300 patients who underwent thyroidectomy were found to have a diagnosis of Hashimoto’s thyroiditis. 97.33% of the patients were females. Maximum patients belonged to the 31-40 age group. Of the 300 patients, 61.67% had other associated pathologies. The maximum association was with colloid goiters, followed by adenomas and malignancies. Among the malignancies, 80.65% were papillary cancers while the rest were follicular cancers. There were no cases of other malignancies associated with Hashimoto’s thyroiditis.Conclusions: Hashimoto’s thyroiditis is fairly common in the studied population, mostly among females. It is associated with other thyroid pathologies including differentiated cancers. Lymphoma is not found to be associated with Hashimoto’s disease in our population. Hashimoto’s thyroiditis thus forms a major share of goiters leading to thyroidectomy in Indian population. However, the decision to operate should be primarily governed by the associated cytology.

P53 Signaling Pathway

Diabetic neuropathy (DN) is one of the chronic complications of diabetes which can cause severe harm to patients. In order to determine the key genes and pathways related to the pathogenesis of DN, we downloaded the microarray data set GSE27382 from Gene Expression Omnibus (GEO) and adopted bioinformatics methods for comprehensive analysis, including functional enrichment, construction of PPI networks, central genes screening, TFs-target interaction analysis, and evaluation of immune infiltration characteristics. Finally, we examined quantitative real- time PCR (qPCR) to validate the expression of hub genes. A total of 318 differentially expressed genes (DEGs) were identified, among which 125 upregulated DEGs were enriched in the mitotic nuclear division, extracellular region, immunoglobulin receptor binding, and p53 signaling pathway, while 193 downregulated DEGs were enriched in ion transport, membrane, synapse, sodium channel activity, and retrograde endocannabinoid signaling. GSEA plots showed that condensed nuclear chromosome kinetochore were the most significant enriched gene set positively correlated with the DN group. Importantly, we identified five central genes (Birc5, Bub1, Cdk1, Ccnb2, and Ccnb1), and KEGG pathway analysis showed that the five hub genes were focused on progesterone-mediated oocyte maturation, cell cycle, and p53 signaling pathway. The proportion of immune cells from DN tissue and normal group showed significant individual differences. In DN samples, T cells CD4 memory resting and dendritic cells resting accounted for a higher proportion, and macrophage M2 accounted for a lower proportion. In addition, all five central genes showed consistent correlation with immune cell infiltration levels. qPCR showed the same expression trend of five central genes as in our analysis. Our research identified key genes related to differential genes and immune infiltration related to the pathogenesis of DN and provided new diagnostic and potential therapeutic targets for DN.

Chronic Autoimmune Thyroiditis

Hashimoto’s thyroiditis (HT), also known as chronic lymphocytic thyroiditis is one of the most frequent types of inflammation of the thyroid gland. The prevalence of the overt HT is about 2% but it is believed that Hashimoto thyroiditis is more frequent than expected. Hashimoto’s thyroiditis is characterized by dysfunction of the immune system, which leads to impaired tolerance of own tissues and increased production of autoantibodies against the thyroid cells. Thyroid peroxidase antibodies (anti-TPO), thyroglobulin antibodies (anti-Tg) and/or TSH receptors antibodies are the principal markers of the disease. The essential element of the treatment of HT is the supplementation of L-thyroxine. In Hashimoto’s disease, like in many other autoimmune diseases, researchers attempted to support pharmacological treatment by adequate nutrition. The aim of this paper was to review the existing literature on the levels of antioxidants (vitamin A, C, E, selenium, zinc) and vitamin D in patients with HT, as well as the influence of the nutritional supplementation of the above mentioned elements on the metabolism of the thyroid gland hormones and the level of anti-thyroid peroxidase (anti-TPO) antibodies.

Oral squamous cell carcinoma (OSCC) is one of the most common types of cancer worldwide. Due to the lack of early detection and treatment, the survival rate of OSCC remains poor and the incidence of OSCC has not decreased during the past decades. To explore potential biomarkers and therapeutic targets for OSCC, we analyzed differentially expressed genes (DEGs) associated with OSCC using RNA sequencing technology. Methylation−regulated and differentially expressed genes (MeDEGs) of OSCC were further identified via an integrative approach by examining publicly available methylomic datasets together with our transcriptomic data. Protein−protein interaction (PPI) networks of MeDEGs were constructed and highly connected hub MeDEGs were identified from these PPI networks. Subsequently, expression and survival analyses of hub genes were performed using The Cancer Genome Atlas (TCGA) database and the Gene Expression Profiling Interactive Analysis (GEPIA) online tool. A total of 56 upregulated MeDEGs and 170 downregulated MeDEGs were identified in OSCC. Eleven hub genes with high degree of connectivity were picked out from the PPI networks constructed by those MeDEGs. Among them, the expression level of four hub genes (CTLA4, CDSN, ACTN2, and MYH11) were found to be significantly changed in the head and neck squamous carcinoma (HNSC) patients. Three hypomethylated hub genes (CTLA4, GPR29, and TNFSF11) and one hypermethylated hub gene (ISL1) were found to be significantly associated with overall survival (OS) of HNSC patients. Therefore, these hub genes may serve as potential DNA methylation biomarkers and therapeutic targets of OSCC.

Background Cancer metastasis is well known as the most adverse outcome and the major cause of mortality in cancer patients, including prostate cancer (PCa). There are no credible predictors, to this day, that can reflect the metastatic ability of localized PCa. In the present study, we firstly identified the differentially expressed genes (DEGs) and molecular pathways involved in the metastaic process of PCa by comparing gene expressions of metastaic PCa with localized PCa directly, with the purpose of identifying potential markers or therapeutic targets. Methods The gene expression profiles (GSE6919 and GSE32269) were downloaded from the Gene Expression Omnibus database, which contained 141 tissue samples, including 87 primary localized PCa samples and 54 metastaic PCa samples. After data processing, DEGs were identified by R language using the Student’s t-test adjusted via the Beniamini–Hochberg method. Subsequently, the gene ontology functional and pathway enrichment analyses of DEGs were performed and the protein–protein interaction network was constructed. Hub genes were identified using the plug-in cytoHubba in Cytoscape software by MCC and degree. Furthermore, validation and prognostic significance analysis of the hub genes were performed by UALCAN and gene expression profiling interactive analysis (GEPIA). Results A total of 90 DEGs were identified between localized and metastaic PCa, which consisted of 47 upregulated and 43 downregulated genes. The enriched functions and pathways of the DEGs include catabolic process, cell cycle, response to steroid hormone, extracellular matrix (ECM)-receptor interaction and vascular smooth muscle contraction. A total of 10 genes were identified as hub genes and biological process analysis of hub genes showed that cell cycle phase, cell division, and mitotic cell cycle process were mainly enriched. The expression of hub genes were confirmed in metastaic PCa when compared with localized PCa tissues by The Cancer Genome Atlas database. Moreover, the disease-free survival analysis of hub genes revealed that these genes may play an important role in invasion, progression or recurrence. Therefore, these hub genes might be the key genes contributed to tumor progression or metastasis in PCa and provide candidate therapeutic targets for PCa. Conclusions The present study identified some DEGs between localized and metastaic PCa tissue samples. These key genes might be potential therapeutic targets and biomarkers for the metastaic process of PCa.
