Clinicopathological characteristics of SMAD4 gene expressions in colorectal cancer patients.

Colorectal cancer (CRC) ranks as the third leading cause of cancer-related deaths globally. SMAD4 gene acts as the central mediator of the signaling pathway for transforming growth factor-β (TGFβ) with a significant effect on colorectal cancer. Previous research has confirmed a relationship between the presence of the SMAD4 gene and the survival and progression of colorectal cancer in patients.

Association of the OPRM1 variant and clinical manifestations in tramadol poisoned patients: a cross-sectional study.

Introduction: The opioid receptor mu1 is a protein coding gene that can have different codes for a protein and may have variations (polymorphisms) affecting how opioids work. The aim of this study was to investigate the prevalence of the most common opioid receptor mu1 polymorphism () and any relationship between this polymorphism and features following tramadol overdose.

Materials And Methods: This was a cross-sectional study of patients admitted with tramadol poisoning to an Iranian hospital.

Correlation of IDH1 gene expression error in breast tumor biopsy in patients with invasive ductal carcinoma.

One of the most important cancers in terms of worldwide prevalence is breast tumors, which have been less investigated in correlation with the enzyme Isocitrate Dehydrogenase 1 (IDH1) gene. The aim of this study was that expression of this gene could have significant effects on the progression of metastasis and invasive disease in breast cancer patients. We used the molecular method of RT-PCR with SYBR-Green to analyze breast tumor tissue from patients with metastasis and non-metastasis, the latter confirmed by the pathology department of Shohada-e Tajrish Hospital (serving as a control group).

Molecular Characteristics of TYK2 Gene Expressions in Patients with Colorectal Cancer.

Background: TYK2 is a member of the JAK family and is known to mediate signals of multiple cytokines that play a crucial role in immune and inflammatory signaling. Activation of TYK2 in tumor cells has been linked to promote cell survival, growth, and invasion. This study aimed to investigate the expression of tyrosine kinase 2 (TYK2) in colorectal cancer (CRC) and adjacent control tissues.

Oncolytic viruses in lung cancer treatment: a review article.

Lung cancer has a high morbidity rate worldwide due to its resistance to therapy. So new treatment options are needed to improve the outcomes of lung cancer treatment. This study aimed to evaluate the effectiveness of oncolytic viruses (OVs) as a new type of cancer treatment.

Microbiome modulation in inflammatory diseases: Progress to microbiome genetic engineering.

Recent developments in sequencing technology and analytical approaches have allowed researchers to show that the healthy gut microbiome is very varied and capable of performing a wide range of tasks. The importance of gut microbiota in controlling immunological, neurological, and endocrine function is becoming well-recognized. Thereby, numerous inflammatory diseases, including those that impact the gastrointestinal system, as well as less obvious ones, including Rheumatoid arthritis (RA), cancer, gestational diabetes (GD), type 1 diabetes (T1D), and type 2 diabetes (T2D), have been linked to dysbiotic gut microbiota.

Non-coding RNAs: A new frontier in benzene-mediated toxicity.

One of the most frequent environmental contaminants, benzene is still widely used as an industrial solvent around the world, especially in developing nations, posing a serious occupational risk. While the processes behind the toxicity of benzene grounds are not fully understood, it is generally accepted that its metabolism, which involves one or more reactive metabolites, is crucial to its toxicity. In order to evaluate the many ways that benzene could influence gene regulation and thus have an impact on human health, new methodologies have been created.

Diagnostic of Cytokeratin-19 Gene Expression in Iranian Breast Cancer Patients.

Sentinel lymph node (SLN) biopsy is currently the recommended procedure for axillary staging in clinically node-negative early breast cancer at diagnosis. The present study aimed to identify Cytokeratin-19 (CK19) gene profiles that accurately predicted the outcome of breast cancer patients. Fifty tumor samples from breast cancer patients were analyzed for the expression of the CK19 gene using quantitative PCR.

Evaluation of the current MicroRNAs expression levels as potential biomarkers in Oral Squamous Cell Carcinoma.

As the most common malignancy, oral squamous cell carcinoma (OSCC) is typically fatal. The survival of patients with oral cancer has not improved, and tumor recurrence remains high. During tumorigenesis, microRNAs (miRNAs) regulate gene expression.

Clinical and genetic characterization of neuronal ceroid lipofuscinoses (NCLs) in 29 Iranian patients: identification of 11 novel mutations.

Neuronal ceroid lipofuscinoses (NCLs) are neurodegenerative lysosomal storage diseases which are considered among the most frequent causes of dementia in childhood worldwide This study aimed to identify the gene variants, molecular etiologies, and clinical features in 23 unrelated Iranian families with NCL. In total, 29 patients with neuronal ceroid lipofuscinoses (NCLs), diagnosed based on clinical manifestations, MRI neuroimaging, and electroencephalography (EEG), were recruited for this study. Through whole-exome sequencing (WES), functional prediction, Sanger sequencing, and segregation analysis, we found that 12 patients (41.

Non-coding RNAs: An emerging player in particulate matter 2.5-mediated toxicity.

Exposure to air pollution has been connected to around seven million early deaths annually and also contributing to higher than 3 % of disability-adjusted lost life years. Particulate matters (PM) are among the key pollutants that directly discharged or formed due to atmospheric chemical interactions. Among these matters, due of its large surface area, PM2.

siRNA and targeted delivery systems in breast cancer therapy.

Recently, nucleic acid drugs have been considered as promising candidates in treatment of various diseases, especially cancer. Because of developing resistance to conventional chemotherapy, use of genetic tools in cancer therapy appears inevitable. siRNA is a RNAi tool with capacity of suppressing target gene.

An in silico comparative transcriptome analysis identifying hub lncRNAs and mRNAs in brain metastatic small cell lung cancer (SCLC).

Small cell lung cancer (SCLC) is a particularly lethal subtype of lung cancer. Metastatic lung tumours lead to most deaths from lung cancer. Predicting and preventing tumour metastasis is crucially essential for patient survivability.

Progress toward molecular therapy for diabetes mellitus: A focus on targeting inflammatory factors.

Diabetes mellitus (DM) has been the most prevalent global metabolic disease, turning into a serious risk for human health. Several researches have recorded a role for inflammation and immunity in the pathogenesis of both in T1DM and in T2DM. Lots of chemical agents are available to control and to cure diabetic patients, which are not always sufficient for euglycemia maintenance and late stage diabetic complications avoidance.

The Common miRNAs between Tuberculosis and Non-Small Cell Lung Cancer: A Critical Review.

Tuberculosis (TB) and non-small cell lung cancer (NSCLC) are two major contributors to mortality and morbidity worldwide. In this regard, TB and NSCLC have similar symptoms, and TB has symptoms that are identical to malignancy; therefore, sometimes it is mistakenly diagnosed as lung cancer. Moreover, patients with active pulmonary TB are at a higher risk of dying due to lung cancer.

Background: Epilepsy is a neurological disorder characterized by the potential to induce seizure and accompanied by cognitive, psychological, and social consequences. CACNA1A gene is a voltage-gated P/Q-type Cav2.1 channel that is broadly expressed in the central nervous system, and the pathogenic variants within this gene may be associated with the epileptic phenotype.

Altered expression of STAT genes in periodontitis.

Signal Transducer and Activator of Transcription (STAT) pathway is functionally located downstream of Janus kinases proteins and can integrate signals from diverse pathways, thus regulating several aspects of immune responses. Although contribution of STAT proteins in the pathogenesis of several inflammatory conditions has been confirmed, their role in the development of periodontitis has been less appraised. Thus, we assessed levels of STAT transcripts in the periodontal tissues and circulation of affected individuals compared with the corresponding controls.
