This is the eighth most malignant tumor in the world, causing the highest incidence and malignancy rate of all cancers in the mouth and maxillofacial region. In cells, miRNAs regulate development, differentiation, proliferation, and differentiation, and miRNA expression is a better indicator of physiological status than DNA expression. miR-21, miR-132, miR-29a, miR-204, and miR-138 levels were measured in plasma from patients with primary OSCC and healthy controls.

Impulse oscillometry (IOS) is a method that does not depend on the cooperation of the patient and can detect small airway diseases with higher sensitivity than spirometry. However, the clinical application value of IOS in the screening of patients exposed to risk factors COPD and early diagnosis remains unclear. The aim of this study is to evaluate diagnostic sensitivity of IOS in the early detection of patients exposed to risk factors COPD.

The province of Khorasan-Razavi in the North East of Iran is an endemic area for anthroponotic cutaneous leishmaniasis (ACL caused mainly by ) and zoonotic cutaneous leishmaniasis (ZCL caused mainly by ). Based on clinical signs, some cities were considered as ACL foci while others were considered to be endemic for ZCL. This paper reviews studies performed on patients diagnosed with cutaneous leishmaniasis (CL) via the use of direct slide examination, ELISA, electrophoresis isoenzyme, RAPD PCR and PCR in Mashhad; the study also includes cases of CL in other cities of the Khorasan-Razavi province where only PCR used as a diagnostic tool.

Background: Early detection of cancers improves patients' survival and decreases the treatment cost. Unfortunately, the current methods for diagnosis of bladder and prostate cancers, two most common urothelial malignancies, suffer from a low sensitivity and specificity. MicroRNAs, as a group of endogenously produced non-coding RNAs, regulate gene expression and their expression is observed to be altered in many cancers and cancer progression phenomena.

In silico data analyses of the hotspot mutations of gene in choroideremia disease.

Data Brief

June 2018

Key Laboratory of Epigenetics and Oncology, Research Center for Preclinical Medicine, Southwest Medical University, Luzhou, Sichuan, China.

This data article provides compelling computational analysis of the hotspot gene mutations that contribute to the progressive causativeness and susceptibility of Choroideremia in patients. We performed structural and molecular dynamics (MD) simulation analysis on abnormal states of the CHM protein caused by deleterious and disease-causing hotspot mutant forms of CHM: S89C, E177K, and V529H. Within 40 ns, MD simulation time composed of the E177K mutant shows conformational alteration especially in several parts of the variant.

Choroideremia (CHM) is a rare form of X-linked chorioretinal dystrophy that is caused by mutations in the CHM gene. Mutations in the Rab escort protein-1 (REP-1), an ubiquitously encoded protein of the CHM gene, lead to prenylation and vesicle trafficking deficiency in the protein, resulting in the progressive degeneration of choriocapillaris, retinal pigment epithelium (RPE), and photoreceptors. Despite previous studies concerning this disease, no effective diagnostic tests or established therapeutic interventions currently exist for CHM.

Article Synopsis
  • - Stargardt disease-4 (STGD4) is a hereditary eye disorder that affects vision due to issues in the retina, and this study focuses on a specific genetic variant related to this condition in a Chinese family.
  • - Researchers discovered a new mutation (c.734T>C) in the PROM1 gene, which alters the protein in a way that likely disrupts its stability and functionality, contributing to the development of macular degeneration.
  • - The study's findings emphasize the importance of genetic testing for proper diagnosis and potential prevention strategies for those at risk of STGD4-like macular degeneration.

The diagnostic role of microRNA-34a in breast cancer: a systematic review and meta-analysis.

Oncotarget

April 2017

Key Laboratory of Epigenetics and Oncology, The Research Center for Precision Medicine, Southwest Medical University, Luzhou, Sichuan, PR China.

Background: MicroRNA-34a (miR-34a) is a master regulator of tumor suppression in breast cancer (BC). This systematic review aims to analyze the diagnostic accuracy of miR-34a in the detection of BC as a biomarker.

Results: A total of 1858 BC cases and 494 controls from thirteen eligible studies reported in 9 publications were included.

MicroRNA-34a (miR-34a) plays an essential role against tumorigenesis and progression of cancer metastasis. Here, we analyzed the expression, targets and functional effects of miR-34a on epithelial to mesenchymal transition-inducing transcription factors (EMT-TFs), such as TWIST1, SLUG and ZEB1/2, and an EMT-inducing protein NOTCH1 in breast cancer (BC) cell migration and invasion and its correlation with tumorigenesis and clinical outcomes. Expression of miR-34a is downregulated in human metastatic breast cancers (MBC) compared to normal breast tissues and is negatively correlated with clinicopathological features of MBC patients.

Sulfur mustard (SM) or mustard gas is a chemical alkylating agent that causes blisters in the skin (blister gas), burns the eyes and causes lung injury. Some major cellular pathways are involved in the damage caused by mustard gas such as NF-κb signaling, TGF-β signaling, WNT pathway, inflammation, DNA repair and apoptosis. MicroRNAs are non-coding small RNAs (19-25 nucleotides) that are involved in the regulation of gene expression and are found in two forms, extracellular and intracellular.

Purpose: Human Piwil2, a member of Piwi subfamily of Argonaute proteins, is primarily expressed in testis, where it regulates self-renewal of germ cells. However, its ectopic expression has been reported with several tumors, including breast cancer. The upregulation of piwil2 in various stages of breast cancer suggested its suitability as a novel tumor biomarker.

Background: Mesenchymal stem cells (MSCs) have been recently received increasing attention for cell-based therapy, especially in regenerative medicine. However, the low survival rate of these cells restricts their therapeutic applications. It is hypothesized that autophagy might play an important role in cellular homeostasis and survival.

Context: Sulfur mustard (SM), with extensive nucleophilic and alkylating properties, was employed during the Iran-Iraq war by Iraqi forces. The most critical complications attributed to SM are related to dangerous pulmonary disorders collectively known as "mustard lung". The symptoms gradually emerge over a long period, becoming chronic, and are dependent on time and the amount of exposed SM.

Aims: Coronary artery disease (CAD) is a major problem in some patients with type 2 diabetes mellitus (T2DM). CAD has been suggested to be the main result of reduced efficacy of DNA repair systems. Analysis of the DNA repair system in patients with diabetes can potentially uncover the molecular basis of their susceptibility to the CAD.

Background: Acute spinal cord injury (ASCI) can lead to paraplegia or quadriplegia, the treatment of which has been a major problem. New therapeutic approaches in developing carbon nanotubes (CNT) functionalized with the Nafion nanocomposite, a sulfonated tetrafluoroethylene copolymer, have been shown to increase the length of selected neurites in vitro.

Objective: We hypothesized that the administration of the CNT/Nafion nanocomposite after experimental SCI will promote regeneration of axons into the lesion cavity and the functional recovery of the hind limbs in a rat model.
