The aim of the present study was to investigate the reproductive behavior of the giant Amazon River turtle (Podocnemis expansa) in the Amazon. This was carried out by estimating the degree of polymorphism in five DNA microsatellites in a sample of 359 hatchlings from 12 nests in the Mamirauá Sustainable Development Reserve in the municipality of Tefé, state of Amazonas, Brazil. An analysis of ... more

Buffalo production is spreading globally because of its economic advantage. Then, it has become necessary to improve the reproductive and productive efficiency of these animals, as well as to look for genetic factors that increase this efficiency. The objectives of this study were to characterize the promoter region of the melatonin 1A receptor gene (MTRN1A), to detect possible SNPs and ... more

Prostate cancer is a common malignancy of the male reproductive-urinary system. MDM2 is an oncogene, whose expression can be regulated by microRNA (miRNA). The present study investigated the expression and correlation of miRNA-509-5p and MDM2 to determine the mechanism of their function in invasion and migration of prostate cancer cells. RT-PCR was performed to detect the expression of miRNA- ... more

Ankylosing spondylitis (AS), a progressive disease of the spine, manifests as peripheral arthritis with tendon and ligament inflammation that restricts activity. AS is a rheumatoid autoimmune disease although the rheumatoid factor is absent in patients with AS. It is characterized by inflammatory changes such as elevated levels of serum inflammatory factors. The roles of Th1 and Th2 cytokines ... more

Human papillomavirus (HPV) infection is considered a risk factor for cervical cancer. Even if the high-risk HPV (HR-HPV) infection is necessary, environmental co-factors and genetic susceptibility also play an important role in cervical cancer development. In this study, a possible association of rs1695 GSTP1 polymorphisms, HR-HPV infection, and oral contraceptive use with cancer lesion ... more

In chronic myeloid leukemia (CML) two main types of messenger RNA (e14a2 and e13a2) can be produced by BCR-ABL1 gene rearrangement. Due to conflicting results, the clinical value of these transcripts remains controversial. The aim of this study was to identify associations of e14a2 and e13a2 transcripts with laboratory variables and also the response to treatment. This study included 203 adult ... more

We aimed to analyze gastric signet ring cell (SRC) carcinoma subtypes by investigating gastric and intestinal phenotypic marker expression, and explore the relationship between phenotype and K-ras mutation. Immunohistochemistry was performed on 163 SRC carcinoma patient specimens to detect gastric (MUC1, MUC5AC, and MUC6) and intestinal (MUC2 and CDX2) phenotypic markers, and tumors were ... more

The mRNA expression of cell adhesion molecule 1 (CADM1) and its clinicopathological significance in esophageal squamous cell carcinoma (ESCC) tissues were investigated. CADM1 mRNA and protein expression were detected in tissue samples from 50 patients with ESCC by reverse transcription-polymerase chain reaction (RT-PCR) and streptavidin-peroxidase (SP) immunohistochemistry; adjacent tissues ... more

Knee osteoarthritis (KOA) is a common degenerative joint disease and immune system dysregulation has been implicated in its pathogenesis. The effect of arthroscopic knee surgery, an important method for KOA diagnosis and treatment, on the expression of immune regulators remains poorly understood. We aimed to investigate the clinical efficacy of such surgery and its impact on IL-1β, CXCL13, and ... more

Congenital deafness is a serious and irreversible condition in humans. The GJB2 gene is implicated in the pathogenesis of autosomal recessive nonsyndromic hearing loss. Its 235delC and 30-35delG polymorphisms are reported to be associated with risk of hereditary deafness. However, the effect of the interaction between GJB2 235delC and 30-35delG and environmental factors on congenital deafness ... more
