miRNAs have been involved in the pathogenesis of several cancers such as gastric cancer (GC.). In the following study we analyzed the expression of miR-7 in gastric cancer samples compared non-tumor tissues and gastric dysplasia (GD) samples with patients’ clinico-pathological data and its potential as diagnostic biomarker. We first analyzed its exp.. Read More»

Renal transplantation provides a significant increase in life expectancy for patients with end-stage kidney diseases. Despite the unequivocal progresses made in the last decades, many grafts injuries still jeopardize graft function leading to its loss. Currently, the allograft biopsy is the gold standard for diagnosing such conditions. However, it has man.. Read More»

Purpose: Epigenetic changes can be detected in precancerous lesions, suggesting that may be involved in the early stages of carcinogenesis. The methylation of specifics genes has been correlated with the outcome of many different types of cancers. This study compared the levels of DNA methylation between normal and tumor tissu..

Myelodysplastic syndrome diagnosis of karyotypically normal patients may be elusive because it relies exclusively on morphological and clinical data. In routine practice, finding of an acquired mutation or a cytogenetic abnormality provides irrefutable evidence of the clonal nature of that disease. Recurrent deletions and soma.. Read More»

Chronic obstructive pulmonary disease (COPD) is a growing cause of morbidity and mortality throughout the world. The purpose of our study was to uncover biomarkers and explore its pathogenic mechanisms at the molecular level. The gene expression profiles of COPD samples and normal controls were downloaded from Gene Expression Omnibus. Matlab was used for .. Read More»

To bring about improvements in cancer biology research and elucidate mechanism-based therapeutic targets, we studied the proteome expression profile of purified normal urothelial cells (cancer cells) and normal stromal cells (cancerous stromal cells). Based on the expression profile, biomarker discovery and the mechanisms of multi-step carcinogenesis were.. Read More»

The grey hamster has been used in biomedical research for decades. However, effective molecular methods for evaluating the genetic structure of this species are lacking, which hinders its wider usage. In this study, we employed cross-amplification of microsatellite loci of species within the same genus by polymerase chain reaction. Loci screened included .. Read More»

We investigated weak cation magnetic separation technology and matrix-assisted laser desorption ionization-time of flight-mass spectrometry (MALDI-TOF-MS) in screening serum protein markers of primary type I osteoporosis. We selected 16 postmenopausal women with osteoporosis and nine postmenopausal women as controls to find a .. Read More»

We investigated the differences between the serum proteomic spectral characteristics of acute myeloid leukemia (AML) patients and those of healthy people. We collected peripheral blood serum samples from 62 AML patients and 15 healthy controls. After removing high-abundance proteins, low-abundance serum proteins were separated.. Read More»

We examined the expression of angiopoietin-2 in serum samples from patients diagnosed with colorectal cancer and healthy volunteers and investigated the feasibility of using angiopoietin-2 as a potential diagnostic colorectal cancer biomarker. Enzyme-linked immunosorbent assays were used to measure the levels of angiopoietin-2.. Read More»
