Liver cirrhosis (LC) is a heterogeneous liver disease, the last stage of liver fibrosis, and the major risk factor for hepatocellular carcinoma (HCC). Our study aimed to evaluate the expression of microRNAs and the endothelial vascular growth factor (VEGFA) gene in LC and HCC. ⋯ Overexpression of VEGFA in LC suggests impairment of angiogenesis in this tissue. The differential expression of microRNAs in LC and HCC observed in our study can lead to the evaluation of possible biomarkers for these diseases.

Bladder transitional cell carcinoma (BTCC) is one of the most prevalent human malignant diseases. Gemcitabine is commonly applied in the treatment of BTCC while acquired gemcitabine resistance has caused a severe impediment to recovery. This study aimed to investigate the function of DRAM2 in regulating gemcitabine resistance of BTCC. ⋯ Our data suggested that downregulation of DRAM2 rescued the sensitivity of T24-GEM cells to gemcitabine, providing an appropriate therapeutic target for BTCC treatment.

We examined the association between sarco/endoplasmic reticulum calcium ATPase (SERCA) expression and glycated hemoglobin (HbA1c) levels since alterations in this protein expression are associated with the genesis of insulin resistance. HbA1c levels and SERCA protein expression from platelets of Mexican patients diagnosed with type 2 diabetes mellitus (T2DM) were analyzed showing lower values of SERCA expression against the normal values we find in healthy people. Interestingly, as diabetes condition got worse; SERCA protein expression decreased gradually until it was undetectable. The results showed an inverse correlation between HbA1c and SERCA protein expression in T2DM patients. .

The aim of this study was to evaluate 3-dimensional (3D) ultrasonography (US) in determining the surface irregularity of carotid artery plaques. ⋯ The present study shows that 3D US examination is a valuable non-invasive method for investigation of surface irregularity of carotid artery plaques.

The aim of the current study was to identify whether serum pentraxin 3 (PTX3) level could be a marker of increased inflammation in rheumatoid arthritis (RA) patients. ⋯ No relationship was determined between PTX3 and disease activity in RA patients, nor with traditional clinical and biochemical measurements of disease activity. However, the PTX3 levels of the RA patients were found to be high in comparison with the control group. Because, from these results, the role of PTX3 in the pathogenesis of RA cannot be ignored, there is a need for further studies to determine the potential role of PTX3 in RA pathogenesis.
