Diagnostic Significance of Hypomethylated and Genes in Patients with Colorectal Cancer.

Background: Colorectal cancer (CRC) has been often the main reason for dying worldwide. Many factors are implicated in the progress of colorectal carcinoma, one of the chiefs of which is DNA methylation.

A pair of 43 tumor and tumor-adjacent tissue biopsies obtained from GC patients, also 5 mL peripheral blood (following 12h fasting) were collected from the same patients and healthy controls (HCs).

Cytotoxic T-Lymphocyte Antigen-4 in Colorectal Cancer: Another Therapeutic Side of Capecitabine.

Cytotoxic T lymphocyte antigen-4 (CTLA-4) is an inhibitory immune checkpoint that can be expressed in tumor-infiltrating lymphocytes and colorectal cancer (CRC) cells. This immune checkpoint can attenuate anti-tumoral immune responses and facilitate tumor growth and metastasis. Although capecitabine is an effective chemotherapeutic agent for treating CRC, its effect on the tumoral CTLA-4 expression remains unclear.

The impact of microRNAs on myeloid-derived suppressor cells in cancer.

Inflammation promotes cancer development. To a large extent, this can be attributed to the recruitment of myeloid-derived suppressor cells (MDSCs) to tumors. These cells are known for establishing an immunosuppressive tumor microenvironment by suppressing T cell activities.

Circulating myeloid-derived suppressor cells: An independent prognostic factor in patients with breast cancer.

Evading immune destruction is a hallmark of cancer. Myeloid-derived suppressor cells (MDSCs), a heterogeneous population of myeloid immune cells, are thought to foster the establishment of an immunosuppressive tumor microenvironment, but it remains unclear how. This study aims to determine the levels of circulating MDSCs and their subpopulations and test their immunosuppressive functions in patients with breast cancer (BC).

Diagnostic Accuracy of a 64-Slice Multi-Detector CT Scan in the Preoperative Evaluation of Periampullary Neoplasms.

Deregulated expression of HDAC3 in colorectal cancer and its clinical significance.

Background: To date, 4 classes of histone deacetylases (HDACs) have been identified in humans. Class I HDACs are zinc-dependent and NAD+-independent enzymes, and include 4 isoforms closely related to yeast RPD3: HDAC1, 2, 3, and 8.

Objectives: The aims of the study were to quantitatively evaluate the expression of HDAC3 in colorectal cancer (CRC) and to correlate its expression levels with clinicopathological parameters.

Histone Deacetylase Inhibitor (Trapoxin A) Enhances Stemness Properties in Adipose Tissue Derived Mesenchymal Stem Cells.

Back Ground: Adipose tissue derived mesenchymal stem cells (ASCs) have unique potential for regenerative cell therapies. However, during ex-vivo cultivation, they undergo considerable quality loss regarding their phenotypic properties, stemness genes expression and differentiation potential. Recent studies reported that the loss of stemness properties of MSCs is a result of chromatin histone deacetylations through in-vitro cultivation.

mRNA expression of nuclear factor of activated T-cells, cytoplasmic 2 (NFATc2) and peroxisome proliferator-activated receptor gamma (PPARG) transcription factors in colorectal carcinoma.

Transcription factors are involved in cell cycle and apoptosis regulation and thus have a key role in the carcinogenesis of different tumors. Nuclear factor of activated T-cells, cytoplasmic 2 (NFATc2) and peroxisome proliferator-activated receptor gamma (PPARG) transcription factors are important in the carcinogenesis of colorectal cancer (CRC). In this study, we examined whether the expression of NFATc2 and PPARG genes is significantly altered during the carcinogenesis of CRC.
