The high FKBP1A expression in WBCs as a potential screening biomarker for pancreatic cancer.

Given the limitation of current routine approaches for pancreatic cancer screening and detection, the mortality rate of pancreatic cancer cases is still critical. The development of blood-based molecular biomarkers for pancreatic cancer screening and early detection which provide less-invasive, high-sensitivity, and cost-effective, is urgently needed. The goal of this study is to identify and validate the potential molecular biomarkers in white blood cells (WBCs) of pancreatic cancer patients.

Changes in immune cell subtypes during ageing.

Background: The immune system comprises many different types of cells, each with different functions and properties during immune defence. The numbers and types of immune cells in the circulation is highly dynamic and regulated by infections, ageing and certain types of cancers. It is recognised that immune function decreases during ageing, but the biological age at which these functional changes occur is variable, and how ageing affects the different sub-types of lymphocytes, monocytes and NK cells in the circulation is not fully defined.

New Phenolic Glycosides from Lindl. var. and Their Cytotoxicity against Human Breast Cancer Cells.

The phytochemical investigation of the whole plants of Lindl. var. led to the discovery of three new phenolic glycosides, i.

Upregulation of p16INK4A in Peripheral White Blood Cells as a Novel Screening Marker for Colorectal Carcinoma.

Objective: Screening of colorectal cancer (CRC) is important for the early detection. CRC is relating to aging and immuno-senescence. One such senescent marker is p16INK4A expression in immune cells.

Breast Cancer Sera Changes in Alu Element Methylation Predict Metastatic Disease Progression.

Background/aim: During metastatic disease development, the cancer-immune system crosstalk induces epigenetic modifications to immune cells, impairing their functions. Recently, Alu elements methylation changes were widely studied in terms of early cancer detection. This study aimed to demonstrate in vitro Alu element methylation changes in peripheral immune cells in a metastatic setting and examine their prognostic values in metastatic breast cancer.

The roles of HMGB1-produced DNA gaps in DNA protection and aging biomarker reversal.

The endogenous DNA damage triggering an aging progression in the elderly is prevented in the youth, probably by naturally occurring DNA gaps. Decreased DNA gaps are found during chronological aging in yeast. So we named the gaps "Youth-DNA-GAPs.

The expression of FLNA and CLU in PBMCs as a novel screening marker for hepatocellular carcinoma.

Early detection improves survival and increases curative probability in hepatocellular carcinoma (HCC). Peripheral blood mononuclear cells (PBMCs) can provide an inexpensive, less-invasive and highly accurate method. The objective of this study is to find the potential marker for HCC screening, utilizing gene expression of the PBMCs.

Quantitative STAU2 measurement in lymphocytes for breast cancer risk assessment.

Although mammograms play a key role in early breast cancer detection, the test is not applicable to all women, for example, women under the age of 40. The development of a noninvasive blood test with high sensitivity and accessibility will improve the effectiveness of breast cancer screening programmes. Secretory factors released from cancer cells can induce the expression of certain genes in a large number of white blood cells (WBCs).

Tumor-induced DNA methylation in the white blood cells of patients with colorectal cancer.

The secretions of cancer cells alter epigenetic regulation in cancer stromal cells. The present study investigated the methylation changes in white blood cells (WBCs) caused by the secretions of colorectal cancer (CRC) cells. Changes in the DNA methylation of peripheral blood mononuclear cells (PBMCs) from normal individuals co-cultured with CRC cells were estimated using a methylation microarray.

Breast cancer upregulating genes in stromal cells by LINE-1 hypermethylation and micrometastatic detection.

Unlabelled: Changes in the methylation level of genes containing LINE-1 alter host gene regulation.

Aim: This study demonstrates that paracrine signaling of breast cancer influences the epigenetic regulation of stromal cells.

Methods: We proved in vitro and in vivo breast cancer promoted LINE-1 methylation exists exclusively in female stromal cells.

Alu methylation in serum from patients with nasopharyngeal carcinoma.

Background: Nasopharyngeal carcinoma (NPC) is a common cancer in Southern China and Southeast Asia. Alu elements are among the most prevalent repetitive sequences and constitute 11% of the human genome. Although Alu methylation has been evaluated in many types of cancer, few studies have examined the levels of this modification in serum from NPC patients.

Alu hypomethylation in smoke-exposed epithelia and oral squamous carcinoma.

Background: Alu elements are one of the most common repetitive sequences that now constitute more than 10% of the human genome and potential targets for epigenetic alterations. Correspondingly, methylation of these elements can result in a genome-wide event that may have an impact in cancer. However, studies investigating the genome-wide status of Alu methylation in cancer remain limited.

Synthesis and theoretical study of molecularly imprinted nanospheres for recognition of tocopherols.

Molecular imprinting is a technology that facilitates the production of artificial receptors toward compounds of interest. The molecularly imprinted polymers act as artificial antibodies, artificial receptors, or artificial enzymes with the added benefit over their biological counterparts of being highly durable. In this study, we prepared molecularly imprinted polymers for the purpose of binding specifically to tocopherol (vitamin E) and its derivative, tocopherol acetate.
