Using ribosomal protein expression patterns as cancer biomarker

A research team at the University of Basel’s Biozentrum has investigated the expression of ribosomal proteins in a wide range of human tissues including tumors and discovered a cancer type specific signature. The study is reported in journal Genome Biology. Researchers think that these signature could be used for predicting progression and survival. Gene expression level of individual …

New lung cancer biomarker Protein PD-1 for predicting survival

The biomarker PD-1, a protein, could potentially be used to predict survival or disease-free survival of lung cancer patients who have had the tumor surgically removed. This is substantiated by the results of a study conducted under the direction of the Comprehensive Cancer Center (CCC) of MedUni Vienna and Vienna General Hospital, together with MedUni …

Research shows possible link between "body clock" and cancer pathogenesis

A new study led by scientists at The Scripps Research Institute (TSRI) describes an unexpected role for proteins involved with our daily “circadian” clocks in influencing cancer growth. The research, published in the journal Molecular Cell, suggests that disruptions in circadian rhythms might leave levels of an important cancer-linked protein, called cMYC, unchecked. “This appears …

Lab study shows how metformin can protect against cancer

Researchers at University of California San Diego School of Medicine have identified a previously unknown mechanism that helps fortify the structure and tight junctions between epithelial cells, a basic cell type that lines various body cavities and organs throughout the body, forming a protective barrier against toxins, pathogens, and inflammatory triggers. Breaches of this barrier …

Protein CPEB4 plays crucial role in melanoma

Spanish National Cancer Research Centre (CNIO) Melanoma Group researchers work tirelessly to identify biomarkers of tumor progression and to validate novel therapeutic targets in melanoma. In particular, their research focuses on discovering features that define the “fingerprint” of this tumor, features that distinguish it from other cancer types. The latest study in this area, published …

Over expression of protein BRD4 associated with breast cancer metastasis

Researchers have identified a new pathway and with it a protein, BRD4, necessary for breast cancer cells to spread. The findings, which appear in the journal Cancer Research, may provide a new target to suppress breast cancer metastasis. Triple-negative breast cancer is considered the worst subgroup of breast cancer. It is highly aggressive and responds …
