The results of the study, published in Science, are revealing and help to understand more about the functions of this essential protein which stops the formation of tumours and therefore could open the door to new approaches in the study of cancer. (scienceblog.com)

Specific tissue miRs are shown to be promising prognostic biomarkers in patients with CRC, given their strong association with the prognostic aspects of these tumors, however, new studies are necessary to establish the sensibility and specificity of the miRs in order to use them in clinical practice.

In the past decade, many clinical trials have been investigating anti-CTLA-4 as well as anti-programmed cell death protein 1 (PD-1) therapies in various solid tumors, including HCC. (stanford.edu)
The studies related to tumor biological and clinical features in adults are limited due to the low incidence of the disease in this age group. (surgicalneurologyint.com)

This heterodimer of HIF activates genes that encode for proteins such as vascular endothelial growth factor (VEGF) and erythropoietin, proteins that are both involved in angiogenesis. (standardofcare.com)
