Small RNA plays big role suppressing cancer

Researchers at UC Davis have unraveled some of these relationships, identifying several interactions that directly impact liver and colon cancer. The work provides new insights into how miR-22 operates and could potentially lead to new cancer therapies. The study was published in the Journal of Biological Chemistry. “There are quite a few molecules present in […]

Strong grasp of immune response dynamics will enhance checkpoint blockade

“Identifying in advance who will benefit from treatment and developing combination therapies to improve and expand on current results will require us to decipher the dynamics of human immune response to tumors and their surrounding microenvironment,” said co-author Padmanee Sharma, M.D., Ph.D., professor of Genitourinary Medical Oncology and Immunology at The University of Texas MD […]

Herpesvirus activates RIG-I receptor to evade body’s immune system

Led by Pinghui Feng, Ph.D., associate professor of molecular microbiology and immunology at the Keck School of Medicine of USC, the team found that herpesvirus proteins activate retinoic acid-induced gene I (RIG-I) by removal of an amino group from the glutamine and asparagine amino acids through a process called deamidation. RIG-I is a cellular receptor […]

Possible progress against Parkinson’s and good news for stem cell therapies

Parkinson’s, which affect as many 10 million people in the world, is caused by a depletion of dopamine-producing neurons in the brain. Current treatments include medications and electrical implants in the brain which causes severe adverse effects over time and fail to prevent disease progression. Several studies have indicated that the transplantation of embryonic stem […]

Cancer genes turned off in deadly brain cancer

While standard chemotherapy drugs damage DNA to stop cancer cells from reproducing, the new method stops the source that creates those cancer cells: genes that are overexpressing certain proteins. “Our study identified miR-182 as a glioblastoma tumor suppressor that reduces the expression of several oncogenes that promote cancer development,” said senior author of the study […]

One dollar blood test using gold nanoparticles outperforms PSA screen for prostate cancer, study suggests

The simple test developed by University of Central Florida scientist Qun “Treen” Huo holds the promise of earlier detection of one of the deadliest cancers among men. It would also reduce the number of unnecessary and invasive biopsies stemming from the less precise PSA test that’s now used. “It’s fantastic,” said Dr. Inoel Rivera, a […]

Research aims to reduce health care disparities

Gwendolyn P. Quinn, Ph.D., scientific director of the Survey Methods Core Facility at Moffitt, identified physicians largely operate under a, “don’t ask, don’t tell” policy that prohibits open and honest dialogue between doctor and patient about cancer risk. The study highlights that LGBTQI populations face barriers to health insurance such as when partnerships and marriages are not legally recognized; concerns about disclosure in a health care setting, discrimination, misconceptions, legal and financial barriers and the disenfranchised stress and distress of caregiving same-sex partners. …

Bio-marker set forms the basis for new blood test to detect colorectal cancer

Max Mazzone (VIB/KU Leuven): “This research demonstrates how important it is to gain a thorough understanding of the role of our immune system in cancer. In this case, this knowledge will hopefully result in a new, more sensitive test to detect colorectal cancer at an early stage, so that more patients can be cured. I hope that we can soon find an industrial partner to help us achieve the following step, which is the development of the test.” Colorectal cancer: a growing medical problem In 2012, a total of 1.4 million people worldwide were diagnosed with colorectal cancer, this figure is expected to increase to 2.4 million by 2035. This is a condition that affects a growing number of people each year. …
