Salk researchers develop new glioblastoma model using gene-edited organoids

Glioblastoma multiforme (GBM) is an incredibly deadly brain cancer and presents a serious black box challenge. It's virtually impossible to observe how these tumors operate in their natural environment and animal models don't always provide good answers.

Role of extrachromosomal pieces of DNA in cancer development and treatment resistance

Glioblastoma is the most common and aggressive form of brain cancer. Response to standard-of-care treatment is poor, with a two-year survival rate of only 15 percent.

Researchers develop highly specific apoptosis assay for pharmacodynamic analyses of tumor specimens

Existing microscopy-based methods of detecting apoptosis, such as TUNEL (terminal deoxynucleotidyl transferase dUTP nick-end labeling), have limited quantitative capabilities due to insufficient signal-to-noise ratios.

UCSF researchers find new way to attack common drivers of 'undruggable' cancers

Cancer researchers have made great strides in developing targeted therapies that treat the specific genetic mutations underlying a patient's cancer.

Enzyme inhibitor and chemotherapy combination regresses glioblastoma

In animal experiments, a human-derived glioblastoma significantly regressed when treated with the combination of an experimental enzyme inhibitor and the standard glioblastoma chemotherapy drug, temozolomide.

Prostate cancer’s gene-determined ‘immune landscape’ dictates tumor progression

The field of immunotherapy - the harnessing of patients' own immune systems to fend off cancer - is revolutionizing cancer treatment today. However, clinical trials often show marked improvements in only small subsets of patients, suggesting that as-yet unidentified variations among tumors result in distinct paths of disease progression and response to therapy.

Researchers identify novel mechanism that protects from brain tumor

A group of researchers at the Spanish National Cancer Research Centre have identified a protein called RanBP6 as a new regulator of EGFR. In a paper published in Nature Communications they show how silencing of RanBP6 promoted glioma growth, by upregulating EGFR expression.

Study provides new insights into mechanism of tumor survival in glioblastoma

A Northwestern Medicine study, published in the journal Cancer Cell, has provided new insights into a mechanism of tumor survival in glioblastoma and demonstrated that inhibiting the process could enhance the effects of radiation therapy.

High ADAR1 enzyme levels correlate with reduced survival rates in multiple myeloma

Multiple myeloma is the second most common blood cancer in the United States. Thirty to 50 percent of multiple myeloma patients have extra copies of the gene that encodes the enzyme ADAR1.

Researchers develop computer program to find new indications for old drugs

Researchers at the Case Comprehensive Cancer Center at Case Western Reserve University School of Medicine have developed a computer program to find new indications for old drugs.

Repositive introduces first Global PDX Directory at AACR conference

The first Global PDX Directory for proprietary and open source PDX models is being introduced by Cambridge (UK) based benefit corporation, Repositive, at the American Association for Cancer Research’sInternational Conference, on Molecular Targets and Cancer Therapeutics, hosted in conjunction with the European Organisation for Research and Treatment of Cancer and the National Cancer Institute, in Philadelphia, USA, 26-30 October 2017.

Research identifies molecular mechanism that causes kidney cancer to resist drug treatment

New research from The University of Texas Health Science Center at San Antonio and U.S. Department of Veterans Affairs has identified the molecular mechanism that causes kidney cancer to resist drug treatment.

Seventh Wave announces collaboration with Yecuris to study new liver disease therapies

Seventh Wave Laboratories, a consulting-based contract research organization that assesses the safety and efficacy of pharmaceutical products and medical devices, has announced an exclusive collaboration with Yecuris Corporation, a global leader in the development and use of humanized models in drug development research.

Researchers develop two-pronged approach to personalize breast cancer treatment

The goal of cancer therapy is to destroy the tumor or stop it from growing and spreading to other parts of the body.

Endostatin can decrease proliferation of castration-resistant prostate cancer cells

Failure of hormone deprivation therapy, which is used to slow prostate cancer in patients, leads to castration-resistant prostate cancer, a lethal form of advanced disease with limited treatment options.

DNA enhancers switch on colorectal cancer genes to promote tumor growth, study finds

Genetic mutations can increase a person's cancer risk, but other gene "enhancer" elements may also be responsible for disease progression, according to new research out of Case Western Reserve University School of Medicine.

Inactive B2M genes can condition response of lung cancer patients to immunotherapy, study shows

Researchers from the Genes and Cancer research group at the Bellvitge Biomedical Research Institute have identified inactivating mutations in a number of genes that code for HLA-I histocompatibility complex proteins, which are involved in the immune response and can condition the tesponse of lung cancer patients to immunotherapy.

Researchers identify attractive drug candidate to target glioma tumors

In a paper published today in Cancer Research, researchers: 1) identify a biomarker enzyme associated with aggressive glioma brain tumors, 2) reveal the regulatory mechanism for that enzyme, and 3) demonstrate potent efficacy, using a mouse model of glioma, for a small molecule inhibitor they have developed.

Cold medication could suppress spread of bladder cancers

Hokkaido University researchers have discovered that a nonsteroid anti-inflammatory drug used for treating colds suppresses the spread of bladder cancers and reduces their chemoresistance in mice, raising hopes of a future cure for advanced bladder cancers.
