Gut microbe's metabolite butyrate hampers intestinal repair from IBD

Intestinal stem cells are among the most rapidly dividing cells in the body, busily creating new cells to replace the ones that are constantly being sloughed off. But unlike stem cells elsewhere in the body, those in the intestine are hidden away, and for good reason, it turns out.

Combining vitamin A with chemotherapy may offer promise for pancreatic cancer treatment

Around 8,800 people in the UK are diagnosed with pancreatic cancer each year. It is known as the UK's deadliest cancer, with a survival rate of just 3 per cent. Chemotherapy and radiotherapy alone are relatively unsuccessful in treating the disease, and while surgery to remove the tumour offers the best chance of survival, most patients are diagnosed when the cancer has already spread to other organs.

AKR1C3 enzyme could be promising therapeutic target for managing CRPC, AML

Prostate cancer is the second leading cause of mortality among American men with the highest incidence rate of all cancers reported in the U.S. Male sex hormones testosterone (T) and 5α-dihydrotestosterone (5α-DHT) promote prostate cancer progression.

Targeting ERK and compensatory pathways with drug inhibitors halts colorectal cancer growth

While investigating a potential therapeutic target for the ERK1 and 2 pathway, a widely expressed signaling molecule known to drive cancer growth in one third of patients with colorectal cancer, University of California San Diego School of Medicine researchers found that an alternative pathway immediately emerges when ERK1/2 is halted, thus allowing tumor cell proliferation to continue.

Biovica acquires cSens AB - creating opportunities for solving cancer diagnostic challenges

Biovica has acquired cSens AB, a company that has developed a PCR-based platform for the analysis of serum thymidine kinase (TK) enzyme activity, which correspond to tumor proliferation and cancer aggressiveness.

McGill researchers discover brain cells that play key role in leptin sensing, weight gain

It's rare for scientists to get what they describe as "clean" results without spending a lot of time repeating the same experiment over and over again. But when researchers saw the mice they were working with doubling their weight within a month or two, they knew they were on to something.

MUSC Hollings Cancer Center receives $8.9 million grant to explore signaling in sphingolipids

The Medical University of South Carolina's Hollings Cancer Center received an $8.9 million grant from the National Cancer Institute designed to foster collaboration across clinical and laboratory research for the study of signaling in sphingolipids, a class of lipids known to be involved in the growth of solid tumor cancers.

Study reveals new cell-signaling pathway that detects chromosome missegregation

A recent research study at The Hormel Institute, University of Minnesota is providing insight into the regulation of chromosome segregation and the mechanisms used by cells to prevent them from forming tumors.

Researchers identify 43 specific genes associated with both autism and cancer

Autism and cancer share more than 40 risk genes, suggesting that common mechanisms underlying the functions of some of these genes could conceivably be leveraged to develop therapies not just for cancer but for autism as well, an extensive assessment by researchers with the UC Davis MIND Institute and Comprehensive Cancer Center has found.

Key method to test compounds for anti-cancer activity in cells flawed, study reveals

The primary method used to test compounds for anti-cancer activity in cells is flawed, Vanderbilt University researchers report May 2 in Nature Methods. The findings cast doubt on methods used by the entire scientific enterprise and pharmaceutical industry to discover new cancer drugs.

Predictive statistical approach opens door to development of more effective therapies for breast cancer

Designing effective new drugs, especially drugs to fight cancer, demands that you know as much as you can about the molecular workings of cancer growth. Without that, it's like planning to fight a war against an enemy you've never seen.

Novel gene therapy can improve symptoms of Bubble Boy disease in young adults

Adolescents and young adults with a severe inherited immunodeficiency disorder improved following treatment with novel gene therapy developed at St. Jude Children's Research Hospital and at the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health. The results of this study appear today in the journal Science Translational Medicine.

MicroRNA controls tumor cell proliferation in most aggressive large B-cell lymphoma

A recent study by researchers at Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine showed that a microRNA called miR-181a dampens signals from the cancer-driving NFκB protein pathway in the most aggressive large B-cell lymphomas (DLBCL). By reducing NFκB signaling, miR-181a controls tumor cell proliferation and survival and could be the target of novel therapies. The study was published in the journal Blood.

Targeted therapies suppress T cell activity that could actually help fight tumors

In many cases, targeted therapies for cancer are preferred as treatments over chemotherapy and surgery because they attack and kill cancer cells with specific tumor-promoting mutations while sparing healthy, normal cells that do not express these mutations.

Cobimetinib with vemurafenib may have added benefit in melanoma with BRAF V600 mutation

Cobimetinib (trade name: Cotellic) has been approved since November 2015 in combination with vemurafenib for the treatment of adults with advanced, i.e. metastatic or unresectable, melanoma with a BRAF V600 mutation.

ROBO1 protein may delay progression of breast cancer

A protein called ROBO1 may delay the progression of breast cancer, according to a paper published in The Journal of Cell Biology. The study, "Loss of miR-203 regulates cell shape and matrix adhesion through ROBO1/Rac/FAK in response to stiffness" by Lily Thao-Nhi Le and colleagues, identifies a signaling pathway that may protect breast cells from the tumorigenic effects of stiff extracellular matrices.

Scientists find surprising link between iPS cell reprogramming, blood cell formation and cancer

The ability to reprogram cells has revolutionized stem cell research with major implications for almost all fields of modern biology. A decade ago Shinya Yamanaka described a procedure that revolutionized stem cell biology. Using a genetic trick that introduces a cocktail of four genes into cultured cells from human biopsies, he was able to generate induced pluripotent stem cells (iPS) from mature skin or blood cells

Alcohol consumption may increase risk for breast cancer

A University of Houston researcher and his team have discovered an important link between alcohol and breast cancer by identifying a cancer-causing gene triggered by alcohol

Multi-gene test can help identify early breast cancer patients who can safely be spared chemotherapy

Researchers have shown for the first time that it is possible to use a multi-gene test to identify patients with early breast cancer who can be spared chemotherapy and who will still be alive and well five years after diagnosis.

Delivering microRNAs in cancer treatment: an interview with Dr Conde and Prof Artzi

microRNAs (miRs) are small endogenous noncoding RNA molecules (20–23 nucleotides) derived from imperfectly paired hairpin RNA structures naturally encoded in the genome that act specifically as triggering molecules to control translational repression or mRNA degradation.
