Scientists identify protein that could serve as a therapeutic target in lung cancer
(<i>Virginia Commonwealth University</i>) A new study led by scientists at VCU Massey Cancer Center suggests that gain-of-function mutations turn p53 into an oncogene, causing cells to replicate uncontrollably and contribute to cancer development. Recently published in Nature Communications, the researchers determined that mutant p53 genes are empowered by a specific protein, PLK3, to copy their genetic code and promote tumor cell proliferation through a process called transactivation.

POT1 gene mutation predisposes to glioma and affects survival in a sex-specific manner

Novel drug regenerates erectile nerves damaged by prostate surgery
(<i>Albert Einstein College of Medicine</i>) Researchers at Albert Einstein College of Medicine have developed a topical drug that regenerates and restores the function of erectile nerves damaged by radical prostatectomy, the most common treatment for localized prostate cancer. The drug was tested in rats, and the findings were published online today in JCI Insight.

Bone microenvironment fosters breast cancer metastatic behavior
(<i>Baylor College of Medicine</i>) The bone microenvironment reduced ER expression in ER+ breast cancer cells and triggered reprogramming that promoted the cancer cells' ability to metastasize.

Research sheds new light on pancreatic cancer metastasis
(<i>University of Oklahoma</i>) A team of researchers at the OU College of Medicine has published a new study in the journal Gastroenterology, the world's leading publication on GI tract disease, that sheds new light on the ability of pancreatic cancer cells to spread throughout the body. Understanding why metastasis occurs is crucial for developing a therapeutic strategy to stop the spread.

University of Colorado inter-campus collaboration wins R01 award for salivary gland cancer
(<i>University of Colorado Anschutz Medical Campus</i>) Two University of Colorado Cancer Center researchers have received a five-year R01 Award for $497,893 per year from the National Institutes of Health (NIH) to study a potential new drug treatment for salivary gland cancer. The award is part of an inter-campus collaboration between Antonio Jimeno, MD, Ph.D., co-leader of the Developmental Therapeutics Program, and Tin Tin Su, Ph.D., co-leader of the Molecular and Cellular Oncology Program.

Philanthropy-backed accelerator advances cancer therapies
(<i>Dartmouth College</i>) An initiative launched by Norris Cotton Cancer Center and the Magnuson Center for Entrepreneurship to bring new cancer treatments to patients more quickly makes its inaugural award announcment.

An antibody-drug combo to combat cancer
(<i>Tokyo Medical and Dental University</i>) Researchers at Tokyo Medical and Dental University (TMDU) have developed an ingenious therapeutic strategy against chronic myelomonocytic leukemia that links a cytotoxic drug payload to an antibody vector that targets the CD64 marker highly expressed by monocytes and monocytic progenitors. This selective antibody-drug conjugate spares other blood cell lineages thus avoiding the side-effects of conventional anti-cancer drugs such as anemia, infection or bleeding diatheses. Consequently, this drug-delivery tactic shows great promise against other monocyte-related diseases.

CNIO researchers explain the toxicity of USP7 inhibitors, under development for cancer treatment
(<i>Centro Nacional de Investigaciones Oncológicas (CNIO)</i>) The researchers have discovered that USP7 inhibitors -under development by several pharmaceutical companies for the treatment of cancer- trigger a premature activation of cell cycle proteins, leading to uncontrolled cancer cell division and death.* The paper rejects the premise that the therapeutic efficacy of these inhibitors is due to their effects on activating the tumor suppressor protein P53, as currently accepted by the international scientific community. These results extend the potential use of USP7 inhibitors to a wider range of patients.

Science Advances publishes proteomics technology from Oblique Therapeutics AB
(<i>Oblique Therapeutics</i>) Oblique Therapeutics AB, a Sweden-based biotech company, in collaboration with Karolinska Institutet (Stockholm, Sweden), Gothenburg University (Sweden) and several local biotechs published promising research results in the highly-acclaimed scientific journal Science Advances (AAAS) entitled: Rational Antibody design for Undruggable Targets using Kinetically Controlled Biomolecular probes.

City of Hope's Betty Ferrell receives 2021 ONS Lifetime Achievement Award
(<i>City of Hope</i>) With nearly half a century of outstanding contributions to the field of oncology nursing, City of Hope's Betty Ferrell, PhD, MA, CHPN, FAAN, FPCN, was selected by the ONS Board of Directors to receive the society's 2021 Lifetime Achievement Award. Ferrell is the director of the division of nursing research and education at City of Hope, principal investigator of the End-of-Life Nursing Education Consortium (ELNEC) project, and a world-renowned author and lecturer.

Unlocking new avenues for curing cancer: Cell receptor neuropilin-1 could hold the key
(<i>Cactus Communications</i>) Scientists have been exploring the cellular mechanisms underlying cancers for centuries in an attempt to successfully treat them. Collating recent research on one avenue of this exploration, the role of cell membrane receptor neuropilin-1, a review article published in Chinese Medical Journal gives a glimpse of how much we know of the disease, how much we still need to find out, and new promising treatments that we've begun to apply.

Study: New approach may boost prostate cancer immunotherapies
(<i>Cedars-Sinai Medical Center</i>) Researchers have discovered a new way to transform the tissues surrounding prostate tumors to help the body's immune cells fight the cancer.

Findings have implications in enhancing cellular response to radiation and chemotherapy.

Long-term survival rates for immunotherapies could be misinterpreted
(<i>Vanderbilt University Medical Center</i>) Immune checkpoint inhibitors have transformed cancer care to the point where the popular Cox proportional-hazards model provides misleading estimates of the treatment effect, according to a new study published April 15 in JAMA Oncology.

An ion pump to deliver chemotherapy agents to the brain
(<i>Linköping University</i>) Despite surgery and subsequent treatment with chemotherapy and radiation, the majority of patients experience recurrence of malignant brain tumours. Researchers at Linköping University, Sweden, and the Medical University of Graz, Austria, have shown in cells in culture that an ion pump can deliver drugs more accurately, which gives less severe adverse effects in chemotherapy. The results have been published in Advanced Materials Technologies.
