  • Managing Cancer Care during the COVID-19 Pandemic and Beyond.
    Trends Cancer (IF 11.093) Pub Date : 2020-04-27
    Omar Alhalabi,Vivek Subbiah

    The coronavirus disease 2019 (COVID-19) pandemic is posing insurmountable challenges to healthcare systems globally. Cancer therapy is complex, and outcomes are centered on timing. Many oncology societies and health ministries have issued guidelines for cancer care to enable oncologists and patients to navigate the crisis. Lessons learned should inform care models for future pandemics.

    COVID-19 has had a devastating impact on the care of cancer patients. Thus, tele-oncology has become a necessity to improve cancer care. Several organisations have issued guidelines for its use during COVID-19. Despite certain shortcomings, tele-oncology has great potential to help cancer patients during COVID-19 and in the future.

    Despite their ubiquitous expression, the inheritance of monoallelic germline mutations in breast cancer susceptibility gene type 1 or 2 (BRCA1/2) poses tissue-specific variations in cancer risks and primarily associate with familial breast and ovarian cancers. The molecular basis of this tissue-specific tumor incidence remains unknown and intriguing to cancer researchers. A plethora of recent reports

    Increased physical activity reduces cancer risk in humans, but why this whole-organism attribute reduces cancer remains unclear. Active individuals tend to have high capacity to generate energy on a sustained basis, which in turn can permit greater immune responses crucial for fighting emerging neoplasia. Thus, we suggest energetic capacity as a potential mechanism to explain the activity–cancer link

    Chemotherapy is central to oncology, perceived to operate only on prolific cancerous tissue. Yet, many non-neoplastic tissues are more prolific compared with typical tumors. Chemotherapies achieve sufficient therapeutic windows to exert antineoplastic activity because they are prodrugs that are bioactivated in cancer-specific environments.

    Pediatric cancer is a leading cause of death in children and adolescents. Improvements in pediatric cancer treatment that include the alleviation of long-term adverse effects require a deeper understanding of the genetic, epigenetic, and developmental factors driving these cancers. Here, we review how the unique attributes of the zebrafish model system in embryology, imaging, and scalability have been

  • Perturbation-Driven Entropy as a Source of Cancer Cell Heterogeneity.
    Trends Cancer (IF 11.093) Pub Date : 2020-03-13
    Sebastian M B Nijman

    Intratumor heterogeneity is a key hallmark of cancer that contributes to progression and therapeutic resistance. Phenotypic heterogeneity is in part caused by Darwinian selection of subclones that arise by random (epi)genetic aberrations. In addition, cancer cells are endowed with increased cellular plasticity compared with their normal counterparts, further adding to their heterogeneous behavior.

  • PD1 Blockade in Cancer: Impact on Myeloid Cells.
    Trends Cancer (IF 11.093) Pub Date : 2020-03-13
    Mai Fujiwara,Lucien P Garo,Gopal Murugaiyan

    Programmed death 1 (PD1) has emerged as a major inhibitor of antitumor T cells, and anti-PD1 therapies have demonstrated clinical efficacy in multiple cancers. However, the impact of PD1 on other immune cells had remained unclear. A recent study by Strauss et al. describes how myeloid cell-intrinsic PD1 signaling limits myelopoiesis in cancer pertinent to anti-PD1 therapies.

  • On a New Proposed Mechanism of 5-Fluorouracil-Mediated Cytotoxicity.
    Trends Cancer (IF 11.093) Pub Date : 2020-03-13
    Shobbir Hussain

    The major molecular mode of action of the cytotoxic drug 5-fluorouracil (5-FU) is generally considered to result from thymidylate synthase inhibition. Recent findings relating to the function of the human uracil-5 methyltransferase (U5MT), TRMT2A, and its interaction with 5-FU metabolites incorporated within tRNAs, lead to an additional hypothesis that is proposed here.

  • Treating the Disease, Not the Symptom: Beyond NSAIDs.
    Trends Cancer (IF 11.093) Pub Date : 2020-03-12
    Robert R Bowers,Joe R Delaney,Demetri D Spyropoulos

    Mitigating inflammation is clearly important in cancer prevention and control. Traditionally, pharmaceuticals have taken the lead in this problem. In an attempt to 'head them off at the pass', this Forum takes a hard look at the concept of 'better living through chemicals' and limiting proinflammatory chemicals entering the body.

  • Redox Debt Leads to Metabolic Bankruptcy in Tumors.
    Trends Cancer (IF 11.093) Pub Date : 2020-03-06
    Evan Quon,Madeleine L Hart,Lucas B Sullivan

    Lactate dehydrogenase (LDH) accounts for the fermentative component of aerobic glycolysis, a near ubiquitous metabolic alteration in cancer. Recently, Oshima et al. developed a bioavailable LDH inhibitor that decreases tumor growth in mice and functions synergistically with mitochondrial respiration inhibitors. These findings suggest a cooperative mechanism of action that targets redox homeostasis

  • Towards the Microbial Production of Plant-Derived Anticancer Drugs.
    Trends Cancer (IF 11.093) Pub Date : 2020-03-05
    Vincent Courdavault,Sarah E O'Connor,Audrey Oudin,Sébastien Besseau,Nicolas Papon

    Many of the plant-derived compounds used in chemotherapies are currently produced by semisynthesis, which results in limited supplies at exorbitant market prices. However, the synthetic biology era, which began ca 15 years ago, has progressively yielded encouraging advances by using engineered microbes for the practical production of cheaper plant anticancer drugs.

  • Promoter DNA Hypermethylation and Paradoxical Gene Activation.
    Trends Cancer (IF 11.093) Pub Date : 2020-03-04
    Jim Smith,Swapnoleena Sen,Robert J Weeks,Michael R Eccles,Aniruddha Chatterjee

    DNA methylation is a stable epigenetic modification that contributes to the spatiotemporal regulation of gene expression. The manner in which DNA methylation contributes to transcriptional control is dependent on the biological context, including physiological state and the properties of the DNA itself. Classically, dense promoter DNA methylation is associated with transcriptional repression. However

  • Tumor Plasticity and Resistance to Immunotherapy.
    Trends Cancer (IF 11.093) Pub Date : 2020-03-04
    Lucas A Horn,Kristen Fousek,Claudia Palena

    Tumor cell plasticity exhibited as an epithelial-mesenchymal transition (EMT) has been identified as a major obstacle for the effective treatment of many cancers. This process, which involves the dedifferentiation of epithelial tumor cells towards a motile, metastatic, and mesenchymal tumor phenotype, mediates resistance to conventional therapies and small-molecule targeted therapies. In this review

  • The Mystery of Rap1 Suppression of Oncogenic Ras.
    Trends Cancer (IF 11.093) Pub Date : 2020-03-02
    Ruth Nussinov,Hyunbum Jang,Mingzhen Zhang,Chung-Jung Tsai,Anna A Sablina

    Decades ago, Rap1, a small GTPase very similar to Ras, was observed to suppress oncogenic Ras phenotype, reverting its transformation. The proposed reason, persisting since, has been competition between Ras and Rap1 for a common target. Yet, none was found. There was also Rap1's puzzling suppression of Raf-1 versus activation of BRAF. Reemerging interest in Rap1 envisages capturing its Ras suppression

  • Cancer Immunotherapy with CDK7 Inhibitors.
    Trends Cancer (IF 11.093) Pub Date : 2020-02-28
    Giulia Petroni,Lorenzo Galluzzi

    Recent findings demonstrate that pharmacological cyclin-dependent kinase 7 (CDK7) inhibitors can evoke anticancer immunity upon genomic destabilization of neoplastic cells. Besides adding CDK7 to the expanding list of cell cycle proteins that impinge on immune regulation, these results support the value of aggravating genomic instability in cancer cells to enable immunological disease control.
