    The role of autophagy in hepatocellular carcinoma: friend or foe.
    Oncotarget 2017 Aug 18;8(34):57707-57722. Epub 2017 Apr 18.
    Institute of Liver Diseases, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China.
    Autophagy is an evolutionarily conserved lysosome-dependent catabolic process which degrades cell's components in order to recycle substrates to exert optimally and adapt to tough circumstances. It is a critical cellular homeostatic mechanism with stress resistance, immunity, antiaging, and pro-tumor or anti-tumor effects. Among these, the role of autophagy in cancer is the most eye-catching that is not immutable but dynamic and highly complex. Read More

    Anaplastic Lymphoma Kinase in Cutaneous Malignancies.
    Cancers (Basel) 2017 Sep 12;9(9). Epub 2017 Sep 12.
    Harvard Medical School, Boston, MA 02115, USA.
    Anaplastic lymphoma kinase (ALK) is a receptor tyrosine kinase that has been implicated in the pathogenesis of a variety of neoplasms. As suggested by its name, ALK was first described as part of a translocation product in cases of anaplastic large-cell lymphoma, with other genetic and cytogenetic ALK mutations subsequently coming to attention in the development of many other hematologic and solid organ malignancies. ALK has now been shown to play a role in the pathogenesis of several cutaneous malignancies, including secondary cutaneous systemic anaplastic large-cell lymphoma (ALCL) and primary cutaneous ALCL, melanoma, spitzoid tumors, epithelioid fibrous histiocytoma, Merkel cell carcinoma, and basal cell carcinoma.

    Urothelial Carcinoma Stem Cells: Current Concepts, Controversies, and Methods.
    Methods Mol Biol 2018 ;1655:121-136
    Solid Tumour Target Discovery Laboratory, Newcastle Cancer Centre, Northern Institute for Cancer Research, Medical School, Newcastle University, Newcastle Upon Tyne, NE2 4HH, UK.
    Cancer stem cells are defined as a self-renewing and self-protecting subpopulation of cancer cells able to differentiate into morphologically and functionally diverse cancer cells with a limited lifespan. To purify cancer stem cells, two basic approaches can be applied, the marker-based approach employing various more of less-specific cell surface marker molecules and a marker-free approach largely based on various self-protection mechanisms. Within the context of urothelial carcinoma, both methods could find use. Read More

    Molecular Subtype Profiling of Urothelial Carcinoma Using a Subtype-Specific Immunohistochemistry Panel.
    Methods Mol Biol 2018 ;1655:53-64
    Division of Urological Research, Department of Translational Medicine, Lund University, Box 117, SE-221 00, Lund, Sweden.
    Molecular subtypes of bladder cancer (BC) can be determined by relatively small immunohistochemistry panels both for non-muscle invasive (NMI) and muscle invasive (MI) tumors. For analysis of NMI tumors, as few as two markers are needed, although classification is dependent also on pathological grade and histological evaluation. The result is a classification into the three tumor-cell phenotypes of NMI-BC, Urothelial-like (Uro), Genomically Unstable (GU), and Basal/SCC-like. Read More

    Small Molecule Inhibitors of the Hedgehog Pathway in the Treatment of Basal Cell Carcinoma of the Skin.
    Am J Clin Dermatol 2017 Sep 8. Epub 2017 Sep 8.
    Department of Dermatology, University of Colorado School of Medicine, Mail Stop F703, 1665, North Aurora Court, Aurora, CO, 80045, USA.
    Basal cell carcinoma (BCC) is the most common type of skin cancer, with rising incidence rates primarily attributed to an aging population and ultraviolet radiation exposure. While the majority of BCCs are localized and respond to standard therapies, a very small minority of these tumors become locally destructive or metastasize. These advanced BCCs may not be amenable to localized treatment with surgery and/or radiation therapy. Read More

    Transcription factors NRF2 and HSF1 have opposing functions in autophagy.
    Sci Rep 2017 Sep 8;7(1):11023. Epub 2017 Sep 8.
    Jacqui Wood Cancer Centre, Division of Cancer Research, School of Medicine, University of Dundee, Dundee, DD1 9SY, Scotland, UK.
    Autophagy plays a critical role in the maintenance of cellular homeostasis by degrading proteins, lipids and organelles. Autophagy is activated in response to stress, but its regulation in the context of other stress response pathways, such as those mediated by heat shock factor 1 (HSF1) and nuclear factor-erythroid 2 p45-related factor 2 (NRF2), is not well understood. We found that the Michael acceptor bis(2-hydoxybenzylidene)acetone (HBB2), a dual activator of NRF2 and HSF1, protects against the development of UV irradiation-mediated cutaneous squamous cell carcinoma in mice.

    Lasers and intense pulsed light (IPL) association with cancerous lesions.
    Lasers Med Sci 2017 Sep 7. Epub 2017 Sep 7.
    University of Wales Trinity Saint David, Swansea, SA1 6ED, UK.
    The development and use of light and lasers for medical and cosmetic procedures has increased exponentially over the past decade. This review article focuses on the incidence of reported cases of skin cancer post laser or IPL treatment. The existing evidence base of over 25 years of laser and IPL use to date has not raised any concerns regarding its long-term safety with only a few anecdotal cases of melanoma post treatment over two decades of use; therefore, there is no evidence to suggest that there is a credible cancer risk.

    Mutations in ACTRT1 and its enhancer RNA elements lead to aberrant activation of Hedgehog signaling in inherited and sporadic basal cell carcinomas.
    Nat Med 2017 Sep 4. Epub 2017 Sep 4.
    Paris Descartes University, Sorbonne Paris Cité, Paris, France.
    Basal cell carcinoma (BCC), the most common human cancer, results from aberrant activation of the Hedgehog signaling pathway. Although most cases of BCC are sporadic, some forms are inherited, such as Bazex-Dupré-Christol syndrome (BDCS)-a cancer-prone genodermatosis with an X-linked, dominant inheritance pattern. We have identified mutations in the ACTRT1 gene, which encodes actin-related protein T1 (ARP-T1), in two of the six families with BDCS that were examined in this study. Read More

    Molecular Variations in Histologic Subtypes of Basal Cell Carcinoma.
    Skinmed 2017 1;15(4):265-268. Epub 2017 Aug 1.
    Section of Dermatology, The University of Chicago Pritzker School of Medicine, Chicago, IL;
    There are many molecular variations in the histologic subtypes of basal cell carcinoma (BCC); Ki67 and Bcl-2 expression differs among them and might relate to their prognostic features. The clinically notable friability and its histologic counterpart, retraction, are dependent on cell-cell adhesion and basement membrane characteristics, which may be altered in different ways depending on the tumor morphology and phenotype. Finally, we discuss the pathogenesis of BCCs and recent molecular advances with a review of new and upcoming molecular-based therapeutics. Read More
