    Long-Lived Epidermal Cancer-Initiating Cells.
    Int J Mol Sci 2017 Jun 27;18(7). Epub 2017 Jun 27.
    Department of Medicine, Monash University Central Clinical School, Prahran, VIC 3004, Australia.
    Non-melanomatous skin cancers (NMSCs), which include basal and squamous cell carcinoma (BCC and SCC respectively), represent a significant burden on the population, as well as an economic load to the health care system; yet treatments of these preventable cancers remain ineffective. Studies estimate that there has been a 2-fold increase in the incidence of NMSCs between the 1960s and 1980s. The increase in cases of NMSCs, as well as the lack of effective treatments, makes the need for novel therapeutic approaches all the more necessary. Read More

    HIF-2α not HIF-1α overexpression confers poor prognosis in non-small cell lung cancer.

    Sirtuin 6 plays an oncogenic role and induces cell autophagy in esophageal cancer cells.
    Tumour Biol 2017 Jun;39(6):1010428317708532
    1 Department of Clinical Laboratory Medicine, Shanghai Tenth People's Hospital of Tongji University, Shanghai, China.
    Sirtuin 6, a member of sirtuin family, is generally regarded as a tumor suppressor as it participates in suppressing hypoxia-inducible factor 1α and MYC transcription activity by deacetylating H3K9 (histone H3 lysine 9) and H3K56 (histone H3 lysine) at promoters of target genes, leading to the aerobic glycolysis inhibition and cell growth suppression. However, its expression has recently been reported to be highly elevated in a series of tumors, including prostate cancer, breast cancer, and non-small cell lung cancer, indicating that sirtuin 6 plays dual roles in tumorigenicity in a cell/tumor type-specific manner. To our knowledge, the biological roles of sirtuin 6 in esophageal cancer cells have still been underestimated. Read More

    Angiotensin 1-7 inhibits angiotensin II-stimulated head and neck cancer progression.
    Eur J Oral Sci 2017 Jun 27. Epub 2017 Jun 27.
    Academic Unit of Oral and Maxillofacial Pathology, School of Clinical Dentistry, University of Sheffield, Sheffield, UK.
    Angiotensin II (Ang II) is the product of the proteolytic action of angiotensin-converting enzyme (ACE) on the precursor peptide, angiotensin I (Ang I). In addition to its vasoactive properties, Ang II is able to stimulate angiogenesis and act as a mitogen, promoting cellular proliferation. Recently, evidence has emerged that Ang II is also able to promote tumour invasion, a key step in the metastatic cascade, although the mechanisms by which it does so remain largely obscure.

    Fluorescent Nanoparticle Imaging Allows Noninvasive Evaluation of Immune Cell Modulation in Esophageal Dysplasia.
    Mol Imaging 2014 May;13(3):7290201400003
    From the Division of Nuclear Medicine and Molecular Imaging, Department of Radiology, Massachusetts General Hospital, Boston, MA; Division of Gastroenterology, Departments of Medicine and Genetics, Abramson Cancer Center, University of Pennsylvania, Philadelphia, PA; and Division of Digestive and Liver Diseases, Department of Medicine, and Herbert Irving Comprehensive Cancer Center, Columbia University Medical Center, New York, NY.
    Esophageal tumors provide unique challenges and opportunities for developing and testing surveillance imaging technology for different tumor microenvironment components, including assessment of immune cell modulation, with the ultimate goal of promoting early detection and response evaluation. In this context, accessibility through the lumen using a minimally invasive approach provides a means for repetitive evaluation longitudinally by combining fluorescent endoscopic imaging technology with novel fluorescent nanoparticles that are phagocytized by immune cells in the microenvironment. The agent we developed for imaging is synthesized from Feraheme (ferumoxytol), a Food and Drug Administration-approved monocrystaline dextran-coated iron oxide nanoparticle, which we conjugated to a near-infrared fluorochrome, CyAL5.

    Carcinogenesis 2017 Jun 22. Epub 2017 Jun 22.
    International Agency for Research on Cancer (IARC-WHO), Lyon, France.
    Alcohol is a major risk factor for oesophageal squamous cell carcinoma (OSCC), the most prevalent histological subtype of oesophageal cancer (OC) worldwide. The metabolism of alcohol is regulated by specific enzymes whose activity and expression is influenced by genetic polymorphisms. We conducted a systematic review of current epidemiological evidence of the relationship between alcohol intake and OC risk, including the role of tobacco smoking and functional polymorphisms of dehydrogenases (ADHs) and aldehyde dehydrogenases (ALDHs).

    Biostatistical Sciences Department, Mashhad University of Medical Sciences, Mashhad, Iran.
    Squamous cell carcinoma (SCC) is the sixth most frequent malignant tumor of the head and neck region. Despite advances in therapeutic options over the last decades, the rate of mortality and morbidity has not been improved markedly. A small subset of cells, cancer stem cells (CSCs), with self-renewal properties have become a major focus of current cancer research. Read More

    Current understanding of cancer stem cells: Review of their radiobiology and role in head and neck cancers.
    Head Neck 2017 Jun 23. Epub 2017 Jun 23.
    International Centre for Allied Health Evidence and Sansom Institute for Health Research, University of South Australia, Adelaide, Australia.
    Evidence of cancer cells that bear attributes analogous to those of normal stem cells has developed a hierarchical model of cancer's architecture and progression. This subset of cancer stem cells (CSCs) drives the progression and therapy resistance of cancers. Research to identify the phenotypes of these CSCs presents evidence of a subpopulation that is more resistant to therapy and may proliferate in response. Read More

    Cytokeratin 19 expression in early oral squamous cell carcinoma and their metastasis: Inadequate biomarker for one-step nucleic acid amplification implementation in sentinel lymph node biopsy procedure.
    Head Neck 2017 Jun 23. Epub 2017 Jun 23.
    Department of Pathology, University Medical Center Utrecht, Utrecht, The Netherlands.
    Background: Intraoperative analysis of lymph nodes during a sentinel lymph node biopsy (SLNB) procedure could result in one-step surgery for early oral squamous cell carcinoma (OSCC) with an occult nodal metastasis. One-step nucleic acid amplification rapidly detects cytokeratin 19 (CK19) RNA with high accuracy. Sensitivity and specificity of CK19 expression in OSCC was evaluated. Read More

    Effect of TET1 regulating MGMT on chemotherapy resistance of oral squamous cell carcinoma stem cells.
