Targeting cancer stem cells improves treatment effectiveness and prevents metastasis

This study shows that for the first time, targeting the proliferating tumor mass and dormant cancer stem cells with combination therapy effectively inhibited tumor growth and prevented metastasis compared to monotherapy in mice,” said Wang, who is a member of the UCLA Jonsson Comprehensive Canc er Center and of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA. “Our discovery could be applied to other solid tumors such as breast and colon cancer, which also frequently metastasizes to lymph nodes or distant organs.”“With this new and exciting study, Dr. Wang and his team have provided the building blocks for understanding the cellular and genetic mechanisms behind squamous cell carcinoma,” said Dr. Paul Krebsbach, dean of the UCLA School of Dentistry. “The work has important translational values. Small m olecule inhibitors for cancer stem cells in this study are available or being utilized in clinical trials for other diseases. It will be interesting to conduct a clinical trial to test these inhibitors for head and neck squamous cell carcinoma.”Additional authors of the study include Demeng Cheng, first author and postdoctoral scholar in Wang ’s lab; Mansi Wu, Yang Li, Dr. Insoon Chang, Yuan Quan, Mari Salvo, Peng Deng, Dr. Bo Yu, Yongxin Yu, Jiaqiang Dong, John M. Szymanski, Sivakumar Ramadoss and Jiong Li who are all from the laboratory of molecular signaling in the division of oral biology...

Authors: Lee HJ, Han YM, An JM, Kang EA, Park YJ, Cha JY, Hahm KB Abstract INTRODUCTION: Although inflammation is defensive and healing process that maintains organ homeostasis, unresolved inflammation can lead to diseases. Polyunsaturated fatty acids (PUFAs), especially n-6 PUFAs abundant in Western diet, are precursors of pro-inflammatory mediators, whereas n-3 PUFAs possess anti-inflammatory properties. Therefore, interest in the cancer-preventive effect of n-3 PUFAs is increasing. Areas covered: We have observed significant reductions of gastrointestinal (GI) tumorigenesis in the Fat-1 transgenic mouse as evide...

Authors: Spallanzani A, Orsi G, Andrikou K, Gelsomino F, Rimini M, Riggi L, Cascinu S Abstract INTRODUCTION: Since 2007 Sorafenib has represented the only approved drug for first-line treatment of advanced hepatocellular carcinoma (HCC). Lenvatinib, an orally active inhibitor of multiple receptor tyrosine kinases (VEGFR 1-3, FGFR 1-4, PDGFRa, RET and KIT), showed preclinical and clinical activity in the treatment of solid tumours, including HCC. Areas covered: In this review we summarize the current therapeutic paradigm for the systemic treatment of advanced HCC, focusing on Lenvatinib pre-clinical and clinical dev...

Authors: Jones RL, Le Cesne A, Ibrahim T, Garcia Del Muro X, Menge F Abstract INTRODUCTION: Health-related quality of life (HRQoL) is a patient-reported outcome that addresses patients' perceptions of symptoms across physical, emotional, cognitive and social domains. As HRQoL is currently rarely measured outside clinical trials in oncology, it must be inferred from patients' everyday performance during treatment. To gain insight into the HRQoL of advanced STS patients receiving palliative treatment in clinical practice, three case studies of patients treated with trabectedin are examined. Areas covered: The patient...

was established in 2004 and consents patients in Wales, UK with a known or suspected cancer diagnosis to donate biosamples for future research. The resource is open access to all researchers working in cancer research, regardless of geographic location or employment sector. To December 2017, just over 13,500 patients have donated samples across a variety of tumour types. Tumour and adjacent normal tissue and blood samples are routinely collected, stored and processed to standardised protocols. Bespoke collections for unique samples such as urine or ascites are also available. Pathology data, clinical data including treatm...

Publication date: Available online 17 September 2018Source: Journal of Molecular Graphics and ModellingAuthor(s): Ria Biswas, Nilkanta Chowdhury, Ranjita Mukherjee, Angshuman BagchiAbstractThe interaction of the proteins, tumor necrosis factor receptor-associated factor6 (TRAF6) and Basigin (CD147), is known to be associated with the over-expression of matrix metalloproteinases (MMPs) in melanoma cells. MMPs are known to be responsible for melanoma metastasis. Hence, TRAF6-Basigin complex can act as a potential therapeutic target. In previous studies, amino acid residues Lys340, Lys 384, Glu417 and Glu511 of TRAF6 were ide...

The introduction of aggressive chemotherapy with allogeneic stem cell transplantation has resulted in improved clinical outcomes in younger patients. However, the treatment results in unfit elderly AML population remain disappointing. New strategies should be introduced to improve the prognosis in this group of patients. Areas covered: This review presents and discusses the mechanism of action, safety and efficacy of sapacitabine in AML patients. Expert opinion: Sapacit...

Authors: Campione E, Ventura A, Diluvio L, Mazzeo M, Mazzilli S, Garofalo V, Di Prete M, Bianchi L Abstract INTRODUCTION: Actinic keratosis (AK) is considered as a superficial squamous cell carcinoma (SCC). A central role in the pathogenesis is played by chronic sun exposure. UVB causes direct damage to DNA, producing pyrimidine dimers, and suppressing the protective role of p53. The stepwise progression of AK, with an increased expression of anti-apoptotic Bcl-2, favors the progression to SCC. Moreover, the dermal response characterized by inflammation and mediated by prostaglandins is a critical component of tumo...

Glutathione transferases (GSTs) as an extensive expressed metabolic enzyme in human, plays a significant role in the metabolism of cisplatin. Thus, sensitively and accura...
