BACKGROUND: Hepatocellular carcinoma (HCC) causes over 800,000 deaths worldwide annually, mainly in low income countries, and incidence is rising rapidly in the developed world with the spread of hepatitis B (HBV) and C (HCV) viruses. Natural Killer (NK) cells protect against viral infections and tumours by killing abnormal cells recognised by Killer-cell Immunoglobulin-like Receptors (KIR). Thus genes and haplotypes encoding these receptors may be important in determining both outcome of initial hepatitis infection and subsequent chronic liver disease and tumour formation...

Autologous, patient-specific chimeric antigen receptor T-cell (CART) therapy has emerged as a powerful and potentially curative therapy for cancer, especially for CD19-positive hematological malignancies. Indeed, on August 30, 2017, the University of Pennsylvania-designed CD19-directed CART (CART-19) cell therapy (CTL019, tisagenlecleucel-t, Kymriah - Novartis) became the first CART therapy approved by the Food and Drug Administration (FDA) for acute lymphoblastic leukemia. However, the development of CART technology and its wider application is partly limited by the patient-specific nature of such a platform and by the time required for manufacturing...

Initial research on vitamin E and cancer has focused on α-tocopherol (αT), but recent clinical studies on cancer-preventive effects of αT supplementation have shown disappointing results, which has led to doubts about the role of vitamin E, including different vitamin E forms, in cancer prevention. However, accumulating mechanistic and preclinical animal studies show that other forms of vitamin E, such as γ-tocopherol (γT), δ-tocopherol (δT), γ-tocotrienol (γTE), and δ-tocotrienol (δTE), have far superior cancer-preventive activities than does αT...

Despite tremendous research efforts for effective therapies, cancer remains the plague of the century and its burden is expected to increase worldwide in the near future. Metabolic reprogramming is a firmly established hallmark of all cancers, regardless their cellular or tissue origin, being a prerequisite for both tumor growth and invasion. Functional dependence of tumors on glycolysis and glutaminolysis and the crucial contribution of mitochondria to the tumor bioenergetic versatility are well recognized features and established therapeutic targets...

Background: Integrative oncology, which is generally understood to refer to the use of a combination of complementary medicine therapies in conjunction with conventional cancer treatments, has been defined in different ways, but there is no widely accepted definition. We sought to develop and establish a consensus for a comprehensive definition of the field of integrative oncology. Methods: We used a mixed-methods approach that included a literature analysis and a consensus procedure, including an interdisciplinary expert panel and surveys, to develop a comprehensive and acceptable definition for the term "integrative oncology...

Immune checkpoint blockade therapy using anti-PD-1 or anti-PD-L1 antibodies can unleash anti-tumor immunity and induce durable remission in a variety ofhuman cancers. However, the regulatory mechanisms of PD-L1 expression mediating immune evasion ofcancer cells have not been fully elucidated, including the genetic alterations causing PD-L1 overexpression. Recently, we have reported a novel genetic mechanism ofimmune evasion associated with structural variations(SVs)disrupting the 3'-untranslated region(UTR)ofthe PD-L1 gene in various malignancies, such as aggressive lymphomas and gastrointestinal cancers...

Lung cancer is a malignant lung tumor with various histological variants that arise from different cell types, such as bronchial epithelium, bronchioles, alveoli, or bronchial mucous glands. The clinical course and treatment efficacy of lung cancer depends on the histological variant of the tumor. Therefore, accurate identification of the histological type of cancer and respective protein biomarkers is crucial for adequate therapy. Due to the great diversity in the molecular-biological features of lung cancer histological types, detection is impossible without knowledge of the nature and origin of malignant cells, which release certain protein biomarkers into the bloodstream...

Liver cancer is a progressive, irreversible and aggressive malignant disease, which has no effective chemotherapeutic drugs. RA-XII, a natural cyclopeptide isolated from the traditional Chinese medicine Rubia yunnanensis, exerts anti-cancer and anti-inflammatory activities. This work aimed to investigate the effects of RA-XII on a hepatic tumor and its underlying mechanisms in human hepatoma HepG2 cells. The results showed that RA-XII effectively inhibited the proliferation of HepG2 cells. Consistently, RA-XII significantly induced apoptosis in HepG2 cells by decreasing the expression of caspase 3, 8, 9, and promoting the Cleavage of PARP...

Two pharmacologic approaches that are currently at the forefront of treating advanced cancer are those that center on disrupting critical growth/survival signaling pathways within tumor cells (commonly referred to as "targeted therapies") and those that center on enhancing the capacity of a patient's immune system to mount an antitumor response (immunotherapy). Maximizing responses to both of these approaches requires an understanding of the oncogenic events present in a given patient's tumor and the nature of the tumor-immune microenvironment...

Aberrant phosphoinositide 3-kinase (PI3K), mitogen-activated protein kinase (MAPK) and WNT signalling are emerging as key events in the multistep nature of prostate tumourigenesis and progression. Here, we report a compound prostate cancer murine model in which these signalling pathways cooperate to produce a more aggressive prostate cancer phenotype. Using Cre-LoxP technology and the probasin promoter, we combined the loss of Pten (Pten(fl/fl) ), to activate the PI3K signalling pathway, with either dominant stabilized β-catenin [Catnb(+/lox(ex3)) ] or activated K-RAS (K-Ras(+/V12) ) to aberrantly activate WNT and MAPK signalling, respectively...

PURPOSE: Triple-negative breast cancers (TNBC) lack expression of three common cell surface receptors, i.e., estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER2). Accordingly, TNBCs are associated with fewer treatment options and a relatively poor prognosis. Having screened a National Cancer Institute natural compound library, the purpose of this study was to investigate the bioactivity of compound C4 (Crassin) in TNBC cells. METHODS: Cell viability assays were performed in two TNBC cell lines, MDA-MB-231 and 4T1, following C4 treatment in the presence or absence of the antioxidant N-acetyl-L-cysteine (NAC)...

Natural as well as synthetic antioxidants are constantly being investigated for their efficiency in combatting the effects of oxidative stress, which appears to be the responsible cause of several diseases, which include cancer, central nervous system disorders, ischaemia-reperfusion disorders, cardiovascular conditions and diabetes. Superoxide dismutases (SODs) constitute the ubiquitous antioxidant defenses against oxidative stress that underlies numerous pathological conditions. Therefore, the development of therapeutics aimed at either delivering MnSOD more effectively to target tissues in the body in the form of MnSOD gene therapy, or the synthesis of molecules that mimic the activity of superoxide dismutase is constantly being explored...

Ursolic acid (UA), a natural triterpene acids, is a promising anti-cancer drug due to its inhibitory effect on tumor growth and metastasis. However, clinical translation of UA is limited by its poor water solubility and low bioavailability. To overcome these problems, herein an amphiphilic self-assembly nanodrug composed of UA, lactobionic acid (LA) and low-polyamidoamine (low-PAMAM) dendrimers is developed. This near-spherical nanodrug with a uniform size (~180nm) demonstrated to have an enhanced cytotoxicity against liver cancer SMMC7721 cells, and could attenuate the migration and adhesion of SMMC7721 cells at non-toxic concentrations by suppressing metastasis-related protein MMP-9 expression...

Chimeric antigen receptor-modulated T lymphocytes (CAR-T) have emerged as a powerful tool for arousing anticancer immunity. Endogenous ligands for tumor antigen may outperform single-chain variable fragments to serve as a component of CARs with high cancer recognition efficacy and minimized immunogenicity. As heterodimerization and signaling partners for human epidermal growth factor receptor 2 (HER2), HER3/HER4 has been implicated in tumorigenic signaling and therapeutic resistance of breast cancer. In this study, we engineered T cells with a CAR consisting of the extracellular domain of heregulin-1β (HRG1β) that is a natural ligand for HER3/HER4, and evaluated the specific cytotoxicity of these CAR-T cells in cultured HER3 positive breast cancer cells and xenograft tumors...

Photodynamic therapy (PDT) has received high attention in cancer treatment due to its minimal side effects, specific cancer-targeting, non-invasion and low cost. It utilizes a specific group of anti-cancer drugs called photosensitizers (PS), which can be only activated under a certain wavelength light illumination and kills cancer cells. To screen the potential of PS and setup of PDT treatment protocol, it is essential to assess the PDT efficacy in vitro. In this study, a light-emitting diode- (LED-) based illumination system at two wavelengths (red & blue) with homogeneous and stable irradiation, and constant temperature conditions in 96-well plates was provided...

Human epidermal growth factor receptor 2 (HER2) is a tumor associated antigen over-expressed in 20-30% of cases of breast cancer. Passive immune therapy with HER2-directed monoclonal antibodies (mabs) has changed the natural history of this subset of breast tumors both in the localized and metastatic settings. The safety and efficacy of HER2 vaccines have been assessed in early phase clinical trials but to date clinically relevant results in late phase trials remain an elusive target. Here, we review the recent translational discoveries related to the interactions between the adaptive immune system and the HER2 antigen in breast cancer, results of published clinical trials, and future directions in the field of HER2 vaccine treatment development...
