Driver mutations and differential sensitivity to targeted therapies: a new approach to the treatment of lung adenocarcinoma
2010
The adenocarcinoma of the lung has recently shown peculiar molecular characteristics, which relate with both carcinogenesis and response to targeted drugs. Several molecular alterations have been defined as "driver mutations". These are responsible for both the initiation and maintenance of the malignancy. The epidermal growth factor receptor (EGFR) pathway is the main regulator of cell function and cancer development. It has a widely defined role in the occurrence of driver mutations. Up till now EGFR gene mutations, KRAS gene mutations and EML4-ALK fusion genes are the most widely recognized alterations involved in both the biology and the clinical management of lung adenocarcinoma. In th…
Signal transduction pathways of the epidermal growth factor receptor in colorectal cancer and their inhibition by small molecules.
2012
While prognostic factors can help to classify the standard risk of subpopulations of patients with the same tumor entity, it is still not possible to predict the response of individual patients to specific therapies. The reason for such wide variation in cancer therapy responses remains largely unknown. The field of chemotherapy is currently undergoing a paradigm shift from classical cytotoxic chemotherapy to targeted therapy in order to kill tumor cells more efficiently with fewer side effects on normal tissue. In the present review, we focus on colorectal carcinoma, which is one of the most frequent tumor types worldwide and represents a leading cause of cancer-related deaths. The signali…
Bispecific T-Cell Engager (BiTE) Antibody Construct Blinatumomab for the Treatment of Patients With Relapsed/Refractory Non-Hodgkin Lymphoma : Final …
2016
Purpose Blinatumomab is a CD19/CD3 BiTE (bispecific T-cell engager) antibody construct for the treatment of Philadelphia chromosome–negative acute B-lymphoblastic leukemia. We evaluated blinatumomab in relapsed/refractory B-cell non-Hodgkin lymphoma (NHL). Patients and Methods This 3 + 3 design, phase I dose-escalation study determined adverse events and the maximum tolerated dose (MTD) of continuous intravenous infusion blinatumomab in patients with relapsed/refractory NHL. Blinatumomab was administered over 4 or 8 weeks at seven different dose levels (0.5 to 90 μg/m2/day). End points were incidence of adverse events, pharmacokinetics, pharmacodynamics, and overall response rate. Results B…
Follistatin as potential therapeutic target in prostate cancer
2012
Follistatin is a single-chain glycosylated protein whose primary function consists in binding and neutralizing some members of the transforming growth factor-β superfamily such as activin and bone morphogenic proteins. Emerging evidence indicates that this molecule may also play a role in the malignant progression of several human tumors including prostate cancer. In particular, recent findings suggest that, in this tumor, follistatin may also contribute to the formation of bone metastasis through multiple mechanisms, some of which are not related to its specific activin or bone morphogenic proteins' inhibitory activity. This review provides insight into the most recent advances in understa…
Improvement in survival of metastatic colorectal cancer: Are the benefits of clinical trials reproduced in population-based studies?
2012
To describe trends in survival of non-resectable metastatic colorectal cancer (MCRC) over a 34-year period in a French population-based registry taking into account major advances in medical therapy.3804 patients with non-resectable metastatic colorectal cancer diagnosed between 1976 and 2009 were included. Three periods (1976-96, 1997-2004 and 2005-09) were considered.The proportion of patients receiving chemotherapy dramatically increased from 19% to 57% between the first two periods, then increased steadily thereafter reaching 59% during the last period (p0.001). Median relative survival increased from 5.9 months during the 1976-96 period to 10.2 months during the 1997-2004 period but, d…
MUC1 intracellular bioactivation mediates lung fibrosis
2019
BackgroundSerum KL6/mucin 1 (MUC1) has been identified as a potential biomarker in idiopathic pulmonary fibrosis (IPF), but the role of MUC1 intracellular bioactivation in IPF is unknown.ObjectiveTo characterise MUC1 intracellular bioactivation in IPF.Methods and resultsThe expression and phosphorylation of Thr41 and Tyr46 on the intracellular MUC1-cytoplasmic tail (CT) was increased in patients with IPF (n=22) compared with healthy subjects (n=21) and localised to fibroblasts and hyperplastic alveolar type II cells. Transforming growth factor (TGF)-β1 phosphorylated SMAD3 and thereby increased the phosphorylation of MUC1-CT Thr41 and Tyr46 in lung fibroblasts and alveolar type II cells, ac…
Glucagon-like peptide-2 and mouse intestinal adaptation to a high-fat diet.
2013
Endogenous glucagon-like peptide-2 (GLP2) is a key mediator of refeeding-induced and resection-induced intestinal adaptive growth. This study investigated the potential role of GLP2 in mediating the mucosal responses to a chronic high-fat diet (HFD). In this view, the murine small intestine adaptive response to a HFD was analyzed and a possible involvement of endogenous GLP2 was verified using GLP2 (3–33) as GLP2 receptor (GLP2R) antagonist. In comparison with animals fed a standard diet, mice fed a HFD for 14 weeks exhibited an increase in crypt–villus mean height (duodenum, 27.5±3.0%; jejunum, 36.5±2.9%;P<0.01), in the cell number per villus (duodenum, 28.4±2.2%; jejunum, 32.0±2.9%;P&l…
Nanocapsules with specific targeting and release properties using miniemulsion polymerization.
2013
The field of application for nanosized materials ranges from mere technical purposes to a growing field of applications in biomedicine. Among the different techniques and processes to produce these materials for encapsulation of reporter molecules and drugs, the miniemulsion process has been proven to be highly adaptable to these specific needs.The review covers the recent developments in the field of miniemulsion as a very powerful technique for the formation of complex carriers for the encapsulation of different kinds of reporter molecule and drugs. The use of a wide variety of polymerization techniques in the miniemulsion process and possible utilization of a wide range of monomers as re…
