Pediatric cancers are rare malignancies worldwide and represent around 1% of all new cancer diagnoses [...]
Inhibition of colon cancer growth by docosahexaenoic acid involves autocrine production of TNFα
2016
IF 7.932; International audience; The omega-3 polyunsaturated fatty acid docosahexaenoic acid (DHA) has anti-inflammatory and anti-cancer properties. Among pro-inflammatory mediators, tumor necrosis factor a (TNF alpha) plays a paradoxical role in cancer biology with induction of cancer cell death or survival depending on the cellular context. The objective of the study was to evaluate the role of TNFa in DHA-mediated tumor growth inhibition and colon cancer cell death. The treatment of human colorectal cancer cells, HCT-116 and HCT-8 cells, with DHA triggered apoptosis in autocrine TNF alpha-dependent manner. We demonstrated that DHA-induced increased content of TNF alpha mRNA occurred thr…
Relevance of the natural HDAC inhibitor sulforaphane as a chemopreventive agent in urologic tumors.
2018
Due to an increased understanding of molecular biology and the genomics of cancer, new and potent agents have been approved by the Food and Drug Administration (FDA) to fight this disease. However, all of these drugs cause severe side effects and resistance inevitably develops, re-activating tumor growth and dissemination. For this reason, patients turn to natural compounds as alternative or complementary treatment options, since it has been found that natural plant products may block, inhibit, or reverse cancer development. The present review focusses on the role of the natural compound sulforaphane (SFN) as an anti-tumor agent in urologic cancer. SFN is a natural compound found in crucife…
The importance of transmembrane domain interactions in the viral control of apoptosis
2021
Viral control of apoptosis occurs through the expression of viral encoded anti-apoptotic B-cell lymphoma 2 (BCL2) analogs. These proteins are thought to restrain apoptosis by interacting with cellular BCL2 family members. We identified that protein-protein interactions between cellular and viral BCL2 transmembrane domains are crucial for the viral protein’s function.

Hypoxia-Inducible Factor-1α Activity as a Switch for Glioblastoma Responsiveness to Temozolomide
2018
Rationale: The activity of the transcription factor, hypoxia-inducible factor (HIF)-1?, is a common driver of a number of the pathways involved in the aggressiveness of glioblastomas (GBMs), and it has been suggested that the reduction in this activity observed, soon after the administration of temozolomide (TMZ), can be a biomarker of an early response in GBM models. As HIF-1? is a tightly regulated protein, studying the processes involved in its downregulation could shed new light on the mechanisms underlying GBM sensitivity or resistance to TMZ. Methods: The effect of HIF-1? silencing on cell responsiveness to TMZ was assessed in four genetically different human GBM cell lines by evaluat…
Targeting Immune Modulators in Glioma While Avoiding Autoimmune Conditions
2021
Simple Summary Glioblastoma multiforme is a futile disease usually leading to the patient’s death within one year post-diagnosis; therefore, novel treatment options are desperately needed. In this regard, activation of the inert immune system has moved into focus in recent years. Malignant brain tumors, as well as autoimmune diseases, elicit aberrant immune responses. In this way, glioma escapes the host’s immune system and, thus, activation of the immune response in order to reduce tumor tolerance can serve as an alternative treatment option. Immune checkpoint modulators in combination with traditional therapies have gained attention in both glioma and autoimmune diseases. In this review, …
Hormone Involvement in Tissue Development, Physiology and Oncogenesis: A Preface to the Special Issue
2020
Hormones, i.e., the products of specialized endocrine cells which spread throughout the body via the bloodstream, control the normal development and growth of organisms at the embryo-fetal stage and, in adult life, regulate, integrate, and coordinate a range of different physiological processes which concern virtually all body tissues. They exert their biological effects by interacting with either surface or intracellular receptors, thereby activating signalization pathways [1]. For example, steroid hormones, such as those released by the adrenal glands, testes and ovaries, once freely crossed through the plasmalemma, bind to receptors that act as ligand-dependent transcriptional regulators…

Cadmium-Associated Molecular Signatures in Cancer Cell Models
2021
Simple Summary The exposure of cancer cells to cadmium compounds may be associated with the acceleration of tumor progression. It is known that cadmium is a transcriptional regulator, and the study of differentially expressed genes has enabled the identification and classification of cadmium-associated molecular signatures as useful biomarkers that are potentially transferable to clinical research. This review recapitulates the studies that report the detection of such signatures in breast, gastric, colon, liver, lung, and nasopharyngeal tumor cell models, as specifically demonstrated by individual gene or whole genome expression profiling. Abstract The exposure of cancer cells to cadmium a…
