    Abstract In recent decades cancer emerged as one of the leading causes of death in the developed countries, with some types of cancer contributing to the top 10 causes of death on the list of the World Health Organization. Carcinogenesis, a malignant transformation causing formation of tumors in normal tissues, is associated with changes in the cell cycle caused by suppression of signaling pathways leading to cell death and facilitation of those enhancing proliferation. Further progression of cancer, during which benign tumors acquire more aggressive phenotypes, is characterized by metastatic dissemination through the body driven by augmented motility and invasiveness of cancer cells. All these processes are associated with alterations in calcium homeostasis in cancer cells, which promote their proliferation, motility and invasion, and dissuade cell death or cell cycle arrest. Remodeling of store-operated calcium entry (SOCE), one of the major pathways regulating intracellular Ca

    Abstract The TRPV6 calcium channel is known to be up-regulated in various tumors. The efforts to target the TRPV6 channel in vivo are still ongoing to propose an effective therapy against cancer. Here, we report the generation of two antibodies raised against extracellular epitopes corresponding to the extracellular loop between S1 and S2 (rb79) and the pore region (rb82). These antibodies generated a complex biphasic response with the transient activation of the TRPV6 channel. Store-operated calcium entry was consequently potentiated in the prostate cancer cell line LNCaP upon the treatment. Both rb79 and rb82 antibodies significantly decreased cell survival rate in a dose-dependent manner as compared to the control antibodies of the same isotype. This decrease was due to the enhanced cell death via apoptosis revealed using a sub-G1 peak in a cell cycle assay, TUNEL assay, and a Hoechst staining, having no effects in the PC3M

    Abstract Store-operated calcium entry (SOCE) plays important roles in a multitude of cellular processes, from muscle contraction to cellular proliferation and migration. Dysregulation of SOCE is responsible for the advancement of multiple diseases, ranging from immune diseases, myopathies, to terminal ones like cancer. Naturally, SOCE has been a focus of many studies and review papers which, however, primarily concentrated on the principal players localized to the plasma membrane and responsible for Ca

    Abstract Transient receptor potential (TRP) channels are recently identified proteins that form a versatile family of ion channels, the majority of which are calcium permeable and exhibit complex regulatory patterns with sensitivity to multiple environmental factors. While this sensitivity has captured early attention, leading to recognition of TRP channels as environmental and chemical sensors, many later studies concentrated on the regulation of intracellular calcium by TRP channels. Due to mutations, dysregulation of ion channel gating or expression levels, normal spatiotemporal patterns of local Ca(2+) distribution become distorted. This causes deregulation of downstream effectors sensitive to changes in Ca(2+) homeostasis that, in turn, promotes pathophysiological cancer hallmarks, such as enhanced survival, proliferation and invasion. These observations give rise to the appreciation of the important contributions that TRP channels make to many cellular processes controlling cell fate and positioning these channels as important players in cancer regulation. This review discusses the accumulated scientific knowledge focused on TRP channel involvement in regulation of cell fate in various transformed tissues.

    Abstract Nonsense mutations are responsible for around 10% of cases of genetic diseases, including cystic fibrosis. 2,6-diaminopurine (DAP) has recently been shown to promote efficient readthrough of UGA premature stop codons. In this study, we show that DAP can correct a nonsense mutation in the Cftr gene in vivo in a new CF mouse model, in utero, and through breastfeeding, thanks, notably, to adequate pharmacokinetic properties. DAP turns out to be very stable in plasma and is distributed throughout the body. The ability of DAP to correct various endogenous UGA nonsense mutations in the CFTR gene and to restore its function in mice, in organoids derived from murine or patient cells, and in cells from patients with cystic fibrosis reveals the potential of such readthrough-stimulating molecules in developing a therapeutic approach. The fact that correction by DAP of certain nonsense mutations reaches a clinically relevant level, as judged from previous studies, makes the use of this compound all the more attractive.

    Abstract Calcium channels significantly contribute to many cellular processes, including such critical ones as proliferation, differentiation, and apoptosis. In prostate cancer, the influence of calcium channels has been known for over 30 years, with the first observations that calcium channel blockers affect the progression of cancer towards more aggressive phase. Later research identified additional classes of channel proteins having an important regulatory role and affecting malignant transformation. This review discusses the accumulated scientific knowledge focused on calcium channel involvement in regulation of cell fate in prostate tissues as well as recent developments in patents targeted at prostate cancer treatments and involving calcium channel modulators.

    Abstract Transient Receptor Potential (TRP) channel proteins are a diverse family of proteins that are expressed in many organisms, tissues and cell types. TRP channels respond to a variety of stimuli, including light, mechanical or chemical stimuli, temperature, pH or osmolarity. In addition, several TRP family members have been identified as downstream molecules in the G protein-coupled receptor signaling pathway. TRP proteins are involved in a variety of cell functions both in non-excitable and excitable cells due to their diverse permeability to cations and their ability to modulate intracellular Ca2+ signaling. Emerging evidence suggests that TRP channel dysfunction significantly contributes to the physiopathology of a number of diseases, including cardiovascular, neurological, metabolic or neoplastic disorders. This review focuses on the implication of TRP proteins in the pathogenesis of some of the most prevalent disorders in human. We summarize the current findings regarding the role of TRP proteins in the development of cardiovascular disease, diabetes mellitus as well as diabetic complications, and tumorigenesis and present TRP proteins as targets of potential diagnostic and therapeutic strategies.
