Abstract
Cancer and cardiovascular disease are the two most common causes of death worldwide. As the fields of cardiovascular medicine and oncology continue to expand, the area of overlap is becoming more prominent demanding dedicated attention and individualized patient care. We have come to realize that both fields are inextricably intertwined in several aspects, so much so that the mere presence of one, with its resultant downstream implications, has an impact on the other. Nonetheless, cardiovascular disease and cancer are generally approached independently. The focus that is granted to the predominant pathological entity (either cardiovascular disease or cancer), does not allow for optimal medical care for the other. As a result, ample opportunities for improvement in overall health care are being overlooked. Herein, we hope to shed light on the interconnected relationship between cardiovascular disease and cancer and uncover some of the unintentionally neglected intricacies of common cardiovascular therapeutics from an oncologic standpoint.

Abstract
Extracellular acidification of tumors is common. Through proton-sensing ion channels or proton-sensing G protein-coupled receptors (GPCRs), tumor cells sense extracellular acidification to stimulate a variety of intracellular signaling pathways including the calcium signaling, which consequently exerts global impacts on tumor cells. Proton-sensing ion channels, and proton-sensing GPCRs have natural advantages as drug targets of anticancer therapy. However, they and the calcium signaling regulated by them attracted limited attention as potential targets of anticancer drugs. In the present review, we discuss the progress in studies on proton-sensing ion channels, and proton-sensing GPCRs, especially emphasizing the effects of calcium signaling activated by them on the characteristics of tumors, including proliferation, migration, invasion, metastasis, drug resistance, angiogenesis. In addition, we review the drugs targeting proton-sensing channels or GPCRs that are currently in clinical trials, as well as the relevant potential drugs for cancer treatments, and discuss their future prospects. The present review aims to elucidate the important role of proton-sensing ion channels, GPCRs and calcium signaling regulated by them in cancer initiation and development. This review will promote the development of drugs targeting proton-sensing channels or GPCRs for cancer treatments, effectively taking their unique advantage as anti-cancer drug targets.

Abstract
INTRODUCTION The Ca2+ signaling toolkit is currently under investigation as a potential target for addressing the threat of cancer. A growing body of evidence suggests that calcium signaling plays a crucial role in promoting various aspects of cancer, including cell proliferation, progression, drug resistance, and migration-related activities. Consequently, focusing on these altered Ca2+ transporting proteins has emerged as a promising area of research for cancer treatment. AREAS COVERED This review highlights the existing research on the role of Ca2+-transporting proteins in cancer progression. It discusses the current studies evaluating Ca2+ channel/transporter/pump blockers, inhibitors, or regulators as potential anticancer drugs. Additionally, the review addresses specific gaps in our understanding of the field that may require further investigation. EXPERT OPINION Targeting specific Ca2+ signaling cascades could disrupt normal cellular activities, making cancer therapy complex and elusive. Therefore, there is a need for improvements in current Ca2+ signaling pathway focused medicines. While synthetic molecules and plant compounds show promise, they also come with certain limitations. Hence, exploring the framework of targeted drug delivery, structure-rationale-based designing, and repurposing potential drugs to target Ca2+ transporting proteins could potentially lead to a significant breakthrough in cancer treatment.

Abstract
Targeted therapy against cancer plays a key role in delivering safer and more efficient treatments. In the last decades, ion channels have been studied for their participation in oncogenic processes because their aberrant expression and/or function have been associated with different types of malignancies, including ovarian, cervical, and endometrial cancer. The altered expression or function of several ion channels have been associated with tumor aggressiveness, increased proliferation, migration, invasion, and metastasis of cancer cells and with poor prognosis in gynecological cancer patients. Most ion channels are integral membrane proteins easily accessible by drugs. Interestingly, a plethora of ion channel blockers have demonstrated anticancer activity. Consequently, some ion channels have been proposed as oncogenes, cancer, and prognostic biomarkers, as well as therapeutic targets in gynecological cancers. Here, we review the association of ion channels with the properties of cancer cells in these tumors, which makes them very promising candidates to be exploited in personalized medicine. The detailed analysis of the expression pattern and function of ion channels could help to improve the clinical outcomes in gynecological cancer patients.

Abstract
Mitochondria are regulators of key cellular processes, including energy production and redox homeostasis. Mitochondrial dysfunction is associated with various human diseases, including cancer. Importantly, both structural and functional changes can alter mitochondrial function. Morphologic and quantifiable changes in mitochondria can affect their function and contribute to disease. Structural mitochondrial changes include alterations in cristae morphology, mitochondrial DNA integrity and quantity, and dynamics, such as fission and fusion. Functional parameters related to mitochondrial biology include the production of reactive oxygen species, bioenergetic capacity, calcium retention, and membrane potential. Although these parameters can occur independently of one another, changes in mitochondrial structure and function are often interrelated. Thus, evaluating changes in both mitochondrial structure and function is crucial to understanding the molecular events involved in disease onset and progression. This review focuses on the relationship between alterations in mitochondrial structure and function and cancer, with a particular emphasis on gynecologic malignancies. Selecting methods with tractable parameters may be critical to identifying and targeting mitochondria-related therapeutic options. Methods to measure changes in mitochondrial structure and function, with the associated benefits and limitations, are summarized.

Abstract
Membrane-spanning 4-domains subfamily A 15 (MS4A15) belongs to transmembrane proteins and has been recognized as a regulator of various biological events including cell metabolism. Dysregulation of cell metabolism is a component of malignant transformation in numerous types of tumors, including ovarian cancer (OC). Nevertheless, whether MS4A15 is involved in OC progression remains obscure, as well as the underlying mechanisms. In the present study, we found that MS4A15 expression was significantly up-regulated in tumor tissues from OC patients compared with the matched normal adjacent samples. Higher MS4A15 expression predicted poorer overall survival rate in patients with OC. Our in vitro studies subsequently showed that MS4A15 knockdown markedly reduced the proliferation of OC cells, while its over-expression accelerated the proliferative capacity of OC cells through mediating the progression of G0/G1 cell cycle. Consistently, stable MS4A15 knockdown strongly inhibited the tumor growth in the established xenograft mouse models, along with evidently decreased expression of KI-67 positive staining. However, xenograft mouse models with MS4A15 over-expression exerted significantly accelerated tumor growth rates. We then found that MS4A15 reprogrammed energy metabolism to enhance OC progression. Under normal status, MS4A15 enhanced de novo lipid synthesis in OC cells. Upon glucose starvation, MS4A15 elevated oxidative phosphorylation (OXPHOS) to protect OC cells from starvation-induced cell death. Taken together, our findings demonstrated that MS4A15 may play an essential role in promoting OC growth mainly via reprogramming energy metabolism, and thus could be considered as a novel therapeutic target for OC treatment.

Abstract
OBJECTIVE Although experimental models suggest that use of beta-blockers, a common antihypertensive agent, may improve survival in ovarian cancer patients, results from clinical studies have been mixed. METHODS We evaluated the associations of pre-diagnostic (n = 950) and post-diagnostic (n = 743) use of antihypertensive medications with survival among patients with invasive, epithelial ovarian cancer in the Nurses' Health Study (NHS; 1994-2016) and NHSII (2001-2017), with follow-up until 2018 and 2019, respectively. Cox proportional hazards models were used to estimate hazard ratios (HR) for ovarian cancer mortality according to antihypertensive medication use before and after diagnosis, considering multiple drug classes (beta-blockers, calcium-channel blockers, thiazide diuretics, angiotensin-converting enzyme [ACE] inhibitors). RESULTS After adjusting for age, BMI, smoking status and tumor characteristics, pre-diagnostic use versus non-use of calcium-channel blockers was associated with higher ovarian cancer mortality (HR: 1.49; 95% CI: 1.13, 1.96), which was primarily due to polytherapy involving calcium-channel blockers (HR: 1.61; 95% CI: 1.15, 2.26). Pre-diagnostic use of beta-blockers, thiazide diuretics, or ACE inhibitors was not associated with ovarian cancer mortality. No association was observed for post-diagnostic antihypertensive medication use individually or in combination, except for lower mortality associated with polytherapy involving ACE inhibitors (HR: 0.53; 95% CI: 0.31, 0.91). CONCLUSION Overall, we did not find clear relationships between antihypertensive medication use and ovarian cancer mortality. However, given the limitation of the data, we cannot determine whether the association may differ by type of beta-blockers. The reasons underlying the observed associations with pre-diagnostic calcium-channel blocker use and post-diagnostic ACE inhibitor use require further investigation.

Abstract
The old Greek aphorism 'Panta Rhei' ('everything flows') is true for all living things in general. As a dynamic process, calcium signaling plays fundamental roles in cellular activities under both normal and pathological conditions, with recent researches uncovering its involvement in cell proliferation, migration, survival, gene expression, and more. The major question we address here is how calcium signaling affects cancer progression and whether it could be targeted to combine with classic chemotherapeutics or emerging immunotherapies to improve their efficacy.

Abstract
The divalent cation calcium (Ca2+) is considered one of the main second messengers inside cells and acts as the most prominent signal in a plethora of biological processes. Its homeostasis is guaranteed by an intricate and complex system of channels, pumps, and exchangers. In this context, by regulating cellular Ca2+ levels, mitochondria control both the uptake and release of Ca2+. Therefore, at the mitochondrial level, Ca2+ plays a dual role, participating in both vital physiological processes (ATP production and regulation of mitochondrial metabolism) and pathophysiological processes (cell death, cancer progression and metastasis). Hence, it is not surprising that alterations in mitochondrial Ca2+ (mCa2+) pathways or mutations in Ca2+ transporters affect the activities and functions of the entire cell. Indeed, it is widely recognized that dysregulation of mCa2+ signaling leads to various pathological scenarios, including cancer, neurological defects and cardiovascular diseases (CVDs). This review summarizes the current knowledge on the regulation of mCa2+ homeostasis, the related mechanisms and the significance of this regulation in physiology and human diseases. We also highlight strategies aimed at remedying mCa2+ dysregulation as promising therapeutical approaches.

Abstract
Ovarian cancer (OC) is the deadliest gynecologic cancer, due to late diagnosis, development of platinum resistance, and inadequate alternative therapy. It has been demonstrated that membrane ion channels play important roles in cancer processes, including cell proliferation, apoptosis, motility, and invasion. Here, we review the contribution of ion channels in the development and progression of OC, evaluating their potential in clinical management. Increased expression of voltage-gated and epithelial sodium channels has been detected in OC cells and tissues and shown to be involved in cancer proliferation and invasion. Potassium and calcium channels have been found to play a critical role in the control of cell cycle and in the resistance to apoptosis, promoting tumor growth and recurrence. Overexpression of chloride and transient receptor potential channels was found both in vitro and in vivo, supporting their contribution to OC. Furthermore, ion channels have been shown to influence the sensitivity of OC cells to neoplastic drugs, suggesting a critical role in chemotherapy resistance. The study of ion channels expression and function in OC can improve our understanding of pathophysiology and pave the way for identifying ion channels as potential targets for tumor diagnosis and treatment.

Altered Organelle Calcium Transport in Ovarian Physiology and Cancer. Cancers (Basel) 2020; 12:cancers12082232. [PMID: 32785177 PMCID: PMC7464720 DOI: 10.3390/cancers12082232] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2020] [Revised: 07/31/2020] [Accepted: 08/06/2020] [Indexed: 12/14/2022] Open
Abstract
Calcium levels have a huge impact on the physiology of the female reproductive system, in particular, of the ovaries. Cytosolic calcium levels are influenced by regulatory proteins (i.e., ion channels and pumps) localized in the plasmalemma and/or in the endomembranes of membrane-bound organelles. Imbalances between plasma membrane and organelle-based mechanisms for calcium regulation in different ovarian cell subtypes are contributing to ovarian pathologies, including ovarian cancer. In this review, we focused our attention on altered calcium transport and its role as a contributor to tumor progression in ovarian cancer. The most important proteins described as contributing to ovarian cancer progression are inositol trisphosphate receptors, ryanodine receptors, transient receptor potential channels, calcium ATPases, hormone receptors, G-protein-coupled receptors, and/or mitochondrial calcium uniporters. The involvement of mitochondrial and/or endoplasmic reticulum calcium imbalance in the development of resistance to chemotherapeutic drugs in ovarian cancer is also discussed, since Ca2+ channels and/or pumps are nowadays regarded as potential therapeutic targets and are even correlated with prognosis.

Abstract
T-type calcium channels (TTCCs) are overexpressed in several cancers. In this review, we summarize the recent advances and new insights into TTCC biology, tumor progression, and prognosis biomarker and therapeutic potential in the melanoma field. We describe a novel correlation between the Cav3.1 isoform and the increased basal autophagy in BRAFV600E-mutant melanomas and after acquired resistance to BRAF inhibitors. Indeed, TTCC blockers reduce melanoma cell viability and migration/invasion in vitro and tumor growth in mice xenografts in both BRAF-inhibitor-sensitive and -resistant scenarios. These studies open a new, promising therapeutic approach for disseminated melanoma and improved treatment in BRAFi relapsed melanomas, but further validation and clinical trials are needed for it to become a real therapeutic option.

Abstract
Purpose We investigated the impact of four types of antihypertensive medications, angiotensin receptor blockers (ARBs), beta blockers (BBs; both selective and non-selective), calcium channel blockers (CCBs), and thiazide diuretics (TDs) on survival outcomes in epithelial ovarian cancer (EOC). Materials and Methods A single-institutional retrospective chart review of 878 patients with EOC was performed. Survival was compared according to use of the four antihypertensive medications during primary treatment. Propensity score matching (ratio 1:3) was performed to control possible associated covariates, such as age, International Federation of Gynecology and Obstetrics stage, residual status after primary debulking surgery, and co-morbidity. Results Among 878 patients, 56 patients (6.4%) were ARB users, 62 (7.1%) were BB users, 107 (12.2%) were CCBs users and 32 (3.6%) used TDs. Median progression-free survival (PFS) for ARB, BB, and CCB users was 37.8, 27.2, and 23.6 months compared with 33.6 months for non-users. ARB was associated with 35% decreased risk of disease progression (hazard ratio [HR], 0.65; 95% confidence interval [CI], 0.42 to 0.99; p=0.046) in multivariate analysis. After propensity score matching, median PFS for ARB users was 37.8 months and ARB use remained to be associated with lower recurrence rate in univariate (p=0.035) and multivariate analysis (HR, 0.60; 95% CI, 0.39 to 0.93; p=0.022). Conclusion In this study, ARBs use during primary treatment is associated with lower recurrence in EOC patients. However, CCBs, BBs, and TDs did not show beneficial impact.

Abstract
OBJECTIVE To examine associations between post-diagnosis use of antihypertensive (AH) medications including thiazide diuretics (TDs), angiotensin converting enzyme inhibitors (ACEIs), beta blockers (BBs) [both non-selective (NSBBs) and selective (SBBs)] and calcium channel blockers (CCBs) and ovarian cancer-specific survival. METHODS This cohort study used SEER-Medicare data on 2195 women 66+ years of age who were diagnosed with ovarian cancer during 2007-2012 and who survived for at least 12 months. Use of an AH class was defined as two or more fills during the year after diagnosis. Ovarian cancer-specific death was assessed starting one year after diagnosis and continued through the end of 2013. Associations between AH use and ovarian cancer-specific mortality were assessed using Cox proportional hazard models, comparing users of a given class of AH to non-AH users. RESULTS Overall, 718 (33%), 690 (31%), 521 (24%), 154 (7%) of women used a TD, ACEI, BB, or CCB, respectively, with some women (48%) using more than one class of drug. Ovarian cancer-specific mortality was found to be lower among women who used an ACEI (adjusted hazard ratio [aHR] 0.76, 95% confidence interval [CI] 0.63-0.92), a TD (aHR 0.82, 95%CI 0.68-0.99), or a NSBB (aHR 0.60, 95%CI 0.43-0.83), but no such association was seen in women who took a SBB or CCB. CONCLUSION We observed that women who took certain forms of an AH medication during the year following a diagnosis of ovarian cancer were thereafter at a relatively reduced risk of dying from their disease. However, the potential for residual confounding by disease severity argues for a cautious interpretation.

Abstract
Epithelial Ovarian cancer (EOC) is the deadliest gynecologic malignancy and represents the fifth leading cause of all cancer-related deaths in women. The majority of patients are diagnosed at an advanced stage of the disease that has spread beyond the ovaries to the peritoneum or to distant organs (stage FIGO III-IV) with a 5-year overall survival of about 29%. Consequently, it is necessary to understand the pathogenesis of this disease. Among the factors that contribute to cancer development, lipids and ion channels have been described to be associated to cancerous diseases particularly in breast, colorectal and prostate cancers. Here, we reviewed the literature data to determine how lipids or lipid metabolites may influence EOC risk or progression. We also highlighted the role and the expression of the calcium (Ca2+) and calcium-activated potassium (KCa) channels in EOC and how lipids might regulate them. Although lipids and some subclasses of nutritional lipids may be associated to EOC risk, lipid metabolism of LPA (lysophosphatidic acid) and AA (arachidonic acid) emerges as an important signaling network in EOC. Clinical data showed that they are found at high concentrations in EOC patients and in vitro and in vivo studies referred to them as triggers of the Ca2+entry in the cancer cells inducing their proliferation, migration or drug resistance. The cross-talk between lipid mediators and Ca2+ and/or KCa channels needs to be elucidated in EOC in order to facilitate the understanding of its outcomes and potentially suggest novel therapeutic strategies including treatment and prevention.

Abstract
Cancer is amongst the life-threatening public health issue worldwide, hence responsible for millions of death every year. It is affecting human health regardless of their gender, age, eating habits, and ecological location. Many drugs and therapies are available for its cure still the need for effective targeted drugs and therapies are of paramount importance. In the recent past, Ca2+ signalling (including channels/transporters/pumps) are being studied as a plausible target for combating the cancer menace. Many evidence has shown that the intracellular Ca2+ homeostasis is altered in cancer cells and the remodelling is linked with tumor instigation, angiogenesis, progression, and metastasis. Focusing on these altered Ca2+ signalling tool kit for cancer treatment is a cross-cutting and emerging area of research. In addition, there are numerous phytomolecules which can be exploited as a potential Ca2+ (channels/transporters/ pumps) modulators in the context of targeting Ca2+ signalling in the cancer cell. In the present review, a list of plant-based potential Ca2+ (channel/transporters/pumps) modulators has been reported which could have application in the framework of repurposing the potential drugs to target Ca2+ signalling pathways in cancer cells. This review also aims to gain attention in and support for prospective research in this field.

Abstract
T-Type calcium channels (TTCCs) are key regulators of membrane excitability, which is the reason why TTCC pharmacology is subject to intensive research in the neurological and cardiovascular fields. TTCCs also play a role in cancer physiology, and pharmacological blockers such as tetralols and dihydroquinazolines (DHQs) reduce the viability of cancer cells in vitro and slow tumor growth in murine xenografts. However, the available compounds are better suited to blocking TTCCs in excitable membranes rather than TTCCs contributing window currents at steady potentials. Consistently, tetralols and dihydroquinazolines exhibit cytostatic/cytotoxic activities at higher concentrations than those required for TTCC blockade, which may involve off-target effects. Gene silencing experiments highlight the targetability of TTCCs, but further pharmacological research is required for TTCC blockade to become a chemotherapeutic option.

Inhibition of CatSper and Hv1 Channels and NOX5 Enzyme Affect Progesterone-Induced Increase of Intracellular Calcium Concentration and ROS Generation in Human Sperm. IRANIAN JOURNAL OF MEDICAL SCIENCES 2019; 44:127-134. [PMID: 30936599 PMCID: PMC6423429] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Indexed: 11/13/2022]
Abstract
BACKGROUND Normal sperm function depends on appropriate intracellular calcium (Cai 2+) and reactive oxygen species (ROS) levels. Calcium activates NADPH oxidase-5 (NOX5) that leads to ROS generation. The calcium channel of sperm (CatSper) is activated by progesterone and intracellular alkalization. Herein, the interactive role of CatSper, Hv1 channels, and NOX5 enzyme on Cai 2+ and ROS generation in human sperm is investigated. METHODS The present laboratory in vitro study was carried out in the School of Medicine, Shiraz University of Medical Sciences (Shiraz, Iran) during 2016. Normal semen samples (n=15) were washed and diluted to 20×106 sperm/mL. The diluted samples were divided into 16 groups containing Ham's F-10 (the control group), 2 µM NNC (CatSper inhibitor), 1 mM ZnCl2 (Hv1 inhibitor), 1 µM DPI (NOX5 inhibitor), NNC+Zn, NNC+DPI, and NNC+Zn+DPI. The other 8 groups were the same as the above except that they contained 1 µM progesterone. Cell viability and Cai 2+ were analyzed by flou-3 AM probe and PI staining, respectively, using flow cytometric method. ROS generation was assessed by chemiluminescence method. Statistical analysis was performed using the one-way ANOVA followed by Tukey's test. P values <0.05 were considered statistically significant. RESULTS Progesterone increased Cai 2+ and ROS generation. The addition of NNC, Zn, or NNC+Zn significantly decreased Cai 2+ in the control and progesterone containing groups. Progesterone-induced ROS generation was decreased significantly in all groups containing NNC, Zn, or DPI and reached to the control level when DPI was added to NNC or Zn. CONCLUSION There is a functional relationship between CatSper and Hv1 channels in increasing Cai 2++. The activity of CatSper and Hv1 channels are required for progesterone-induced ROS generation by NOX5 enzyme.

Abstract
T-type Ca2+ channels (TTCC) have been identified as key regulators of cancer cell cycle and survival. In vivo studies in glioblastoma (GBM) murine xenografts have shown that drugs able to block TTCC in vitro (such as tetralol derivatives mibefradil/NNC-55-096, or different 3,4-dihydroquinazolines) slow tumor progression. However, currently available TTCC pharmacologic blockers have limited selectivity for TTCC and are unable to distinguish between TTCC isoforms. Here we analyzed the expression of TTCC transcripts in human GBM cells and show a prevalence of Cacna1g/Cav3.1 mRNAs. Infection of GBM cells with lentiviral particles carrying short hairpin RNA against Cav3.1 resulted in GBM cell death by apoptosis. We generated a murine GBM xenograft via subcutaneous injection of U87-MG GBM cells and found that tumor size was reduced when Cav3.1 expression was silenced. Furthermore, we developed an in vitro model of temozolomide-resistant GBM that showed increased expression of Cav3.1 accompanied by the activation of macroautophagy. We confirmed a positive correlation between Cav3.1 and autophagic markers in both GBM cultures and biopsies. Of note, Cav3.1 knockdown resulted in transcriptional downregulation of p62/SQSTM1 and deficient autophagy. Together, these data identify Cav3.1 channels as potential targets for slowing GBM progression and recurrence based on their role in regulating autophagy. SIGNIFICANCE: These findings identify Cav3.1 calcium channels as a molecular target to regulate autophagy and prevent progression and chemotherapeutic resistance in glioblastoma.

Abstract
Although voltage-activated Ca2+ channels are a common feature in excitable cells, their expression in cancer tissue is less understood. T-type Ca2+ channels are particularly overexpressed in various cancers. Because of their activation profile at membrane potentials close to rest and the generation of a window current, T-type Ca2+ channels may regulate a variety of Ca2+-dependent cellular processes, including cell proliferation, survival, and differentiation. The expression of T-type Ca2+ channels is of special interest as a target for therapeutic interventions.

Abstract
Background Aberrant expression of CAV3.1, one of T-type Ca2+ channels, is reported to exert important functions in pathological processes, including carcinogenesis. However, its expression pattern and function in prostate cancer (PCa) remains unclear. Materials and methods The expression pattern of CAV3.1 was analyzed in multiple ways, including online analysis in Oncomine database, experimental analyses in cell lines, and collected clinical specimens using immunohistochemistry, quantitative reverse transcription polymerase chain reaction, and Western blot. Then, CAV3.1 was downregulated in PCa cells to explore its functions. Results Upregulated CAV3.1 in PCa tissues and cells was confirmed by analyzing mRNA expression datasets from Oncomine and quantitative reverse transcription polymerase chain reaction detection, respectively. Accordingly, significantly higher CAV3.1 protein level in PCa tissues specimens than that in benign prostatic hyperplasia tissues was indicated by immunohistochemical staining. In addition, CAV3.1 upregulation was positively associated with metastasis. Depletion of CAV3.1 impaired the proliferation, migration, and invasion ability of PCa cells demonstrating by cell functional experiments, such as CCK-8, cell cycle distribution, plate clone formation, scratch wound healing, and transwell invasion assays. Mechanistically, due to constrained Akt activity, CAV3.1 knockdown resulted in decreased level of CCND1, N-cadherin, and Vimentin, and increased level of E-cadherin whose expressions could be reversed by ectopic Akt expression. Similarly, ectopic Akt expression also rescued the inhibitory effects of CAV3.1 knockdown on cell functions like proliferation and migration in PCa cells. Conclusion Upregulated CAV3.1 is positively associated with the development of PCa. CAV3.1 knockdown can inhibit PCa cell proliferation, migration, and invasion by suppressing AKT activity.

T-Type voltage gated calcium channels: a target in breast cancer? Breast Cancer Res Treat 2018; 173:11-21. [PMID: 30242580 DOI: 10.1007/s10549-018-4970-0] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2018] [Accepted: 09/15/2018] [Indexed: 12/14/2022]
Abstract
PURPOSE The purpose of this review article is to discuss the potential of T-type voltage gated calcium channels (VGCCs) as drug targets in breast cancer. Breast cancer, attributable to the different molecular subtypes, has a crucial need for therapeutic strategies to counter the mortality rate. VGCCs play an important role in regulating cytosolic free calcium levels which regulate cellular processes like tumorigenesis and cancer progression. In the last decade, T-type VGCCs have been investigated in breast cancer proliferation. Calcium channel blockers, in general, have shown an anti-proliferative and cytotoxic effects. T-type VGCC antagonists have shown growth inhibition owing to the inhibition of CaV3.2 isoform. CaV3.1 isoform has been indicated as a tumour-suppressor gene candidate and is reported to support anti-proliferative and apoptotic activity in breast cancer. The distribution of T-type VGCC isoforms in different breast cancer molecular subtypes is diverse and needs to be further investigated. The role of T-type VGCCs in breast cancer migration, metastasis and more importantly in epithelial to mesenchymal transition (EMT) is yet to be elucidated. In addition, interlaced therapy, using a combination of chemotherapy drugs and T-type VGCC blockers, presents a promising therapeutic approach for breast cancer but more validation and clinical trials are needed. Also, for investigating the potential of T-type VGCC blocker therapy, there is a need for isoform-specific agonists/antagonists to define and discover roles of T-type VGCC specific isoforms. CONCLUSION Our article provides a review of the role of T-type VGCCs in breast cancer and also discusses future of the research in this area so that it can be ascertained whether there is any potential of T-type VGCCs as drug targets in breast cancer.

Abstract
BACKGROUND T-type calcium channels (TTCCs) mediate calcium influx across the cell membrane. TTCCs regulate numerous physiological processes including cardiac pacemaking and neuronal activity. In addition, they have been implicated in the proliferation, migration and differentiation of tumour tissues. Although the signalling events downstream of TTCC-mediated calcium influx are not fully elucidated, it is clear that variations in the expression of TTCCs promote tumour formation and hinder response to treatment. METHODS We examined the expression of TTCC genes (all three subtypes; CACNA-1G, CACNA-1H and CACNA-1I) and their prognostic value in three major solid tumours (i.e. gastric, lung and ovarian cancers) via a publicly accessible database. RESULTS In gastric cancer, expression of all the CACNA genes was associated with overall survival (OS) among stage I-IV patients (all p<0.05). By combining the three potential biomarkers, a TTCC signature was developed, which retained a significant association with OS both in stage IV and stage I-III patients. In lung and ovarian cancer, association with OS was also significant when all tumour stages were considered, but was partly lost or inconclusive after splitting cases into localized and metastatic subsets. CONCLUSIONS Alterations in CACNA gene expression are linked to tumour prognosis. Gastric cancer represents the most promising setting for further evaluation.

Abstract
BACKGROUND Cutaneous malignant melanoma arises from transformed melanocytes de novo or from congenital or acquired melanocytic naevi. We have recently reported that T-type Ca2+ channels (TT-Cs) are upregulated in human melanoma and play an important role in cell proliferation. OBJECTIVES To describe for the first time in formalin-fixed paraffin-embedded tissue the immunoexpression of TT-Cs in biopsies of normal skin, acquired melanocytic naevi and melanoma, in order to evaluate their role in melanomagenesis and/or tumour progression, their utility as prognostic markers and their possible use in targeted therapies. METHODS Tissue samples from normal skin, melanocytic naevi and melanoma were subjected to immunohistochemistry for two TT-Cs (Cav3.1, Cav3.2); markers of proliferation (Ki67), the cell cycle (cyclin D1), hypoxia (Glut1), vascularization (CD31) and autophagy (LC3); BRAF V600E mutation (VE1) and phosphatase and tensin homologue (PTEN). Immunostaining was evaluated by histoscore. In silico analysis was used to assess the prognostic value of TT-C overexpression. RESULTS TT-C immunoexpression increased gradually from normal skin to common naevi, dysplastic naevi and melanoma samples, but with differences in the distribution of both isoforms. Particularly, Cav3.2 expression was significantly higher in metastatic melanoma than in primary melanoma. Statistical correlation showed a linear interaction between PTEN loss/BRAF V600E/Cav3.1/LC3/ Ki67/cyclin D1/Cav3.2/Glut1. Disease-free survival (DFS) and overall survival correlated inversely with overexpression of Cav3.2. DFS also correlated inversely with overexpression of Cav3.1. CONCLUSIONS TT-C immunoexpression on melanocytic neoplasms is consistent with our previous in vitro studies and appears to be related to tumour progression. TT-C upregulation can be considered as a prognostic marker using The Cancer Genome Atlas database. The high expression of Cav3.2 in metastatic melanoma encourages the investigation of the use of TT-C blockers in targeted therapies.

Abstract
AIMS Intracellular calcium (Ca(2+)) is known to play an important role in cancer development and growth. Resveratrol (Res) is a stilbene polyphenol occurring in several plant species and known for various possible beneficial effects, including its ability to inhibit proliferation and to induce apoptosis in cancer cells. This study was designed to determine whether Res affects Ca(2+) signaling in cancer cells. MAIN METHODS We used the REN human mesothelioma cell line, as an in vitro cancer cell model, and the non-malignant human mesothelial MeT5A cell line, as normal cell model. Cytosolic Ca(2+) concentration was measured by the fluorescent indicator Fura-2. Immunofluorescence, Western blot, and siRNA technique were employed to assess the involvement of T-type Ca(2+) channels. Cell viability was determined by the calcein assay. KEY FINDINGS REN cells transiently exposed to 1-10μM Res showed increasing peaks of Ca(2+) that were absent in Ca(2+)-free medium and were reduced by non-selective (Ni(2+)), and highly selective (NNC 55-0396) T-type Ca(2+) channels antagonist, and by siRNA knockout of Cav3.2T-type Ca(2+) channel gene. Dose-dependent curve of Res-induced Ca(2+) peaks showed a rightward shift in normal MeT-5A mesothelial cells (EC50=4.9μM) with respect to REN cells (EC50=2.7μM). Moreover, incubation with 3 and 10μM Res for 7days resulted in cell growth inhibition for REN, but not for MeT-5A cells. SIGNIFICANCE Res induces Ca(2+) influx, possibly mediated through T-type Ca(2+) channels, with significant selectivity towards mesothelioma cells, suggesting a possible use as an adjuvant to chemotherapy drugs for mesothelioma clinical treatment.

Abstract
Ovarian cancer is the deadliest gynecologic cancer, due in large part to the diagnosis of advanced stage disease, the development of platinum resistance, and inadequate treatment alternatives. Recent studies by our group and others have shown that T-type calcium (Ca(2+)) channels play a reinforcing role in cancer cell proliferation, cell-cycle progression, and apoptosis evasion. Therefore, we investigated whether T-type Ca(2+) channels affect ovarian tumor growth and response to platinum agents. Inhibition of T-type Ca(2+) channels with mibefradil or by silencing expression resulted in growth suppression in ovarian cancer cells with a simultaneous increase in apoptosis, which was accompanied by decreased expression of the antiapoptotic gene survivin (BIRC5). Analysis of intracellular signaling revealed mibefradil reduced AKT phosphorylation, increased the levels and nuclear retention of FOXO transcription factors that repress BIRC5 expression, and decreased the expression of FOXM1, which promotes BIRC5 expression. Combining carboplatin with mibefradil synergistically increased apoptosis in vitro. Importantly, mibefradil rendered platinum-resistant ovarian tumors sensitive to carboplatin in a mouse model of peritoneal metastasis. Together, the data provide rationale for future use of T-type channel antagonists together with platinum agents for the treatment of ovarian cancer.

Oleuropein-Enriched Olive Leaf Extract Affects Calcium Dynamics and Impairs Viability of Malignant Mesothelioma Cells. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2015; 2015:908493.

Abstract
Malignant mesothelioma is a poor prognosis cancer in urgent need of alternative therapies. Oleuropein, the major phenolic of olive tree (Olea europaea L.), is believed to have therapeutic potentials for various diseases, including tumors. We obtained an oleuropein-enriched fraction, consisting of 60% w/w oleuropein, from olive leaves, and assessed its effects on intracellular Ca2+ and cell viability in mesothelioma cells. Effects of the oleuropein-enriched fraction on Ca2+ dynamics and cell viability were studied in the REN mesothelioma cell line, using fura-2 microspectrofluorimetry and MTT assay, respectively. Fura-2-loaded cells, transiently exposed to the oleuropein-enriched fraction, showed dose-dependent transient elevations of cytosolic Ca2+ concentration ([Ca2+]i). Application of standard oleuropein and hydroxytyrosol, and of the inhibitor of low-voltage T-type Ca2+ channels NNC-55-0396, suggested that the effect is mainly due to oleuropein acting through its hydroxytyrosol moiety on T-type Ca2+ channels. The oleuropein-enriched fraction and standard oleuropein displayed a significant antiproliferative effect, as measured on REN cells by MTT cell viability assay, with IC50 of 22 μg/mL oleuropein. Data suggest that our oleuropein-enriched fraction from olive leaf extract could have pharmacological application in malignant mesothelioma anticancer therapy, possibly by targeting T-type Ca2+ channels and thereby dysregulating intracellular Ca2+ dynamics.

Abstract
Background T-type Ca2+ channels are often aberrantly expressed in different human cancers and participate in the regulation of cell cycle progression, proliferation and death. Methods: RT-PCR, Q-PCR, western blotting and whole-cell patch-clamp recording were employed to assess the expression of T-type Ca2+ channels in leukemia cell lines. The function of T-type Ca2+ channels in leukemia cell growth and the possible mechanism of the effect of T-type Ca2+ channel antagonists on cell proliferation and apoptosis were examined in T-lymphoma cell lines. Results We show that leukemia cell lines exhibited reduced cell growth when treated with T-type Ca2+ channel inhibitors, mibefradil and NNC-55-0396 in a concentration-dependent manner. Mechanistically, these inhibitors played a dual role on cell viability: (i) blunting proliferation, through a halt in the progression to the G1-S phase; and (ii) promoting cell apoptosis, partially dependent on the endoplasmic reticulum Ca2+ release. In addition, we observed a reduced phosphorylation of ERK1/2 in MOLT-4 cells in response to mibefradil and NNC-55-0396 treatment. Conclusions These results indicate that mibefradil and NNC-55-0396 regulate proliferation and apoptosis in T-type Ca2+ channel expressing leukemia cell lines and suggest a potential therapeutic target for leukemia.

Abstract
Ovarian carcinoma is the leading cause of death from gynecologic cancer in the developed world and is characterized by acquired chemoresistance leading to an overall 5-year survival rate of about 30 %. We previously showed that Bcl-xL and Mcl-1 cooperatively protect platinum-resistant ovarian cancer cells from apoptosis. Despite BH3-mimetics represent promising drugs to target Bcl-xL, anti-Mcl-1 strategies are still in pre-clinical studies and required new investigations. Calcium is a universal second messenger and dysregulation of calcium signal is often observed during carcinogenesis. As change in cytosolic free calcium concentration [Ca(2+)]i is known to control the fate of the cell by regulating Bcl-2 family members, we wonder if calcium signal could impact on Mcl-1 expression and if its pharmacological inhibition could be useful to sensitize ovarian carcinoma cells to anti-Bcl-xL strategies. We therefore studied the effect of different calcium signals inhibitors in ovarian carcinoma cell lines SKOV3 and IGROV1-R10 and analysed their effects on proliferation and Mcl-1 expression. We also exposed these cells to these inhibitors in combination with anti-Bcl-xL strategies (siRNA or BH3-mimetic: ABT-737). We found that calcium signaling regulates Mcl-1 through translational events and a calmodulin-mediated pathway. BAPTA-AM and calmodulin inhibitor combination with ABT-737 leads to apoptosis, a process that is reversed by Mcl-1 enforced expression. As Mcl-1 represents a crucial hurdle to the success of chemotherapy, these results could open to new area of investigation using calcium modulators to directly or indirectly target Mcl-1 and thus efficiently sensitize ovarian carcinoma cells to anti-Bcl-xL strategies.

Abstract
We used MCF-7 human breast cancer cells that endogenously express Cav3.1 and Cav3.2 T-type Ca(2+) channels toward a mechanistic study on the effect of EGCG on [Ca(2+)]i. Confocal Ca(2+) imaging showed that EGCG induces a [Ca(2+)]i spike which is due to extracellular Ca(2+) entry and is sensitive to catalase and to low-specificity (mibefradil) and high-specificity (Z944) T-type Ca(2+)channel blockers. siRNA knockdown of T-type Ca(2+) channels indicated the involvement of Cav3.2 but not Cav3.1. Application of EGCG to HEK cells expressing either Cav3.2 or Cav3.1 induced enhancement of Cav3.2 and inhibition of Cav3.1 channel activity. Measurements of K(+) currents in MCF-7 cells showed a reversible, catalase-sensitive inhibitory effect of EGCG, while siRNA for the Kv1.1 K(+) channel induced a reduction of the EGCG [Ca(2+)]i spike. siRNA for Cav3.2 reduced EGCG cytotoxicity to MCF-7 cells, as measured by calcein viability assay. Together, data suggest that EGCG promotes the activation of Cav3.2 channels through K(+) current inhibition leading to membrane depolarization, and in addition increases Cav3.2 currents. Cav3.2 channels are in part responsible for EGCG inhibition of MCF-7 viability, suggesting that deregulation of [Ca(2+)]i by EGCG may be relevant in breast cancer treatment.

Abstract
The anti-proliferative and apoptotic activities of new T-type calcium channel antagonist, 6e (BK10040) on human lung adenocarcinoma A549 cells were investigated. The MTT assay results indicated that BK10040 was cytotoxic against human lung adenocarcinoma (A549) and pancreatic cancer (MiaPaCa2) cells in a dose-dependent manner with IC50 of 2.25 and 0.93μM, respectively, which is ca. 2-fold more potent than lead compound KYS05090 despite of its decreased T-type calcium channel blockade. As a mode of action for cytotoxic effect of BK10040 on lung cancer (A549) cells, this cancer cell death was found to have the typical features of apoptosis, as evidenced by the accumulation of positive cells for annexin V. In addition, BK10040 triggered the activations of caspases 3 and 9, and the cleavages of poly (ADP-ribose) polymerase (PARP). Moreover, the treatment with z-VAD-fmk (a broad spectrum caspase inhibitor) significantly prevented BK10040-induced apoptosis. Based on these results, BK10040 may be used as a potential therapeutic agent for human lung cancer via the potent apoptotic activity.

Abstract
T-type calcium channels are involved in a multitude of cellular processes, both physiological and pathological, including cancer. T-type channels are also often aberrantly expressed in different human cancers and participate in the regulation of cell cycle progression, proliferation, migration, and survival. Here, we review the recent literature and discuss the controversies, supporting the role of T-type Ca(2+) channels in cancer cells and the proposed use of channels blockers as anticancer agents. A growing number of reports show that pharmacological inhibition or RNAi-mediated downregulation of T-type channels leads to inhibition of cancer cell proliferation and increased cancer cell death. In addition to a single agent activity, experimental results demonstrate that T-type channel blockers enhance the anticancer effects of conventional radio- and chemotherapy. At present, the detailed biological mechanism(s) underlying the anticancer activity of these channel blockers is not fully understood. Recent findings and ideas summarized here identify T-type Ca(2+) channels as a molecular target for anticancer therapy and offer new directions for the design of novel therapeutic strategies employing channels blockers. Physiological relevance: T-type calcium channels are often aberrantly expressed or deregulated in cancer cells, supporting their proliferation, survival, and resistance to treatment; therefore, T-type Ca(2+) channels could be attractive molecular targets for anticancer therapy.

Abstract
Ca(2+) plays a key role in intracellular signaling and controls various cellular processes such as proliferation, differentiation, cell growth, death, and apoptosis. Aberrant changes in intracellular Ca(2+) levels can promote undesired cell proliferation and migration and are therefore associated with certain tumor types. Many research groups have suggested a potential role for voltage-gated Ca(2+) channels in the regulation of tumor growth and progression, particularly T-type channels due to their unique biophysical properties. T-type channels are expressed in normal tissues throughout the body and in different types of tumors such as breast carcinoma, retinoblastoma, neuroblastoma, and glioma. It has been demonstrated that increased functional expression of the α1 subunit of T-type channels plays a role in the abnormal proliferation of glioblastoma cells. As such, siRNA-mediated knockdown of the expression of the α1 subunit of T-type channels decreases the proliferation of these cells. Moreover, pharmacological blockade of T-type channels significantly decreases tumor growth. In this review, we focus on the use of T-type channel blockers for the potential treatment of cancers, particularly highly proliferative tumors such as glioblastoma. We conclude that T-type channel blockers such as endostatin can serve as a potential therapeutic tool for tumors whose proliferation depends on increased T-type channel expression.

Abstract
We have recently reported that human melanoma cells express a variety of voltage-gated calcium (Ca(2+) ) channel types, including low-voltage-activated T-type channels that play a significant role in melanoma cell cycle progression. Here, we challenged melanoma metastatic cells with T-type channel blockers of clinical use and found a dual effect on cell viability: (i) a reduction in the proliferation rate, through a halt in the progression to the G1 -S phase; and (ii) a promotion of cell death that was partially dependent on the activation of caspases. An in-depth analysis of the death process showed that the apoptotic pathway is preceded by endoplasmic reticulum stress and the subsequent inhibition of the basal macroautophagy which is active in these cells. The effects of pharmacological blockers on Ca(2+) homeostasis, autophagy, and cell death were mimicked by T-type channel gene silencing. These results provide the basis for a new pharmacological and/or gene silencing approach toward tackling melanoma metastasis.

Abstract
The growth inhibition of human cancer cells via T-type Ca(2+) channel blockade has been well known. Herein, a series of new 3,4-dihydroquinazoline derivatives were synthesized via a brief SAR study on KYS05090 template and evaluated for both T-type Ca(2+) channel (Cav3.1) blockade and cytotoxicity on three human ovarian cancer cells (SK-OV-3, A2780 and A2780-T). Most of compounds except 6i generally exhibited more potent cytotoxicity on SK-OV-3 than mibefradil as a positive control regardless of the degree of T-type channel blockade. In particular, eight compounds (KYS05090, 6a and 6c-6h) showing strong channel blockade exhibited almost equal and more potent cytotoxicity on A2780 when compared to mibefradil. On A2780-T paclitaxel-resistant human ovarian carcinoma, two compounds (KYS05090 and 6d) were 20-fold more active than mibefradil. With respect to cell cycle arrest effect on A2780 and A2780-T cells, KYS05090 induced large proportion of sub-G1 phase in the cell cycle progression of A2780 and A2780-T, meaning the induction of cancer cell death instead of cell cycle arrest via blocking T-type Ca(2+) channel. Among new analogues, compounds 6g and 6h induced cell cycle arrest at G1 phase of A2780 and A2780-T cells in dose-dependent manner and exhibited strong anti-proliferation effects of ovarian cancer cells by blocking T-type Ca(2+) channel. Furthermore, 6g and 6h possessing strong cytotoxic effects could induce apoptosis of A2780 cells, which was detected by confocal micrographs using DAPI staining.

Abstract
OBJECT The survival of patients with high-grade gliomas remains unfavorable. Mibefradil, a T-type calcium channel inhibitor capable of synchronizing dividing cells at the G1 phase, has demonstrated potential benefit in conjunction with chemotherapeutic agents for gliomas in in vitro studies. In vivo study of mibefradil and radiosurgery is lacking. The authors used an intracranial C6 glioma model in rats to study tumor response to mibefradil and radiosurgery. METHODS Two weeks after implantation of C6 cells into the animals, each rat underwent MRI every 2 weeks thereafter for 8 weeks. After tumor was confirmed on MRI, the rats were randomly assigned to one of the experimental groups. Tumor volumes were measured on MR images. Experimental Group 1 received 30 mg/kg of mibefradil intraperitoneally 3 times a day for 1 week starting on postoperative day (POD) 15; Group 2 received 8 Gy of cranial radiation via radiosurgery delivered on POD 15; Group 3 underwent radiosurgery on POD 15, followed by 1 week of mibefradil; and Group 4 received mibefradil on POD 15 for 1 week, followed by radiosurgery sometime from POD 15 to POD 22. Twenty-seven glioma-bearing rats were analyzed. Survival was compared between groups using Kaplan-Meier methodology. RESULTS Median survival in Groups 1, 2, 3, and 4 was 35, 31, 43, and 52 days, respectively (p = 0.036, log-rank test). Two animals in Group 4 survived to POD 60, which is twice the expected survival of untreated animals in this model. Analysis of variance and a post hoc test indicated no tumor volume differences on PODs 15 and 29. However, significant volume differences were found on POD 43; mean tumor volumes for Groups 1, 2, 3, and 4 were 250, 266, 167, and 34 mm(3), respectively (p = 0.046, ANOVA). A Cox proportional hazards regression test showed survival was associated with tumor volume on POD 29 (p = 0.001) rather than on POD 15 (p = 0.162). In vitro assays demonstrated an appreciable and dose-dependent increase in apoptosis between 2- and 7-μM concentrations of mibefradil. CONCLUSIONS Mibefradil response is schedule dependent and enhances survival and reduces glioblastoma when combined with ionizing radiation.

Abstract
PURPOSE N-myc downstream-regulated gene 1 (NDRG1) reportedly regulates tumor progression in various cancers. Our previous studies showed that NDRG1 was aberrantly overexpressed in human endometrial cancer tissues. The purpose of the present study was to investigate the role of NDRG1 in endometrial carcinogenesis. METHODS A short hairpin RNA (shRNA)-mediated gene silencing strategy was employed to stably suppress the expression of NDRG1 in endometrial cancer Ishikawa cells. The influence of NDRG1 silencing on cancer cell biological behaviors was examined through observing in vitro tumor cell proliferation, colony formation, cell migration and invasion. Moreover, the mammalian NDRG1 expression vector pcDNA3.1(+)/NDRG1 was constructed to determine the effects of NDRG1 overexpression on cell proliferation and migration. Additionally, gene expression microarray analysis was conducted to identify NDRG1 downstream target genes after NDRG1 knockdown. RESULTS It was demonstrated that NDRG1 knockdown significantly enhanced Ishikawa cell proliferation and dramatically promoted cell migration and invasion. Furthermore, overexpression of NDRG1 in Ishikawa cells greatly inhibited cell proliferation and migration. Through microarray analysis and data mining, a large cohort of NDRG1-repressed target genes were identified. Additionally, through comparing the current microarray results with those obtained previously in studies of cervical and ovarian cancer cells conducted by us, 19 more specific common downstream target genes were identified. CONCLUSIONS It was demonstrated that NDRG1 might carry out a tumor suppressor function during endometrial carcinogenesis. The identification of downstream target genes should afford meaningful hints for prospective investigations. The tumor suppressor function of NDRG1 may open a new window for the target therapy of endometrial cancer.

Abstract
T-type calcium channels (Ca(V)3) play an important role in many physiological and pathological processes, including cancerogenesis. Ca(V)3 channel blockers have been proposed as potential cancer treatments. Roscovitine, a trisubstituted purine, is a cyclin-dependent kinase (CDK) inhibitor that is currently undergoing phase II clinical trials as an anticancer drug and has been shown to affect calcium and potassium channel activity. Here, we investigate the effect of roscovitine on Ca(V)3.1 channels. Ca(V)3.1 channels were transiently expressed in human embryonic kidney 293 cells, and currents were recorded by using the whole-cell patch-clamp technique. Roscovitine blocks Ca(V)3.1 channels with higher affinity for depolarized cells (EC₅₀ of 10 μM), which is associated with a negative shift in the voltage dependence of closed-state inactivation. Enhanced inactivation is mediated by roscovitine-induced acceleration of closed-state inactivation and slowed recovery from inactivation. Small effects of roscovitine were also observed on T-channel deactivation and open-state inactivation, but neither could explain the inhibitory effect. Roscovitine inhibits Ca(V)3.1 channels within the therapeutic range (10-50 μM) in part by stabilizing the closed-inactivated state. The ability of roscovitine to block multiple mediators of proliferation, including CDKs and Ca(V)3.1 channels, may facilitate its anticancer properties.
