Lanatoside C Induces G2/M Cell Cycle Arrest and Suppresses Cancer Cell Growth by Attenuating MAPK, Wnt, JAK-STAT, and PI3K/AKT/mTOR Signaling Pathways
Biomolecules 2019 Nov 27;9(12):792.PMID:31783627DOI:10.3390/biom9120792.
Cardiac glycosides (CGs) are a diverse family of naturally derived compounds having a steroid and glycone moiety in their structures. CG molecules inhibit the α-subunit of ubiquitous transmembrane protein Na+/K+-ATPase and are clinically approved for the treatment of cardiovascular diseases. Recently, the CGs were found to exhibit selective cytotoxic effects against cancer cells, raising interest in their use as anti-cancer molecules. In this current study, we explored the underlying mechanism responsible for the anti-cancer activity of Lanatoside C against breast (MCF-7), lung (A549), and liver (HepG2) cancer cell lines. Using Real-time PCR, western blot, and immunofluorescence studies, we observed that (i) Lanatoside C inhibited cell proliferation and induced apoptosis in cell-specific and dose-dependent manner only in cancer cell lines; (ii) Lanatoside C exerts its anti-cancer activity by arresting the G2/M phase of cell cycle by blocking MAPK/Wnt/PAM signaling pathways; (iii) it induces apoptosis by inducing DNA damage and inhibiting PI3K/AKT/mTOR signaling pathways; and finally, (iv) molecular docking analysis shows significant evidence on the binding sites of Lanatoside C with various key signaling proteins ranging from cell survival to cell death. Our studies provide a novel molecular insight of anti-cancer activities of Lanatoside C in human cancer cells.
Lanatoside C Promotes Foam Cell Formation and Atherosclerosis
Sci Rep 2016 Jan 29;6:20154.PMID:26821916DOI:10.1038/srep20154.
Lanatoside C's impact on atherosclerosis is poorly understood. The present study was conducted to determine whether Lanatoside C affects the development of atherosclerosis in apolipoprotein E-deficient (ApoE(-/-)) mice. ApoE(-/-) mice were administered either phosphate-buffered saline (PBS) containing 0.1% DMSO (the vehicle control group) or Lanatoside C at low (1 mg/kg per day) or high (2 mg/kg per day) doses, and fed a Western diet for 12 weeks. Lanatoside C dose-dependently aggravated the development of atherosclerosis in the ApoE(-/-) mice compared with the vehicle control group. In an effort to determine the mechanism by which Lanatoside C increased atherosclerosis, we found that Lanatoside C significantly promoted the uptake of oxidised low-density lipoprotein (oxLDL) and increased foam-cell formation by upregulation of scavenger receptor class A (SR-A) and the class B scavenger receptor (CD36) in macrophages. Meanwhile, the effects of Lanatoside C were abolished using small interfering RNA (siRNA) inhibition of peroxisome proliferator-activated receptors β/δ (PPARβ/δ). Overall, our data demonstrate that Lanatoside C aggravates the development of atherosclerosis by inducing PPARβ/δ expression, which mediates upregulation of SR-A and CD36, and promotes oxLDL uptake and foam-cell formation.
Targeting the Otub1/c-Maf axis for the treatment of multiple myeloma
Blood 2021 Mar 18;137(11):1478-1490.PMID:32842143DOI:10.1182/blood.2020005199.
The oncogenic transcription factor c-Maf has been proposed as an ideal therapeutic target for multiple myeloma (MM), but how to achieve it is still elusive. In the present study, we found the Otub1/c-Maf axis could be a potential target. Otub1, an OTU family deubiquitinase, was found to interact with c-Maf by mass spectrometry. Otub1 abrogates c-Maf K48-linked polyubiquitination, thus preventing its degradation and enhancing its transcriptional activity. Specifically, this deubiquitinating activity depends on its Lys71 and the N terminus but is independent of UBE2O, a known E2 of c-Maf. Otub1 promotes MM cell survival and MM tumor growth. In contrast, silence of Otub1 leads to c-Maf degradation and c-Maf-expressing MM cell apoptosis. Therefore, the Otub1/c-Maf axis could be a therapeutic target of MM. In order to explore this concept, we performed a c-Maf recognition element-driven luciferase-based screen against US Food and Drug Administration-approved drugs and natural products, from which the generic cardiac glycoside Lanatoside C (LanC) is found to prevent c-Maf deubiquitination and induces its degradation by disrupting the interaction of Otub1 and c-Maf. Consequently, LanC inhibits c-Maf transcriptional activity, induces c-Maf-expressing MM cell apoptosis, and suppresses MM growth and prolongs overall survival of model mice, but without apparent toxicity. Therefore, the present study identifies Otub1 as a novel deubiquitinase of c-Maf and establishes that the Otub1/c-Maf axis is a potential therapeutic target for MM.
Lanatoside C protects mice against bleomycin-induced pulmonary fibrosis through suppression of fibroblast proliferation and differentiation
Clin Exp Pharmacol Physiol 2019 Jun;46(6):575-586.PMID:30854687DOI:10.1111/1440-1681.13081.
It has been established that Lanatoside C, a FDA-approved cardiac glycoside, reduces proliferation of cancer cell lines. The proliferation of fibroblasts is critical to the pathogenesis of pulmonary fibrosis (PF), a progressive and fatal fibrotic lung disease lacking effective treatment. In this study we have investigated the impact of Lanatoside C on a bleomycin (BLM)-induced mouse model of PF and through the evaluation of fibroblast proliferation and activation in vitro. We evaluated explanted lung tissue by histological staining, western blot analysis, qRT-PCR and survival analysis, demonstrating that Lanatoside C was able to protect mice against BLM-induced pulmonary fibrosis. The proliferation of cultured pulmonary fibroblasts isolated from BLM-induced PF mice was suppressed by Lanatoside C, as hypothesized, through the induction of cell apoptosis and cell cycle arrest at the G2/M phase. The Akt signalling pathway was involved in this process. Interestingly, the production of α-SMA, fibronectin, and collagen I and III in response to TGF-β1 in healthy mouse fibroblasts was suppressed following Lanatoside C administration by inhibition of TGF-β1/Smad signalling. In addition, TGF-β1-induced migration in lung fibroblasts was also impeded after Lanatoside C treatment. Together, our data revealed that Lanatoside C alleviated BLM-induced pulmonary fibrosis in mice via attenuation of growth and differentiation of fibroblasts, suggesting that it has potential as a candidate therapy for PF patients.
Lanatoside C inhibits human cervical cancer cell proliferation and induces cell apoptosis by a reduction of the JAK2/STAT6/SOCS2 signaling pathway
Oncol Lett 2021 Oct;22(4):740.PMID:34466152DOI:10.3892/ol.2021.13001.
Cervical cancer is one of the leading causes of cancer-associated mortality in gynecological diseases and ranks third among female cancers worldwide. Although early detection and vaccination have reduced incidence rates, cancer recurrence and metastasis lead to high mortality due to the lack of effective medicines. The present study aimed to identify novel drug candidates to treat cervical cancer. In the present study, Lanatoside C, an FDA-approved cardiac glycoside used for the treatment of heart failure, was demonstrated to have anti-proliferative and cytotoxic effects on cervical cancer cells, with abrogation of cell migration in a dose-dependent manner. Lanatoside C also triggered cell apoptosis by enhancing reactive oxygen species production and reducing the mitochondrial membrane potential, which induced cell cycle arrest at the S and G2/M phases. Furthermore, Lanatoside C inhibited the phosphorylation of Janus kinase 2 (JAK2) and signal transducer and activator of transcription 6 (STAT6), while inducing the expression of suppressor of cytokine signaling 2, a negative regulator of JAK2-STAT6 signaling. Taken together, the results of the present study suggest that Lanatoside C suppresses cell proliferation and induces cell apoptosis by inhibiting JAK2-STAT6 signaling, indicating that Lanatoside C is a promising agent for the treatment of cervical cancer.
