Abstract Background Circular RNAs (circRNAs), a novel class of endogenous RNAs, have shown to participate in the development of breast cancer (BC). Hsa_circ_0005273 is a circRNA generated from several exons of PTK2. However, the potential functional role of hsa_circ_0005273 in BC remains largely unknown. Here we aim to evaluate the role of hsa_circ_0005273 in BC. Methods The expression level of hsa_circ_0005273 and miR-200a-3p were examined by RT-qPCR in BC tissues and cell lines. The effect of knocking down hsa_circ_0005273 in BC cell lines were evaluated by examinations of cell proliferation, migration and cell cycle. In addition, xenografts experiment in nude mice were performed to evaluate the effect of hsa_circ_0005273 in BC. RNA immunoprecipitation assay, RNA probe pull-down assay, luciferase reporter assay and fluorescence in situ hybridization were conducted to confirm the relationship between hsa_circ_0005273, miR-200a-3p and YAP1. Results Hsa_circ_0005273 is over-expressed in BC tissues and cell lines, whereas miR-200a-3p expression is repressed. Depletion of hsa_circ_0005273 inhibited the progression of BC cells in vitro and in vivo, while overexpression of hsa_circ_0005273 exhibited the opposite effect. Importantly, hsa_circ_0005273 upregulated YAP1 expression and inactivated Hippo pathway via sponging miR-200a-3p to promote BC progression. Conclusions Hsa_circ_0005273 regulates the miR-200a-3p/YAP1 axis and inactivates Hippo signaling pathway to promote BC progression, which may become a potential biomarker and therapeutic target.

Abstract Abemaciclib is the newest cyclin-dependent kinase 4/6 inhibitor that has received approval from the US Food and Drug Administration for using in patients with advanced breast cancer. However, its potential adverse effects on cardiomyocytes remain unknown. In this study, we used the cell counting kit-8 assay, western blot analysis, flow cytometry, immunostaining, and quantitative polymerase chain reaction to investigate the role of abemaciclib in inducing apoptosis and in inhibiting the viability and proliferation of AC16 human cardiomyocyte cells. The results revealed that abemaciclib induced apoptosis and inhibited cell proliferation by activating the Hippo signaling pathway. This work demonstrates the molecular basis by which abemaciclib induces cardiac side effects, providing a theoretical basis and effective targets for the treatment of cardiac diseases.

The Hippo Pathway

The Hippo pathway is an emerging tumor suppressor signaling pathway involved in a wide range of cellular processes. Dysregulation of different components of the Hippo signaling pathway is associated with a number of diseases including cancer. Therefore, identification of the Hippo pathway regulators and the underlying mechanism of its regulation may be useful to uncover new therapeutics for cancer therapy. The Hippo signaling pathway includes a set of kinases that phosphorylate different proteins in order to phosphorylate and inactivate its main downstream effectors, YAP and TAZ. Thus, modulating phosphorylation and dephosphorylation of the Hippo components by kinases and phosphatases play critical roles in the regulation of the signaling pathway. While information regarding kinase regulation of the Hippo pathway is abundant, the role of phosphatases in regulating this pathway is just beginning to be understood. In this review, we summarize the most recent reports on the interaction of phosphatases and the Hippo pathway in tumorigenesis. We have also introduced challenges in clarifying the role of phosphatases in the Hippo pathway and future direction of crosstalk between phosphatases and the Hippo pathway.

Physiological Cardiac Hypertrophy

Introduction: The role of Hippo signaling pathway, which was identified by genetic studies as a key regulator for tissue growth and organ size, in promoting physiological cardiac hypertrophy has not been investigated. Methods: Fourteen male Wistar rats were randomly assigned to the exercise and control groups. The exercise group ran 1 hour per day, 5 days/week, at about 65%-75% VO2max on the motor-driven treadmill with 15º slope, and the control group ran 15 min/d, 2 days/week at 9 m/min (0º inclination), throughout the eight-week experimental period. Forty-eight hours after the last session, hearts were dissected and left ventricles were weighed and stored for subsequent RT-PCR analysis. Results: Despite a significant increase in the MAP4k1 expression levels in the exercise group (P = 0.001), the Mst1 expression was inhibited compared to the control group (P < 0.001) which was followed by suppression of Lats1 expression (P = 0.001). Compared with the control group, significant increases were observed in heart weight/body weight (P = 0.024) and left ventricular weight/body weight (P = 0.034) ratios in the exercise group. The H&E staining confirmed the cardiac hypertrophy that may be partly due to a significant increase in Yap1 expression level compared with the control group (P<0.001), which was confirmed by Western blot analysis. Conclusion: Increased MAP4K1 expression did not influence Lats1 activation. The exercise training protocol suppressed Mst1 and Lats1 (Hippo pathway) and caused an increase in Yap1 expression level, which led to physiological cardiac hypertrophy in healthy rats. Further studies are suggested to apply this exercise protocol for the prevention and/or rehabilitation of cardiovascular disease and health promotion.
