Abstract
Aberrant activation of Wnt pathway is linked to dysregulation of several genes. DACT1 and DACT2 are members of the DACT family that participate in antagonizing of the Wnt signaling cascade. Thus in this study, we assessed the mRNA levels of DACT1, DACT2, and CYCLIN D1 in 70 pairs of CRC tissues compared to the adjacent tissues. Determination of the mRNA levels of DACT1, DACT2, and CYCLIN D1 was done by Quantitative Real-Time PCR (qRT-PCR). The correlation between DACT1, DACT2, and CYCLIN D1 genes was also examined. Receiver operating characteristic (ROC) curves was plotted to assess the diagnostic power. The association between histopathological parameters and the DACT1, DACT2, and CYCLIN D1 genes was investigated. The expression levels of DACT1 and CYCLIN D1 were remarkably higher in CRC tissues compared to the adjacent tissues (p < 0.0001). However, the expression of DACT2 was decreased (p < 0.001). Our results showed a significant correlation between the expression of DACT1 and CYCLIN D1 (p < 0.0001). DACT1 (AUC = 0.74, p < 0.0001), DACT2 (AUC = 0.69, p < 0.0003), and CYCLIN D1 (AUC = 0.75, p < 0.0001) had good effectiveness in separation between CRC samples and adjacent tissues. We found a significant association between DACT1 expression with tumor site (p < 0.01). Also, a significant association was detected between DACT2 and CYCLIN D1 with tumor stage (p < 0.005 and p < 0.038, respectively). The findings suggested that DACT1 could function as an oncogene, whereas DACT2 was downregulated and can be considered as a tumor suppressor in CRC.

A combination of the PI3K pathway inhibitor plus cell cycle pathway inhibitor to combat endocrine resistance in hormone receptor-positive breast cancer: a genomic algorithm-based treatment approach.

Abstract
Cyclin-dependent kinase 4 (CDK4) and CDK6 together with D-type cyclins (D1, D2 and D3) to promote cell cycle entry and progression through G1 by inactivating retinoblastoma protein (RB) by inhibiting an INK4 family of CDK inhibitors (CDKN2A/B). Selective cyclin-dependent kinase inhibitors are game changers in the clinical management of hormone receptor-positive/HER2-negative advanced breast cancers. There are currently three CDK4/6 inhibitors that have been approved by the US Food and Drug administration: palbociclib, ribociclib, and abemaciclib. Although, the bulk of the data supporting the use of selective CDK4/6 inhibitors is currently in breast cancer patients with other tumor types are expected to benefit as well from this class of agents, which can counter proliferative signaling pathways and arrest cell cycle in early G1 phase. Areas of active interest include identifying predictive biomarkers for CDK4/6 inhibitors, deciding whether to continue CDK4/6 inhibitor after disease progression, creating novel treatment combinations and expanding the use of CDK4/6 inhibitors beyond hormone receptor-positive/HER2-negative advanced breast cancer. Right now, CCND1 amplification and CDKN2A/B loss have not sorted out biomarkers useful for the purpose. One of the most important clinical questions is how to use a CDK4/6 inhibitor with other targeted therapies. Here we provide a rationale that oncologists can use to sequence the CDK4/6 inhibitors along with the PI3K-AKT-mTOR pathway-specific inhibitor(s); future data will better guide this approach. In this review we have tried to (a) describe the specific cellular signals initiated following alterations in the cell cycle pathway genes and the PI3K pathway genes, (b) interrogate how these alterations/co-alterations influence the action of PI3K and cell cycle pathway-targeted drugs in different clinical trials and (c) understand the role of co-alterations towards the development of cell cycle inhibitors induced drug-resistance in ER+ breast cancers.

Abstract
This study investigated the effects of cyclin D1 gene silencing on cell proliferation and apoptosis of interleukin-1β (IL-1β)-induced osteoarthritis (OA) chondrocytes. Chondrocytes from healthy sprague-dawley rats were divided into blank, OA model (chondrocytes underwent IL-1β inducement), OA trial (chondrocytes underwent IL-1β inducement with cyclin D1-shRNA treatment), and negative control (NC; chondrocytes underwent IL-1β inducement and control-shRNA treatment) groups. Cell proliferation was assessed by CCK-8 assay, and cell cycle and apoptosis by flow cytometry. qRT-PCR and Western blotting were performed to detect cyclin D1 and apoptosis-related factors expression levels. Chondrocyte proliferation increased after 72-96 h after incubation. The OA trial group exhibited reduced cell proliferation at 48, 72, and 96 h after treatment. The OA model, OA trial, and NC groups all contained more cells arrested in G1 phase and had higher apoptosis rates than the blank group. Additionally, the OA trial group contained more cells arrested in G1 phase, with increased apoptosis rates compared to the OA model and NC groups. The OA model group had lowest expression of cyclin D1 whereas the blank group contained the highest among the four groups. qRT-PCR also showed that the OA model, OA trial, and NC groups all had increased expression levels of Bax and reduced expression levels of Bcl-2 and P53 compared to the blank group, whereby by the OA group had the most significant change. The combined evidence in our study shows that cyclin D1 gene silencing suppresses proliferation and induces apoptosis of rat chondrocytes in IL-1β-induced OA. J. Cell.

Abstract
Nonhuman primates are useful animal models for the study of human diseases. However, the number of established cell lines from nonhuman primates is quite limited compared with the number established from other experimental animals. The establishment of nonhuman primate cell lines would allow drug testing on those cell lines before moving experiments into primates. In this study, we established nonhuman primate primary cell lines by introducing the genes for CDK4R24C, cyclin D1, and hTERT. These cell lines proliferated more rapidly than primary cells and bypassed cellular senescence. Karyotype analysis showed that the chromosome patterns were intact in the immortalized cell lines. Furthermore, we showed that the expression of introduced genes could be precisely controlled through the Tet-Off system with the addition of doxycycline. The present study shows that introduction of the CDK4R24C, cyclin D1, and hTERT genes are effective methods of establishing nonhuman primate cell lines.

Abstract
Abnormal proliferation of vascular smooth muscle cells (VSMCs) is a common feature of disease progression in atherosclerosis. Cell proliferation is regulated by cell cycle regulatory proteins. MicroRNAs (miR) have been reported to act as important gene regulators and play essential roles in the proliferation and migration of VSMCs in a cardiovascular disease. However, the roles and mechanisms of miRs in VSMCs and neointimal formation are far from being fully understood. In this study, cell cycle-specific cyclin D1 was found to be a potential target of miR-365 by direct binding. Through an in vitro experiment, we showed that exogenous miR-365 overexpression reduced VSMC proliferation and proliferating cell nuclear antigen (PCNA) expression, while miR-365 was observed to block G1/S transition in platelet-derived growth factor-bb (PDGF-bb)-induced VSMCs. In addition, the proliferation of VSMCs by various stimuli, including PDGF-bb, angiotensin II (Ang II), and serum, led to the downregulation of miR-365 expression levels. The expression of miR-365 was confirmed in balloon-injured carotid arteries. Taken together, our results suggest an anti-proliferative role for miR-365 in VSMC proliferation, at least partly via modulating the expression of cyclin D1. Therefore, miR-365 may influence neointimal formation in atherosclerosis patients.

Abstract
Insulin is a secreted peptide hormone identified in human pancreas to promote glucose utilization. Insulin has been observed to induce cell proliferation and myogenesis in C2C12 cells. The precise mechanisms underlying the proliferation of C2C12 cells induced by insulin remain unclear. In this study, we observed for the first time that 10 nM insulin treatment promotes C2C12 cell proliferation. Additionally, 50 and 100 nM insulin treatment induces C2C12 cell apoptosis. By utilizing real-time PCR and Western blotting analysis, we found that the mRNA levels of cyclinD1 and BAD are induced upon 10 and 50 nM/100 nM insulin treatment, respectively. The similar results were observed in C2C12 cells expressing GATA-6 or PPARα. Our results identify for the first time the downstream targets of insulin, cyclin D1, and BAD, elucidate a new molecular mechanism of insulin in promoting cell proliferation and apoptosis.
