Abstract
Sarcopenia induced by muscle aging is associated with negative outcomes in a variety of diseases. Long non-coding RNAs are a class of RNAs longer than 200 nucleotides with lower protein coding potential. An increasing number of studies have shown that lncRNAs play a vital role in skeletal muscle development. According to our previous research, lncRNA GPRC5D-AS1 is selected in the present study as the target gene to further study its effect on skeletal muscle aging in a dexamethasone-induced human muscle atrophy cell model. As a result, GPRC5D-AS1 functions as a ceRNA of miR-520d-5p to repress cell apoptosis and regulate the expression of muscle regulatory factors, including MyoD, MyoG, Mef2c and Myf5, thus accelerating myoblast proliferation and differentiation, facilitating development of skeletal muscle. In conclusion, lncRNA GPRC5D-AS1 could be a novel therapeutic target for treating sarcopenia.

Odongo R, Demiroglu-Zergeroglu A, Çakır T. A systems pharmacology approach based on oncogenic signalling pathways to determine the mechanisms of action of natural products in breast cancer from transcriptome data. BMC Complement Med Ther 2021; 21:181. [PMID: 34193143 PMCID: PMC8244196 DOI: 10.1186/s12906-021-03340-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Accepted: 06/02/2021] [Indexed: 12/16/2022] Open
Abstract
Background Narrow spectrum of action through limited molecular targets and unforeseen drug-related toxicities have been the main reasons for drug failures at the phase I clinical trials in complex diseases. Most plant-derived compounds with medicinal values possess poly-pharmacologic properties with overall good tolerability, and, thus, are appropriate in the management of complex diseases, especially cancers. However, methodological limitations impede attempts to catalogue targeted processes and infer systemic mechanisms of action. While most of the current understanding of these compounds is based on reductive methods, it is increasingly becoming clear that holistic techniques, leveraging current improvements in omic data collection and bioinformatics methods, are better suited for elucidating their systemic effects. Thus, we developed and implemented an integrative systems biology pipeline to study these compounds and reveal their mechanism of actions on breast cancer cell lines. Methods Transcriptome data from compound-treated breast cancer cell lines, representing triple negative (TN), luminal A (ER+) and HER2+ tumour types, were mapped on human protein interactome to construct targeted subnetworks. The subnetworks were analysed for enriched oncogenic signalling pathways. Pathway redundancy was reduced by constructing pathway-pathway interaction networks, and the sets of overlapping genes were subsequently used to infer pathway crosstalk. The resulting filtered pathways were mapped on oncogenesis processes to evaluate their anti-carcinogenic effectiveness, and thus putative mechanisms of action. Results The signalling pathways regulated by Actein, Withaferin A, Indole-3-Carbinol and Compound Kushen, which are extensively researched compounds, were shown to be projected on a set of oncogenesis processes at the transcriptomic level in different breast cancer subtypes. The enrichment of well-known tumour driving genes indicate that these compounds indirectly dysregulate cancer driving pathways in the subnetworks. Conclusion The proposed framework infers the mechanisms of action of potential drug candidates from their enriched protein interaction subnetworks and oncogenic signalling pathways. It also provides a systematic approach for evaluating such compounds in polygenic complex diseases. In addition, the plant-based compounds used here show poly-pharmacologic mechanism of action by targeting subnetworks enriched with cancer driving genes. This network perspective supports the need for a systemic drug-target evaluation for lead compounds prior to efficacy experiments.

Abstract
BACKGROUND Oral squamous cell carcinoma (OSCC) is among the most prevalent head and neck malignancies globally, and it is associated with high mortality rates. Actein is one of the primary active components extractable from the rhizomes of Cimicifuga foetida. This study aimed to evaluate the anti-OSCC effects of actein and evaluate the potential underlying mechanisms. METHODS AND RESULTS CCK-8 cell proliferation experiments demonstrated significant dose- and time-dependent anti-OSCC effects of actein, while actein had weak cytotoxic effects on normal oral cell lines. Flow cytometry for cell cycle evaluation revealed that actein could induce cell cycle arrest at the G1 phase among OSCC cell lines. In our Annexin V/PI double staining apoptosis analysis, actein induced significant apoptosis among OSCC cells, with upregulation of Bax and downregulation of Bcl-2. Our mechanistic study implicated the involvement of the Akt/FoxO1 pathway in the anti-OSCC effects of actein. Akt1 and Akt2 expression significantly decreased in association with the FoxO1 upregulation. Furthermore, Bim and p21 were significantly upregulated, while survivin expression was downregulated. Finally, actein treatment was associated with significant p-Akt downregulation and p-FoxO1 upregulation in OSCC cells, demonstrating the validated roles of Akt/FoxO1 in actein-mediated OSCC cell apoptosis and cell cycle arrest. FoxO1 knockdown significantly reversed the anti-OSCC effects of actein. Additionally, a xenograft model indicated that actein could inhibit OSCC cell growth in vivo. CONCLUSIONS Our findings demonstrated that actein could be a strong anti-OSCC candidate. Further evaluations of its safety and effectiveness are necessary before it can be considered for clinical use.

A narrative review of the migration and invasion features of non-small cell lung cancer cells upon xenobiotic exposure: insights from in vitro studies. Transl Lung Cancer Res 2021; 10:2698-2714. [PMID: 34295671 PMCID: PMC8264350 DOI: 10.21037/tlcr-21-121] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Accepted: 05/10/2021] [Indexed: 01/03/2023]
Abstract
Lung cancer (LC) is the leading cause of cancer deaths worldwide, being non-small lung cancer (NSCLC) sub-types the most prevalent. Since most LC cases are only detected during the last stage of the disease the high mortality rate is strongly associated with metastases. For this reason, the migratory and invasive capacity of these cancer cells as well as the mechanisms involved have long been studied to uncover novel strategies to prevent metastases and improve the patients’ prognosis. This narrative review provides an overview of the main in vitro migration and invasion assays employed in NSCLC research. While several methods have been developed, experiments using conventional cell culture models prevailed, specifically the wound-healing and the transwell migration and invasion assays. Moreover, it is provided herewith a summary of the available information concerning chemical contaminants that may promote the migratory/invasive properties of NSCLC cells in vitro, shedding some light on possible LC risk factors. Most of the reported agents with pro-migration/invasion effects derive from cigarette smoking [e.g., Benzo(a)pyrene and cadmium] and air pollution. This review further presents several studies in which different dietary/plant-derived compounds demonstrated to impair migration/invasion processes in NSCLC cells in vitro. These chemicals that have been proposed as anti-migratory consisted mainly of natural bioactive substances, including polyphenols non-flavonoids, flavonoids, bibenzyls, terpenes, alkaloids, and steroids. Some of these compounds may eventually represent novel therapeutic strategies to be considered in the future to prevent metastasis formation in LC, which highlights the need for additional in vitro methodologies that more closely resemble the in vivo tumor microenvironment and cancer cell interactions. These studies along with adequate in vivo models should be further explored as proof of concept for the most promising compounds.

Chalcomoracin inhibits cell proliferation and increases sensitivity to radiotherapy in human non-small cell lung cancer cells via inducing endoplasmic reticulum stress-mediated paraptosis. Acta Pharmacol Sin 2020; 41:825-834. [PMID: 32066885 PMCID: PMC7470873 DOI: 10.1038/s41401-019-0351-4] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2019] [Revised: 12/05/2019] [Accepted: 12/12/2019] [Indexed: 12/15/2022] Open
Abstract
Chalcomoracin (CMR) is a kind of Diels–Alder adduct extracted from the mulberry leaves. Recent studies showed that CMR has a broad spectrum of anticancer activities and induces paraptosis in breast cancer and prostate cancer cells. In this study, we investigated the effects of CMR against human non-small cell lung cancer cells and the underlying mechanisms. We found that CMR dose-dependently inhibited the proliferation of human lung cancer H460, A549 and PC-9 cells. Furthermore, exposure to low and median doses of CMR induced paraptosis but not apoptosis, which was presented as the formation of extensive cytoplasmic vacuolation with increased expression of endoplasmic reticulum stress markers, Bip and Chop, as well as activation of MAPK pathway in the lung cancer cells. Knockdown of Bip with siRNA not only reduced the cell-killing effect of CMR, but also decreased the percentage of cytoplasmic vacuoles in H460 cells. Moreover, CMR also increased the sensitivity of lung cancer cells to radiotherapy through enhanced endoplasmic reticulum stress. In lung cancer H460 cell xenograft nude mice, combined treatment of CMR and radiation caused greatly enhanced tumor growth inhibition with upregulation of endoplasmic reticulum stress proteins and activation of pErk in xenograft tumor tissue. These data demonstrate that the anticancer activity and radiosensitization effect of CMR result from inducing paraptosis, suggesting that CMR could be considered as a potential anticancer agent and radiation sensitizer in the future cancer therapeutics.

Abstract
HER2-positive breast cancer accounts for 15–20% in breast cancer and 50% of the metastatic HER2-positive breast cancer patients died of central nervous system progression. The present study investigated the effects of actein (a natural cycloartane triterpene) on cells adhesion, migration, proliferation and matrix degradation, and its underlying mechanism in HER2-positive breast cancer cells. The in vivo effect of actein on tumor growth and metastasis in MDA-MB-361 tumor-bearing mice as well as the anti-brain metastasis in tail vein injection mice model were also investigated. Our results showed that actein inhibited HER2-positive breast cancer cells viability, proliferation and migration. Actein also induced MDA-MB-361 cells G1 phase arrest and inhibited the expressions of cyclins and cyclin-dependent kinases. For intracellular mechanisms, actein inhibited the expressions of molecules in AKT/mTOR and Ras/Raf/MAPK signaling pathways. Furthermore, actein (15 mg/kg) was shown to exhibit anti-tumor and anti-metastatic activities in MDA-MB-361 breast tumor-bearing mice, and reduced brain metastasis in tail vein injection mice model. All these findings strongly suggested that actein is a potential anti-metastatic agent for HER2-positive breast cancer.

Abstract
Mammalian STE20-like kinase 1 (Mst1) is well recognized as a major tumor suppressor in cancer development, growth, metabolic reprogramming, metastasis, cell death and recurrence. However, the roles of Mst1 in non-small cell lung cancer (NSCLC) A549 cell phenotypic alterations remain to be elucidated. The present study aimed to explore the functional role and underlying mechanisms of Mst1 with regards to A549 cell proliferation, migration and apoptosis; this study focused on mitochondrial homeostasis and Rho-associated coiled-coil containing protein kinase 1 (ROCK1)/F‑actin pathways. The results demonstrated that Mst1 was downregulated in A549 cells compared with in a normal pulmonary epithelial cell line. Subsequently, overexpression of Mst1 in A549 cells reduced cell viability and promoted cell apoptosis. Furthermore, overexpression of Mst1 suppressed A549 cell proliferation and migration. At the molecular level, the reintroduction of Mst1 in A549 cells led to activation of mitochondrial apoptosis, as evidenced by a reduction in mitochondrial potential, overproduction of ROS, cytochrome c release from the mitochondria into the nucleus, and upregulation of pro-apoptotic protein expression. In addition, Mst1 overexpression was closely associated with impaired mitochondrial respiratory function and suppressed cellular energy metabolism. Functional studies illustrated that Mst1 overexpression activated ROCK1/F-actin pathways, which highly regulate mitochondrial function. Inhibition of ROCK1/F-actin pathways in A549 cells sustained mitochondrial homeostasis, alleviated caspase-9-dependent mitochondrial apoptosis, enhanced cancer cell migration and increased cell proliferation. In conclusion, these data firmly established the regulatory role of Mst1 in NSCLC A549 cell survival via the modulation of ROCK1/F-actin pathways, which may provide opportunities for novel treatment modalities in clinical practice.
