Abstract
Although fangchinoline has been widely used as an adjunct therapy for a variety of inflammatory and cancerous diseases, its mechanism of action on tumor cells remains unclear. Fangchinoline derivative LYY-35 reduced the number of A549 cells, deformed cell morphology and increased cell debris. Cell viability was significantly reduced, while the same concentration of LYY-35 had little effect on BEAS-2B viability of normal lung epithelial cells. In addition, LYY-35 can also reduce the migration, proliferation and invasion ability of A549 cells. Levels of β-catenin, ZO-1 and ZEB-1 proteins, biomarkers of cell adhesion and epithelial mesenchymal transformation, were significantly reduced. The levels of superoxide dismutase and lactate dehydrogenase decreased gradually, while the levels of glutathione, malondialdehyde and intracellular and extracellular ROS increased significantly. At the same time, LYY-35 induced increased apoptosis, increased expression of Bax, cleaved caspase3, cleaved PARP1, and decreased expression of Bcl-xl, which blocked the cell cycle to G0/G1 phase. The expressions of cell cycle checkpoint proteins Cyclin B1, Cyclin E1, CDK6, PCNA and PICH were significantly decreased. With the increase of LYY-35 concentration, the trailing phenomenon was more obvious in single cell gel electrophoresis. DNA damage repair proteins: BLM, BRCA-1 and PARP-1 expression decreased gradually.LYY-35 can inhibit the proliferation of non-small cell lung cancer A549 cells, block cell cycle, promote apoptosis, increase ROS production, cause DNA damage and interfere with DNA replication. LYY-35 is promising for the treatment of non-small cell lung cancer in the future.

Biomolecules Involved in Both Metastasis and Placenta Accreta Spectrum-Does the Common Pathophysiological Pathway Exist? Cancers (Basel) 2023; 15:cancers15092618. [PMID: 37174083 PMCID: PMC10177254 DOI: 10.3390/cancers15092618] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 05/01/2023] [Accepted: 05/03/2023] [Indexed: 05/15/2023] Open
Abstract
The process of epithelial-to-mesenchymal transition (EMT) is crucial in the implantation of the blastocyst and subsequent placental development. The trophoblast, consisting of villous and extravillous zones, plays different roles in these processes. Pathological states, such as placenta accreta spectrum (PAS), can arise due to dysfunction of the trophoblast or defective decidualization, leading to maternal and fetal morbidity and mortality. Studies have drawn parallels between placentation and carcinogenesis, with both processes involving EMT and the establishment of a microenvironment that facilitates invasion and infiltration. This article presents a review of molecular biomarkers involved in both the microenvironment of tumors and placental cells, including placental growth factor (PlGF), vascular endothelial growth factor (VEGF), E-cadherin (CDH1), laminin γ2 (LAMC2), the zinc finger E-box-binding homeobox (ZEB) proteins, αVβ3 integrin, transforming growth factor β (TGF-β), β-catenin, cofilin-1 (CFL-1), and interleukin-35 (IL-35). Understanding the similarities and differences in these processes may provide insights into the development of therapeutic options for both PAS and metastatic cancer.

Moesin Serves as Scaffold Protein for PD-L1 in Human Uterine Cervical Squamous Carcinoma Cells. J Clin Med 2022; 11:jcm11133830. [PMID: 35807113 PMCID: PMC9267616 DOI: 10.3390/jcm11133830] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2022] [Revised: 06/17/2022] [Accepted: 06/30/2022] [Indexed: 02/04/2023] Open
Abstract
Immune checkpoint blockade (ICB) therapy targeting the programmed death ligand-1 (PD-L1)/PD-1 axis has emerged as a promising treatment for uterine cervical cancer; however, only a small subset of patients with uterine cervical squamous cell carcinoma (SCC) derives clinical benefit from ICB therapies. Thus, there is an urgent unmet medical need for novel therapeutic strategies to block the PD-L1/PD-1 axis in patients with uterine cervical SCC. Here, we investigated the involvement of ezrin/radixin/moesin (ERM) family scaffold proteins, which crosslink several plasma membrane proteins with the actin cytoskeleton, on the plasma membrane localization of PD-L1 in BOKU and HCS-2 cells derived from human uterine cervical SCC. Immunofluorescence analysis showed that PD-L1 colocalized with all three ERM proteins in the plasma membrane. Gene knockdown of moesin, but not ezrin and radixin, substantially reduced the plasma membrane expression of PD-L1, with limited effect on mRNA expression. An immunoprecipitation assay demonstrated the molecular interaction between PD-L1 and moesin. Moreover, phosphorylated, i.e., activated, moesin was highly colocalized with PD-L1 in the plasma membrane. In conclusion, moesin may be a scaffold protein responsible for the plasma membrane expression of PD-L1 in human uterine cervical SCC.
