NADPH oxidase 4 facilitates progression of chondrosarcoma via generation of reactive oxygen species
Acta Biochim Pol. 2023 Sep 18. doi: 10.18388/abp.2020_6580. Online ahead of print.ABSTRACTNicotinamide adenine dinucleotide phosphate oxidase 4 (NOX4) is an enzyme that regulates reactive oxygen species (ROS) generation, and its function in the development of chondrosarcoma remains unclear. In the present study, we studied NOX4 expression in chondrosarcoma by immunochemical examination, and analyzed the role of NOX4 in viability and apoptosis of human chondrosarcoma cell line SW1353 using NOX4 siRNA or NOX4 inhibitor GKT137831. NOX4 level significantly increased in tumor compared to that in para-carcinoma sample. The level...

GSE242834 Gene expression profiling and the effect of HDAC9 in cisplatin resistance of esophageal squamous cell carcinoma
Series Type : Non-coding RNA profiling by arrayOrganism : Homo sapiensEsophageal cancer is one of the most serious health problems globally because of its high incidence and mortality rate. Cisplatin(CDDP) is the primary treatment but limited by the drug resistance. However, the mechanism of cisplatin resistance remains unclear. Herein, the CDDP-resistant cell line TE-1/CDDP was established to compared with TE-1, the expression profiles of circRNAs were compared between TE-1/CDDP and TE-1 using microarray analysis, Histone deacetylase 9(HDAC9) was identified significantly up-regulated. Using siRNA and conducting cell funct...

Crosstalk between PD-L1 and Jak2-Stat3/ MAPK-AP1 signaling promotes oral cancer progression, invasion and therapy resistance
CONCLUSIONS: PD-L1 was regulated mainly by the Jak2-Stat3/ MAPK-AP1 pathway, and besides the routine immunological functions, it supports OSCC survival, invasion, and therapy resistance. PD-L1 can be used as an indicator of severity and can be targeted along with Jak2-Stat3/ MAPK-AP1 for a better outcome OSCC.PMID:37678027 | DOI:10.1016/j.intimp.2023.110894

RNF149 confers cisplatin resistance in esophageal squamous cell carcinoma via destabilization of PHLPP2 and activating PI3K/AKT signalling
AbstractChemo-resistance has been identified as a crucial factor contributing to tumor recurrence and a leading cause of worse prognosis in patients with ESCC. Therefore, unravel the critical regulators and effective strategies to overcome drug resistance will have a significant clinical impact on the disease. In our study we found that RNF149 was upregulated in ESCC and high RNF149 expression was associated with poor prognosis with ESCC patients. Functionally, we have demonstrated that overexpression of RNF149 confers CDDP resistance to ESCC; however, inhibition of RNF149 reversed this phenomenon both in vitro and in vivo...

GSE197092 RNAseq analysis of genes differentially expressed in SMMC7721 cells with SNRPE knockdown
Contributors : Qipeng Wu ; Zhenzhou Jiang ; Luyong ZhangSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensHepatocellular carcinoma (HCC) is a malignant tumor with poor prognosis and lack of effective treatment targets is the major challenge in treating HCC. Previous studies have revealed significant changes in spliceosome-related genes in HCC. The unique expression pattern in tumor cells makes oncofetal proteins ideal candidate targets for cancer diagnosis and treatment. Therefore, we focused on the differentially expressed splicing factors in embryonic liver development and HCC. We ide...

Toll-interacting protein may affect doxorubicin resistance in hepatocellular carcinoma cell lines
CONCLUSIONS: Our results showed for the first time that silencing TOLLIP in hepatocellular carcinoma cells may help sensitize these cells to doxorubicin and increase the efficacy of chemotherapeutic regimens where doxorubicin is used.PMID:37644370 | DOI:10.1007/s11033-023-08737-2

Pyrrolidinedione-thiazolidinone hybrid molecules with potent cytotoxic effect in squamous cell carcinoma SCC-15 cells
This study aimed to investigate the cytotoxic effect of three derivatives 1-(4-hydroxyphenyl)-, 1-(4-chlorophenyl)- and 1-(4-bromophenyl)-3-[5-[2-chloro-3-(4-nitrophenyl)prop-2-enylidene]-4-oxo-2-thioxothiazolidine-3-yl]pyrrolidine-2,5-diones (Les-6287, Les-6294, and Les-6328, respectively), their effect on the production of the reactive oxygen species (ROS), apoptosis induction, and expression of genes - PPARγ, AHR, and NRFL2 - whose products are important in metabolism in human tongue squamous cell carcinoma cells of SCC-15 line. The results of resazurin reduction and lactate dehydrogenase (LDH) release assays proved th...
