ATF4/MYC Regulates MTHFD2 to Promote NSCLC Progression by Mediating Redox Homeostasis
CONCLUSIONS: ATF4 promoted high expression of MTHFD2 in NSCLC dependent on MYC.PMID:36051358 | PMC:PMC9425107 | DOI:10.1155/2022/7527996

Upregulation of dual-specificity phosphatase-26 is required for transforming growth factor β1(TGFβ1)-induced Epithelial-mesenchymal transition in A549 and PANC1 cells
CONCLUSIONS: Data provided suggest that TGFβ1 modulates the expression of DUSP genes and that upregulation of DUSP26 may be required for TGFβ1-promoted EMT in A549 and PANC1 cells. Further studies should be carried out to elucidate the requirement of individual DUSPs in TGFβ1-associated EMT in tumor cells.PMID:36053282 | DOI:10.1007/s11033-022-07893-1

GSE183178 Identification of Wnt target genes associated with malignant phenotypes in CTNNB1-mutated NSCLC
Contributors : Noriaki Sunaga ; Luc GirardSeries Type : Expression profiling by arrayOrganism : Homo sapiensMicroarray analysis comparing the expression profiles of siRNA-mediated CTNNB1-silenced and CTNNB1-retained HCC15 cells harboring a homozygous CTNNB1 S45F mutation revealed that besides several known Wnt genes, LGR6 was significantly downregulated by CTNNB1 knockdown in HCC15 cells.

Aspirin blocks AMPK/SIRT3-mediated glycolysis to inhibit NSCLC cell proliferation
Eur J Pharmacol. 2022 Aug 15:175208. doi: 10.1016/j.ejphar.2022.175208. Online ahead of print.ABSTRACTNon-small cell lung cancer (NSCLC) has the highest incidence and mortality in the world. Aspirin has been reported to promote apoptosis, inhibit proliferation, stemness, angiogenesis, cancer-associated inflammation and migration in NSCLC. But the effect of aspirin on aerobic glycolysis in NSCLC is less reported. In the present study, we investigated whether aspirin blocked aerobic glycolysis of NSCLC cell to inhibit proliferation. Our results showed that aspirin inhibited viability, PCNA expression, ability of colony forma...

RP11-79H23.3 Inhibits the Proliferation and Metastasis of Non-small-cell Lung Cancer Through Promoting miR-29c
Biochem Genet. 2022 Aug 16. doi: 10.1007/s10528-022-10263-y. Online ahead of print.ABSTRACTEvidences indicate that long non-coding RNAs (lncRNAs) are closely involved and contributed to tumorigenesis and cancer progression. As a novel lncRNA, RP11-79H23.3 was found to be an anti-oncogene in bladder cancer. However, the essential roles and functions of RP11-79H23.3 in non-small-cell lung cancer (NSCLC) remains to be elucidated. Here, loss of functional assay was applied to gain insights into the functions of RP11-79H23.3 on the proliferation and metastasis capabilities of A549 and H1299 cells. Meantime, Real-time PCR was ut...

Heat shock protein 90 inhibitor 17-AAG down-regulates thymidine phosphorylase expression and potentiates the cytotoxic effect of tamoxifen and erlotinib in human lung squamous carcinoma cells
Biochem Pharmacol. 2022 Aug 9:115207. doi: 10.1016/j.bcp.2022.115207. Online ahead of print.ABSTRACTElevated thymidine phosphorylase (TP) levels, a key enzyme in the pyrimidine nucleoside salvage pathway, in cancer cells, are related to a poor prognosis in a variety of cancers. Heat shock protein 90 (Hsp90) is a ubiquitous molecular chaperone that is involved in the stabilization and maturation of many oncogenic proteins. The aim of this study is to elucidate whether Hsp90 inhibitor 17-AAG could enhance tamoxifen- and erlotinib-induced cytotoxicity in nonsmall cell lung cancer (NSCLC) cells via modulating TP expression in ...

Overexpression of 14-3-3 ζ primes disease recurrence, metastasis and resistance to chemotherapy by inducing epithelial-mesenchymal transition in NSCLC
In this study, we found that overexpression of 14-3-3ζ was more frequent in NSCLC tumor tissues with tumor recurrence. By using scratch healing assay and transwell assay, we demonstrated that NSCLC cells with high expression of 14-3-3ζ gained increased motile and invasive capacity, whereas siRNA-mediated knockdown of endogenous 14-3-3ζ abrogated cancer cell dissemination. Intriguingly, we found that NSCLC cells underwent epithelial-mesenchymal transition (EMT) after the induction of 14-3-3ζ in vitro and in vivo. These findings could be readily recaptured in clinical setting since we showed that NSCLC tumor specimen wit...

Targeting HER3-dependent activation of nuclear AKT improves radiotherapy of non-small celllung cancer
CONCLUSION: IR-induced activation of nuclear AKT occurs inside the nucleus that is mainly dependent on HER3 expression in NSCLC. These findings suggest that targeting HER3 in combination with radiotherapy may provide a logical treatment option for investigation in selected NSCLC patients.PMID:35839938 | DOI:10.1016/j.radonc.2022.07.008
