Phosphoglycerate mutase 1(PGAM1) promotes pancreatic ductal adenocarcinoma (PDAC) metastasis by acting as a novel downstream target of PI3K/Akt/mTOR pathway.
This study indicates that PGAM1 is closely associated with clinical metastasis and poor prognosis of PDAC. PGAM1 is considered as a potential therapeutic target in PDAC metastasis. PMID: 29386088 [PubMed - as supplied by publisher]

MicroRNA-664 targets Insulin receptor substrate 1 to suppress cell proliferation and invasion in breast cancer.
This study showed that miR-664 expression was obviously reduced in BC tissues and cell lines. Resumption expression of miR-664 attenuated the proliferation and invasion of BC cells. The molecular mechanism underlying the inhibitory effects of BC cell proliferation and invasion by miR-664 was also studied. Insulin receptor substrate 1 (IRS1) was identified as a novel and direct target of miR-664. In addition, siRNA-mediated silencing of IRS1 expression mimicked the suppressive effects of miR-664 overexpression in BC cells. Rescue experiments demonstrated that recovered IRS1 expression partially antagonized the inhibition of...

NOTCH3 overexpression and post-transcriptional regulation by miR-150 were associated with EGFR-TKI resistance in lung adenocarcinoma.
Authors: Zhang Y, Chen B, Wang Y, Zhao Q, Wu W, Zhang P, Miao L, Sun S Abstract Acquired resistance remains a key challenge in epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKI) therapy in lung adenocarcinoma (LUAD). Recent studies have shown that Notch signaling is associated with drug resistance. However, its role and possible mechanisms in EGFR-TKI resistance are not yet clear. In our study, we found that among 4 members of NOTCH1-4, only NOTCH3 was up-regulated in LUAD tissues and TKI-resistant cell line (HCC827GR6). Knockdown of NOTCH3 by siRNA significantly inhibited proliferative abilit...

miR-203 inhibits the invasion and EMT of gastric cancer cells by directly targeting Annexin A4.
Authors: Li J, Zhang B, Cui J, Liang Z, Liu K Abstract Many studies have shown that down-regulated miR-203 level is in a variety of cancers including gastric cancer (GC). However, the precise molecule mechanisms of miR-203 in GC have not been well clarified. In current study, we investigated the biological functions and molecular mechanisms of miR-203 in GC cell lines. We found that miR-203 is down-regulated in GC tissues and cell lines. Moreover, the low level of miR-203 was associated with increased expression of Annexin A4 in GC tissues and cell lines. The invasion and EMT of GC cells was suppressed by overexpre...

Inhibition of proliferation by knockdown of transmembrane (TMEM) 168 in glioblastoma cells via suppression of Wnt/beta-catenin pathway.
Authors: Xu J, Su Z, Ding Q, Shen L, Nie X, Pan X, Yan A, Yan R, Zhou Y, Li L, Lu B Abstract Human glioblastoma multiforme (GBM) accounts for the majority of human brain gliomas. Several TMEM proteins, such as TMEM 45A, TMEM 97, and TMEM 140, are implicated in human brain gliomas. However, the roles of TMEM168 in human GBM remained extremely poor. Herein, we found that mRNA levels of TMEM168 were overexpressed in GBM patients (n = 85) when compared with healthy people (n = 10), which was also supported by data from The Cancer Genome Atlas (TCGA). KaplanMeier analysis of Gene Expression Omnibus dataset GSE16011 sugg...

EIF5A2 is highly expressed in anaplastic thyroid carcinoma and is associated with tumor growth by modulating TGF- β signals.
EIF5A2 is highly expressed in anaplastic thyroid carcinoma and is associated with tumor growth by modulating TGF-β signals. Oncol Res. 2020 Mar 05;: Authors: Huang Y, Zhu Q, Lu L, Sun S, Hao F, Zhang J, Liu Z, Miao Y, Jiao X, Chen D Abstract Anaplastic thyroid carcinoma (ATC) are resistant to standard therapies and has no effective treatment. Eukaryotic translation initiation factor 5A2 (EIF5A2) has shown to be upregulated inmany malignant tumors and proposed to be a critical gene involved in tumor metastasis. In thisstudy, we aim to investigate the expression status of EIF5A2 in human ATC tissues, an...

Suppression of human papillomavirus type 16 E5 oncoprotein: A promising step in fostering the treatment of cervical cancer
In this study, we used E5-siRNA to knockdown that essential oncogene and considered the effect of E5 silencing on proliferation, apoptosis, cell cycle, apoptosis-related gene expression, and the initiator of the EGFR signaling pathway in cervical cancer cells. The results demonstrate that E5 plays an essential role in the proliferation and inhibited apoptosis in cervical cancer. Furthermore, silencing E5 reduces proliferation, increases apoptosis, and elevates related-genes expression of these malignant cells. Overall, E5 suppression may be appropriate for ameliorating cervical cancer progression.PMID:37305401 | PMC:PMC102...
