GSE99422 KH-type splicing regulatory protein (KHSRP) is involved in esophageal squamous cell carcinoma progression through regulating a subset of microRNAs mRNA

Contributors : Yuji Fujita ; Kiyoshi Masuda ; Issei ImotoSeries Type : Expression profiling by arrayOrganism : Homo sapiensKH-type splicing regulatory protein (KHSRP) is a multifunctional RNA-binding protein (RBP), which is involved in many post-transcriptional aspects of RNA metabolism including microRNA (miRNA) biogenesis, affects distinct cell functions in different tissues and can impact on various pathological conditions. However, the function and underlying mechanisms of KHSRP in esophageal squamous cell carcinoma (ESCC) remain largely unknown. In the present study, we uncover a novel oncogenic function of KHSRP in esophageal tumorigenesis, and implicate its use as a marker for prognostic evaluation and as a putative therapeutic target in ESCC.

CONCLUSIONS TCF21 is downregulated in ESCC, and its low expression is closely correlated with N stage and predicts a poor prognosis. TCF21 functions as a tumor suppressor in ESCC progression, and enhancement of its expression levels may be partly through promoting Kiss-1 expression to reverse EMT by modulating EMT-related gene expression. Thus, TCF21 can potentially be used as a treatment target for ESCC. PMID: 29909422 [PubMed - in process]

In this study, we detected TNFR2 expression in ESCC tissues using IHC. The χ2 test showed that TNFR2 was positively correlated with invasion depth, advanced clinical stage and low differentiation; survival analysis showed that TNFR2 was positively correlated with poor OS; univariate Cox regression analysis showed that clinical stage, lymph node involvement and invasion de pth were all correlated with OS; multivariate Cox regression analysis showed that lymph node involvement and invasion depth were independent prognostic factors.

ConclusionDCF chemotherapy alone had a substantial therapeutic effect on SESCC in all cases. However, despite the normal appearance of the mucosal surface, viable cancer cells remained below the basal layer of mucosa. Careful attention should be paid when diagnosing clinical CR, or securing a resection margin of SESCC after DCF chemotherapy.

Conclusions: The results of the present study suggest that reductions in AE2 in ESCC enhance cellular movement by activating MMP signaling pathways and are related to a poor prognosis in patients with ESCC. Methods: In human ESCC cell lines, knockdown experiments were conducted using AE2 siRNA, and the effects on cellular movement and survival were analyzed. The gene expression profiles of cells were examined using a microarray analysis. An immunohistochemical analysis was performed on 61 primary tumor samples obtained from ESCC patients who underwent esophagectomy. PMID: 29899837 [PubMed]

ConclusionsDCF-R treatment for advanced cervical esophageal cancer could be completed by the careful administration; although a strong blood toxicity might occur, this treatment may provide the chance to obtain favorable prognosis with larynx preservation.

Esophageal cancer (EC) is the 6  t h leading cause of cancer mortality worldwide with poor prognosis, hence more effective chemotherapeutic drugs for this deadly disease are urgently needed. We previously reported that high expression of Orai1, a store-operated Ca2+entry (SOCE) channel was associated with poor survival rate in EC patients and Orai1-mediated intracellular Ca2+ oscillations regulated cancer cell proliferation. Previous studies suggested that Orai1-mediated SOCE is a promising target for EC chemotherapy.

Conclusions: ME-NBI provides a high diagnostic rate in evaluating the esophagus to diagnose squamous cell carcinoma. In the differentiation for invasion depth staging, ME-NBI was demonstrated to be superior to white light endoscopy and had a similar diagnostic rate compared with HF-EUS. However, HF-EUS had high positive likelihood values for invasion depth staging, suggesting that HF-EUS is a reliable method for confirming invasion depth staging. PMID: 29888281 [PubMed - in process]

Deferoxamine (DFO) was found to modulate multiple cellular pathways involved in the growth of breast cancer, hepatocellular carcinoma, lung cancer and bladder cancer. However, the effect of DFO on esophageal squamous cell carcinoma (ESCC) remains unclear. Here, we report that DFO-treated ESCC cells show strong anti-tumorigenic properties, such as inhibition of cell proliferation, induction of cell cycle arrest, and promotion of apoptosis. Mechanistically, DFO significantly activated ERK1/2 signaling, which is reactive oxygen species (ROS)-dependent.
