Neuropilin-1 (NRP1) binds to many ligands and co-receptors and affects cell survival and migration, which is essential for tumor progression. However, there are still largely unknowns about how NRP1 affects the epithelial-mesenchymal transition (EMT)-related malignant progression in gastric cancer.

We used TCGA to analyze the expression of NRP1 in gastric cancer and its impact on patient survival. In in vitro experiments, transwell, wound healing and colony formation assays were used to evaluate the effects of NRP1 and ginsenoside Rg3 on the invasion, migration and proliferation of gastric cancer cells. In in vivo experiments, we evaluated the overexpression and knockdown of NRP1 and the effect of ginsenoside Rg3 on tumor growth.

We found that NRP1 is highly expressed in advanced gastric cancer and associated with poor prognosis. Knockdown of NRP1 expression can inhibit the proliferation and metastasis of gastric cancer cells. Mechanically. NRP1 interacts with fibronectin-1 (FN1) to promote the malignant progression of gastric cancer cells through ECM remodeling. In addition, we found that ginsenoside Rg3 can block the interaction of NRP1 and FN1 and inhibit the progression of gastric cancer.

Our study suggested that the interaction of NRP1 and FN1 is crucial for the malignant progression of gastric cancer. This may provide a new perspective and potential treatment methods for the treatment of gastric cancer.

Many studies found that VPS53, one of the subunits of the golgi-associated retrograde protein (GARP) complexes, was aberrantly expressed in human diseases.

This study investigated the functions and molecular mechanisms of VPS53 in colorectal cancer (CRC).

Expression and correlation of Beclin 1 and VPS53 were analyzed by RT-qPCR and Pearson's correlation in CRC tissues, and VPS53 expression was also determined in CRC cells. Selleck Estrone The changes of proliferation, migration, invasion, apoptosis, and autophagy of CRC cells were examined by a succession of functional experiments including CCK-8, flow cytometry, transwell assay, and electron microscopy. The levels of autophagy related proteins were evaluated by Western blotting analysis.

RT-qPCR results found that VPS53 was downregulated in CRC tissues and cells, and Beclin 1 expression was also decreased in CRC tissues. There was a positive correlation between VPS53 and Beclin 1. Functional results showed that overexpression of VPS53 could suppress proliferation, migration, and invasion, and accelerate apoptosis and autophagy of CRC cells. Also, VPS53 could upregulate Beclin 1 and LC3BII, suggesting the inductive effect of VPS53 on CRC cell autophagy. Furthermore, it was found that the autophagy inhibitor (Inhb) could attenuate the inhibition of VPS53 on CRC progression.

VPS53 repressed CRC progression by regulating the autophagy signaling pathway, suggesting that VPS53 might be a promising therapeutic target for CRC.

Tobacco smoking is the most predominant etiology for lung cancer. However, only a small percentage of heavy smokers develop lung cancer, which suggests that other cofactors are required for lung carcinogenesis. Viruses have been central to modern cancer research and provide profound insights into cancer causes. Nevertheless, the role of virus in lung cancer is still unclear. In this article, we reviewed the possible oncogenic viruses associated with lung cancer.
Long noncoding RNA (lncRNA) have proved to be important regulators in various diseases. CDKN2B-AS1 was a newly identified tumor-related lncRNA, and previous studies have reported its function in laryngeal squamous cancer and osteosarcoma. However, the function and mechanism of lncRNA CDKN2B-AS1 in lung cancer are still unknown.

Cell proliferation, invasion, migration and apoptosis were detected via CCK-8, transwell assay and Western blot. Bioinformatics analysis was used to predict the potential target of CDKN2B-AS1. A rescue experiment was performed to identify the relationship between CDKN2B-AS1 and miR-378b.

The expression of lncRNA CDKN2B-AS1 was significantly upregulated in lung cancer tissues and cell lines. Overexpression of CDKN2B-AS1 promoted cell proliferation, invasion and reduced cell apoptosis. Knockdown of CDKN2B-AS1 inhibited cell proliferation, invasion and increased cell apoptosis. Bioinformatics analysis predicted that miR-378b was the direct target. We also provided evidence that NR2C2 was the target of miR-378b. The expression of NR2C2 was significantly upregulated in lung cancer tissues and cell lines. The rescue experiment further confirmed the relationship between CDKN2B-AS1 and miR-378b. Overexpression of miR-378b completely reversed the function of CDKN2B-AS1.

Taken together, our results comprehensively analyzed the function of CDKN2B-AS1 in lung cancer and provided a possible mechanism that CDKN2B-AS1 facilitates lung cancer development by regulating miR-378b and NR2C2. Thus, our study offers a potential therapeutic target for treating lung cancer.

Disulfiram (DSF), a drug used in the treatment of alcoholism since 1948, has been shown to have antitumor properties in various tumor types possibly due to the induction of a type cell death, ferroptosis, and the sensitization of cells to chemo- and radiotherapy. In this study, we explored the antitumor properties of DSF in glioblastoma (GBM) and investigated the underlying molecular mechanisms.

GBM cell lines U251 and LN229 were treated with DSF to assess cytotoxicity and activity of the molecule in vitro. Response of cells to treatment was examined using cell viability, flow cytometry, LDH release assay, immunofluorescence and Western blot analysis.

DSF inhibited cell growth of GBM U251 and LN229 cell lines in vitro in a concentration-dependent manner. Flow cytometry demonstrated that DSF caused G0-G1 growth arrest. DSF treatment led to increased ROS and lipid peroxidation levels relative to controls indicating the involvement of ferroptosis. Furthermore, DSF triggered lysosomal membrane permeabilization (LMP), a critical mechanism promoting cell death, in a ROS-dependent manner. Finally, DSF enhanced radiosensitivity of U251 and LN229 cells.

Our findings indicated that DSF induced ferroptosis and LMP and enhanced the radiosensitivity of GBM cells. Therefore, DSF might have efficient antitumor activity in the treatment of human GBM.

The aim of this study was to investigate the allelic relation between de novo T790M and concomitant sensitizing
mutations in EGFR-TKIs naïve NSCLCs and to explore whether the formalin-fixed and paraffin-embedded (FFPE) materials affect the detection of de novo EGFR T790M mutation.

Specimens of 300 consecutive EGFR-TKI naïve NSCLCs who received surgical resection between January 2016 and June 2018 were retrospectively investigated. All the snap-frozen tumor tissues from 300 NSCLCs were screened by droplet digital PCR (ddPCR) for the detection of de novo T790M mutation. The allelic relation between de novo T790M mutation and concomitant sensitizing
mutations was also investigated. Furthermore, we assessed de novo T790M mutation in paired FFPE specimens of 50 patients which included tumor tissues and paired normal lung tissues of the pretreatment NSCLCs to investigate whether FFPE materials affect the detection of de novo T790M mutation.

The de novo T790M mutation was observed in four patients which oncomitant sensitizing mutations for pretreatment NSCLCs. Analytical cut-off of ddPCR assay for FFPE specimens should be validated carefully considering the possibility of FFPE-derived artificial gene mutations.
Gastric cancer (GC) is one of the deadliest cancer worldwide. Multiple long non-coding RNAs (lncRNAs) are recently identified as crucial oncogenic factors or tumor suppressors in GC. In this study, we aimed to probe into the effect of LINC01436 on GC progression.

LINC01436 and miR-513a-5p expressions in GC tissue samples were measured using quantitative real-time polymerase chain reaction (qRT-PCR). Western blot was used to detect the expression of apurinic/apyrimidinic endodeoxyribonuclease 1 (APE1) expression. Human GC cell lines AGS and BGC-823 were employed to investigate the function and mechanism of LINC01436 in GC. Cell counting kit-8 (CCK-8) assay was used to assess the effect of LINC01436 on proliferation. Flow cytometry was utilized to explore the effect of LINC01436 on apoptosis, and Transwell assay was conducted to detect the effect of LINC01436 on the migration and invasion. Colony formation assay was performed to evaluate the effect of LINC01436 on radioresistance of GC cells. Furthermore, lecular sponge of tumor suppressor miR-513a-5p, which indirectly enhances the APE1 expression and functions as the oncogenic lncRNA in GC.
Glioblastoma (GBM) is the most commonly diagnosed primary brain tumor in adults. Despite a variety of advances in the understanding of GBM cancer biology during recent decades, very few of them were applied into treatment, and the survival rate of GBM patients has not been improved majorly due to the low chemosensitivity to temozolomide (TMZ) or low radiosensitivity. Therefore, it is urgent to elucidate mechanisms of TMZ- and IR-resistance and develop novel therapeutic strategies to improve GBM treatment.

TMZ- and IR-resistant cell lines were acquired by continuous exposing parental GBM cells to TMZ or IR for 3 months. Cell viability was determined by using Sulforhodamine B (SRB) assay. Protein and mRNA expression were examined by Western blotting assay and quantitative polymerase chain reaction (qPCR) assay, respectively. Homologous recombination (HR) and nonhomologous end joining (NHEJ) efficiency were measured by HR and NHEJ reporter assay. Cell apoptosis was determined by Caspase3/7 activity. Autophagy was analyzed using CYTO-ID
Autophagy detection kit. Tumor growth was examined by U87 xenograft mice model.

DNA repair efficiency of non-homologous end joining (NHEJ) pathway is significantly increased in TMZ- and IR-resistant GBM cells. Importantly, APLF, which is one of the DNA end processing factors in NHEJ, is upregulated in TMZ- and IR-resistant GBM cells and patients. APLF deficiency significantly decreases NHEJ efficiency and improves cell sensitivity to TMZ and IR both in vitro and in vivo.

Our study provides evidence for APLF serving as a promising, novel target in GBM chemo- and radio-therapy.
