Moreover, we highlighted utilization of miR-200 family as molecular biomarkers for early diagnosis, prognostic monitoring and appropriate therapy in hepatocellular carcinoma.

Circulating tumor cells (CTCs) are known as the root of cancer metastasis. Capture and inhibition of CTCs may prevent metastasis. Due to the rarity of CTCs in vivo, the current technology about CTCs capture is still challenging. The aim of our study was to conjugate the enhanced biostable double-strand (ds) circular aptamer (dApR) with dendrimers for capturing and restraining CTCs in vitro and in vivo.

CEM-targeting aptamer (Ap) was looped by ligation after phosphorylation to form circular ds aptamer dApR, which was then conjugated to dendrimers by biotin-streptavidin affinity reaction and named as G-dApR. The physicochemical properties of G-dApR were characterized by using PAGE gel electrophoresis, UV, DLS, AFM, fluorophotometer and laser confocal microscope. Biostability of G-dApR was also analyzed by gel electrophoresis. Confocal microscopy and flow cytometry were then performed to determine the binding specificity of G-dApR to CEM cells and the captured CTCs in mice and in human blood. Apoptosis of thand restrain CTCs in vitro and in vivo for preventing CTC-mediated cancer metastasis.

Pancreatic cancer is one of the most lethal malignancies. Accumulating evidence supports for the critical contribution of long noncoding RNAs (lncRNAs) to the cancer development and progression. We tried to identify novel lncRNAs involved in the pancreatic carcinogenesis.

Two independent datasets (Gene Expression Omnibus datasets GSE16515 and GSE32688) were obtained from the Gene Expression Omnibus (GEO). The level of BC037916 was detected in pancreatic cancer tissues and adjacent no-tumorous tissues (n=86) by qRT-PCR. Effects of BC037916 on proliferation, apoptosis, and invasion of pancreatic cancer cells were examined.

We identified a novel lncRNA BC037916 involved in the pancreatic carcinogenesis by analyzing GEO datasets. Quantitative RT-PCR analysis showed that 86.0% (74/86) pancreatic cancer tissues had increased BC037916 expression as compared with normal counterparts. Further, positive correlation was observed between BC037916 expression and clinical stage, primary tumor, and regional lymph node invasion. Importantly, BC037916 was an independent prognostic factor of pancreatic cancer. Functionally, knockdown of BC037916 repressed cell proliferation, inhibited cell invasion, halted cell cycle progression, and promoted apoptosis in both PANC-1 and SW1990 cells. In contrast, overexpression of BC037916 in CAPAN-1 had opposite effects. Moreover, silencing of BC037916 significantly inhibited the tumor growth of xenografted SW1990 cells in vivo. Results of Western blot assays suggested that BC037916 knockdown also suppressed the activation of JAK2/STAT3 and TGF-β signaling. Further experiments suggested that BC037916 positively regulated the expression of Twist through miR-3145-3p.

BC037916 exhibited oncogenic potential in pancreatic cancer development.

The incidence and mortality rates of lung cancer rank top in the different types of cancers in China. Licochalcone A (LA) is a flavonoid extracted from the roots of licorice with antitumor effects in various cancers

and

. However, the role of LA in non-small cell lung cancer (NSCLC) remains largely unclear.

The cell viability was measured by MTT assay, Edu staining and colony formation assay. Apoptosis was investigated using Annexin V/PI double-stained assays with flow cytometry. Real-time quantitative RT-PCR was carried out to investigate the expression of mRNA of related proteins. Western blotting was used to investigate the expression of related proteins.

The results show that LA inhibits the proliferation of NSCLC cells in a dose-dependent manner and induces apoptotic cell death. Moreover, LA significantly suppresses the expression of c-IAP1, c-IAP2, XIAP, Survivin, c-FLIP

and RIP1 without influencing the level of mRNA. https://www.selleckchem.com/products/muramyl-dipeptide.html Cycloheximide chase assay demonstrates that LA greatly decreases the stability of Survivin, XIAP and RIP1. Mechanistic studies indicate that LA induces cytoprotective autophagy since block of autophagy with CQ greatly enhances LA-induced anticancer activities. Furthermore, LA rapidly induces ERK and p38 activation in a time-dependent manner in both A549 and H460 cells, but suppresses the activities of c-Jun N-terminal kinase (JNK); suppression of ERK not p38 with inhibitor attenuates LA-induced autophagy, while it remarkably enhances LA-induced cytotoxicity in lung cancer cells and further promotes the degradation of apoptosis-related proteins.

The results of this study provide novel insights on the role of apoptosis-related proteins and the MAPKs pathway in the anticancer activities of LA.

To utilize liquid biopsy to investigate the potential clinical factors influencing the incidence of the acquired epidermal growth factor receptor (

) T790M mutation, and the impact of

circulating cell-free DNA (CfDNA) on overall survival for patients with advanced

mutated adenocarcinoma resistant to first-line EGFR-tyrosine kinase inhibitor (TKI).

A retrospective study was conducted to analyze

-mutated stage IIIB-IV adenocarcinoma patients who received an EGFR-TKI (gefitinib, erlotinib, or afatinib) as first-line therapy and then underwent a liquid biopsy exam at disease progression.

A total of 135 patients were included, and the T790M mutation was detected in 51 patients (37.7%). The incidence of T790M mutation increased with the number of initial metastatic sites (

= 0.015). Liver metastasis (odds ratio [OR], 3.373;

= 0.017) and other metastasis (OR, 3.063;

= 0.023) were also independently correlated with T790M mutation incidence. T790M mutation was also associated with more than two p having EGFR CfDNA, being positive for Del19/L858R mutations, and being positive for T790M mutation have differing impacts on overall survival for patients with advanced EGFR-mutated adenocarcinoma resistant to first-line EGFR-TKI.
