Hyperactivated glucose uptake and glycolytic metabolism are considered as a hallmark of cancer. Berberine, a natural alkaloid with tumor‑selective anticancer effects, has been shown to promote glucose uptake in metabolic tissues and cells. However, whether and how berberine regulates the glucose metabolism of cancer cells are still poorly understood. In the present study, we revealed that berberine, which suppressed the growth of colon cancer cell lines HCT116 and KM12C, greatly inhibited the glucose uptake and the transcription of glucose metabolic genes, GLUT1, LDHA and HK2 in these two cell lines as assessed by RT‑qPCR...

Circulating tumour cell (CTC) behaviours are distinct from those of bulk tissues. Thus, treatments to eliminate CTCs differ from the regimens followed to reduce the primary tumour and its metastases. Accordingly, comprehensively deciphering the single nucleotide variant (SNV) profiles in CTCs, which partially determine CTC behaviours, is a priority. Using viable CTCs isolated with the oHSV1‑hTERT‑GFP virus coupled with fluorescence‑activated cell sorting (FACS), the whole genome was amplified using the multiple annealing and looping‑based amplification cycle (MALBAC) method...

FAT atypical cadherin 1 (FAT1) belongs to the cadherin superfamily and has been reported to regulate cell‑cell adhesion and other cell behaviors, suggesting its pivotal roles in human cancers. We previously identified FAT1 as one of the significant mutant genes in esophageal squamous cell carcinoma (ESCC). In the present study, the knockdown of FAT1 expression in YSE2 and Colo680N cell lines was carried out by lentivirus, and we found that knockdown of FAT1 led to acceleration of cell migration and invasion...

The objective of this study was to identify potentially significant genes and long non-coding RNAs (lncRNAs) in colon cancer for a panel of lncRNA signatures that could be used as prognostic markers for colon adenocarcinoma (COAD) based on the data from The Cancer Genome Atlas (TCGA). RNA-seq V2 exon data of COAD were downloaded from the TCGA data portal for 285 tumor samples and 41 normal tissue samples adjacent to tumors. Differentially expressed mRNAs and lncRNAs were identified. A functional enrichment analysis of differentially expressed mRNAs was performed, followed by protein-protein interaction (PPI) network construction and significant module selection...

Bone remodeling can be interrupted by tumor cells which leads to an inappropriate balance of osteoblasts and osteoclasts. As the progenitors of osteoblasts, mesenchymal stem cells (MSCs) have been reported to exhibit an abnormal osteogenic differentiation potential in some cancer‑related bone lesions. However, the evidence is very limited in terms of the biological alterations of MSCs in the bone metastasis of non‑small cell lung cancers (NSCLC). We investigated the expression and function of miR‑139‑5p in MSC osteogenic differentiation in vitro in normal and NSCLC-exposed condition...

The ligand of CD40, known as CD154 or CD40L, is the key to immunostimulatory and anticancer activity, but how CD40L affects cellular senescence is unclear. Thus, we studied a membrane‑stable mutant form CD40L (CD40L‑M) to explore tumor growth and cellular senescence in CD40‑positive NSCLC cells. We found that CD40L‑M‑expressing cells had senescent characteristics, including reduced cell proliferation and enlargement, increased SA‑β‑gal staining activity, and overexpression of several cell cycle regulators p53 and p21...

Anti-angiogenesis is one of the most general clinical obstacles in cancer chemotherapy. Kaempferol is a flavonoid phytochemical found in many fruits and vegetables. Our previous study revealed that kaempferol triggered apoptosis in human umbilical vein endothelial cells (HUVECs) by ROS‑mediated p53/ATM/death receptor signaling. However, the anti‑angiogenic potential of kaempferol remains unclear and its underlying mechanism warranted further exploration in VEGF‑stimulated HUVECs. In the present study, kaempferol significantly reduced VEGF‑stimulated HUVEC viability...

The complexation of lysozyme with aggregates from two triblock amphiphilic polyelectrolytes of the same blocks but different topologies and block molar masses, namely PS-b-SCPI-b-PEO and SCPI-b-PS-b-PEO, is investigated by scattering and spectroscopy methods. Light scattering reveals that the interaction with lysozyme causes shrinkage of the self-assembled nanoparticles in the case of the hydrophobic-polyelectrolyte-hydrophilic sequence. In the polyelectrolyte-hydrophobic-hydrophilic sequence, the opposite trend is observed...

The maser-the microwave progenitor of the optical laser-has been confined to relative obscurity owing to its reliance on cryogenic refrigeration and high-vacuum systems. Despite this, it has found application in deep-space communications and radio astronomy owing to its unparalleled performance as a low-noise amplifier and oscillator. The recent demonstration of a room-temperature solid-state maser that utilizes polarized electron populations within the triplet states of photo-excited pentacene molecules in a p-terphenyl host paves the way for a new class of maser...
