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...

The incidence of lung cancer in China increases annually, and effective targets for the diagnosis and treatment of lung cancer are urgently needed. miRNAs are currently considered to be involved in the regulation of tumor development and growth. miR‑24 has been found to contribute to the development of several tumors. Menin is a key tumor suppressor gene, and its expression is generally low in lung cancer. The effects of miR‑24 on the biological behavior of lung cancer cells were detected by MTT and Transwell assays...

Ring finger protein 2 (RNF2), also known as RING2 or RING1B, displays oncogenic functions in different types of cancers, yet, the function of RNF2 during mitosis has not been evaluated. A yeast two‑hybrid screen was undertaken using a human HeLa cDNA library to explore and identify proteins that interact with RNF2. Several positive clones, including Polo‑like kinase 1 (Plk1), a critical regulator of mitosis, were identified. The interaction between RNF2 and Plk1 was confirmed using a β‑galactosidase and growth test in selective media, in vitro glutathione S‑transferase pull‑down, and in vivo immunoprecipitation assays...

FoxO transcription factors are important regulators of cell survival in response to a variety of stress stimuli and play vital functions in tumor progression. However, the functions and underlying regulators of FoxO3a in colorectal cancer (CRC) have not been fully elucidated. The aim of the current study was to identify the functions of FoxO3a in CRC and characterize the transcription elements within the promoter region of FoxO3a. The expression of FoxO3a was upregulated in response to hypoxic and oxidative stress stimuli...

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...

Carcinoma‑associated fibroblasts (CAFs) are the major components of mesenchymal cells in the inflammatory tumor microenvironment. They are involved in epithelial‑mesenchymal transition (EMT) and chemotherapy resistance by directly contacting with cancer cells or secretory cytokines. In the present study, we examined the role of CAFs in the induction of EMT in ovarian cancer. Primary ovarian cancer cells, CAFs and normal fibroblasts (NFs) were isolated from fresh cancer tissue and cultured for immunohistochemistry studies...

Triple-negative breast cancer (TNBC) and malignant melanoma are highly aggressive cancers that widely express the cell surface chondroitin sulfate proteoglycan 4 (CSPG4/NG2). CSPG4 plays an important role in tumor cell growth and survival and promotes chemo- and radiotherapy resistance, suggesting that CSPG4 is an attractive target in cancer therapy. In the present work, we applied the drug delivery technology photochemical internalization (PCI) in combination with the novel CSPG4-targeting immunotoxin 225...

Localized separation of strands of duplex DNA is a necessary step in many DNA-dependent processes, including transcription and replication. Little is known about how these strand separations occur. The strand-separated E.coli RNA polymerase-promoter open-complex structure showed four bases of the non-template strand, the master base -11A, -7, -6 and +2, in a flipped state and inserted into protein pockets. To explore whether any property of these bases in the duplex state pre-disposes them to flipping, NMR studies were performed on a wild-type promoter in the duplex state...

Planar super-oscillation lenses (SOLs) can fulfill super-resolution focusing and nanoscopic imaging in the far field without the contribution of evanescent waves. Nevertheless, the existing deviations between the design and experimental results have been seldomly investigated, leaving the practical applications of SOLs unpredictable and uncontrollable. In this paper, some application-oriented issues are taken into consideration, such as the inevitable fabrication errors and the size effect of the designed SOLs, with the aim of providing an engineering reference to elaborately customize the demanded focusing light field...
