How the secrets behind photocurrents are revealed in Ag-TiO heterostructures-based plasmonic photoelectrochemical systems: A collaborative approach of EC-SERS and photoelectrochemical methods.

Plasmon-mediated chemical reactions (PMCR) have garnered growing interest as a promising concept for photocatalysis. However, in electrochemical systems at solid-liquid interfaces, the photo-induced charge transfer on the surface of metal-semiconductor heterostructures involves complex processes and mechanisms, which are still poorly understood. We explore the plasmon-mediated carrier transfer mechanism and the synergistic effect of light and electric fields on Ag-TiO heterostructures, through a combination of electrochemical surface-enhanced Raman spectroscopy and photoelectrochemical methods, with para-aminothiophenol (PATP) serving as a probe molecule.

Analysis of the miRNA expression profile of laboratory red crucian carp under low-dose caesium-137 irradiation.

Radiation can cause the differential expression of biological miRNA molecules. This research was based on the development of the laboratory red crucian carp (LRCC) to explore the feasibility of its application in the detection of low-dose ionizing radiation-induced biological damage in aquatic environments and the development of related molecular markers. Adult LRCC were irradiated with caesium-137 at 0.

Holliday Cross-Recognition Protein : Association With the Tumor Microenvironment in Hepatocellular Carcinoma and With Patient Prognosis.

Hepatocellular carcinoma is the most common type of primary liver cancer, and it is associated with poor prognosis. It often fails to respond to immunotherapy, highlighting the need to identify genes that are associated with the tumor microenvironment and may be good therapeutic targets. We and others have shown that the Holliday cross-recognition protein can promote the proliferation, migration, and invasion by hepatocellular carcinoma cells, and that overexpression is associated with poor survival.

Prognostic value of PD -L1 expression in patients with primary solid tumors.

Programmed death-ligand 1 (PD-L1) is thought to play a critical role in immune escape by cancer, but whether PD-L1 expression can influence prognosis of patients with solid tumors is controversial. Therefore, we meta-analyzed available data on whether PD-L1 expression correlates with overall survival (OS) in such patients. PubMed, EMBASE and other databases were systematically searched for cohort or case-control studies examining the possible correlation between PD-L1 expression and OS of patients with solid tumors.

Apogossypolone, a small-molecule inhibitor of Bcl-2, induces radiosensitization of nasopharyngeal carcinoma cells by stimulating autophagy.

Nasopharyngeal carcinoma (NPC) is a major cause of cancer deaths. Concurrent administration of radiation and chemotherapy is the treatment of choice for advanced NPC. Previously, we showed that apogossypolone (ApoG2) induced apoptosis by blocking the binding of Bcl-2 to Bax, arresting the cell cycle in the S phase, in turn inhibiting proliferation of NPC cells both in vitro and in vivo.

Clinical efficacy of bevacizumab concomitant with pemetrexed in patients with advanced non-small cell lung cancer.

Objective: To observe the clinical efficacy of bevacizumab concomitant with pemetrexed in patients with advanced non-small cell lung cancer (NSCLC).

Materials And Methods: A total of 72 patients were randomly divided into a combination group (pemetrexed+bevacizumab, n=36) and a pemetrexed group (n=36) and assessed for disease control (CR+PR+SD) after 4-cycles of first-line GP chemotherapy (gemcitabine+cisplatin). Clinical efficacy, progression-free survival time (PFS), overall survival time (OS), overall response rate (ORR), disease control rate (DCR) and rate of adverse responses between two groups were observed and compared.

Harmine induces apoptosis in HepG2 cells via mitochondrial signaling pathway.

Background: Harmine has antitumor and antinociceptive effects, and inhibits human DNA topoisomerase. However, no detailed data are available on the mechanisms of action of harmine in hepatocellular carcinoma. This study aimed to investigate the effects of harmine on proliferation and apoptosis, and the underlying mechanisms in the human hepatocellular carcinoma cell line HepG2.

Sodium valproate induces mitochondria-dependent apoptosis in human hepatoblastoma cells.

Background: Sodium valproate inhibits proliferation in neuroblastoma and glioma cells, and inhibits proliferation and induces apoptosis in hepatoblastoma cells. Information describing the molecular pathways of the antitumor effects of sodium valproate is limited; therefore, we explored the mechanisms of action of sodium valproate in the human hepatoblastoma cell line, HepG2.

Methods: The effects of sodium valproate on the proliferation of HepG2 cells were evaluated by the Walsh-schema transform and colony formation assays.

[Knock-down of apollon gene by antisense oligodeoxynucleotide inhibits the proliferation of Lovo cells and enhances chemo-sensitivity].

In this study, the effects of apollon antisense oligodeoxynucleotide (ASODN) on the proliferation and apoptosis of human Lovo cells in vitro were investigated. Apollon ASODN was incubated with human colorectal Lovo cells for 48 h, the proliferation inhibition and the clone forming rates were detected by WST method and clone formation assay, respectively. The expression of apollon mRNA was analyzed by real time fluorescent quantitative reverse transcription polymerase chain reaction.
