Research progress on the mechanism of common inflammatory pathways in the pathogenesis and development of lymphoma.

In recent years, the incidence and mortality rates of lymphoma have gradually increased worldwide. Tumorigenesis and drug resistance are closely related to intracellular inflammatory pathways in lymphoma. Therefore, understanding the biological role of inflammatory pathways and their abnormal activation in relation to the development of lymphoma and their selective modulation may open new avenues for targeted therapy of lymphoma.

SOX10 promotes the malignant biological behavior of basal-like breast cancer cells by regulating EMT process.

Background: The diagnostic utility of SRY-box transcription factor 10 (SOX10) expression in basal-like breast cancer (BLBC) has been reported previously. However, the effect of SOX10 on the malignancy of BLBC cells and the underlying molecular mechanisms remain unelucidated. Here, we investigate the regulatory mechanisms and roles of SOX10 in BLBC progression.

Landscape of costimulatory molecule signature in breast cancer and its prognostic significance.

Background: Breast cancer (BRCA) is the most common malignant tumor in the world. Because of its substantial heterogeneity, its clinical treatment is faced with various problems. Only a small number of patients can benefit from the treatment of immune checkpoint inhibitor (ICI).

XCHD Inhibits C6 Cell Growth Primarily via the p53/Caspase Pathway.

The effects of XCHD on the proliferation of C6 cells and on factors associated with the microRNA-34a (miR-34a)/p53/caspase-3 signaling pathway were investigated. . XCHD was purchased too much to complete the study.

Transcriptome profiling revealed multiple genes and ECM-receptor interaction pathways that may be associated with breast cancer.

Background: Exploration of the genes with abnormal expression during the development of breast cancer is essential to provide a deeper understanding of the mechanisms involved. Transcriptome sequencing and bioinformatics analysis of invasive ductal carcinoma and paracancerous tissues from the same patient were performed to identify the key genes and signaling pathways related to breast cancer development.

Methods: Samples of breast tumor tissue and paracancerous breast tissue were obtained from 6 patients.

Transcriptome sequencing profiles reveal lncRNAs may involve in breast cancer (ER/PR positive type) by interaction with RAS associated genes.

To reveal novel lncRNAs and explore how could lncRNA affect the ER/PR positive type breast cancer, 16 different lncRNA transcriptomes (8 breast cancer tissues and 8 normal breast tissues) were successfully sequenced. In total, 8,954 high quality lncRNAs, including 5,516 lncRNAs reported in the previous studies and 3,438 novel lncRNAs, were annotated. The highest expressed lncRNAs were MALAT1, SCARNA10, RP11-206M11.

Roles of Signaling Pathways in the Epithelial-Mesenchymal Transition in Cancer.

The epithelial-mesenchymal transition (EMT) is a cellular process though which an epithelial phenotype can be converted into a phenotype of mesenchymal cells. Under physiological conditions EMT is important for embryogenesis, organ development, wound repair and tissue remodeling. However, EMT may also be activated under pathologic conditions, especially in carcinogenesis and metastatic progression.

[Investigation of the arsenic levels in ecosystem aspect in water type of endemic arsenicosis area in Datong City].

Objective: To investigate the arsenic levels in endemic arsenism in Datong City, Shanxi Province.

Methods: A total of 85 inhabitants from one village in endemic arsenism area in Datong City, Shanxi Province were collected as research subjects. The People's Republic of China health industry standard for endemic arsenism was used to identify and diagnosis the patients.

Transforming growth factor-β1 regulates epithelial-mesenchymal transition in association with cancer stem-like cells in a breast cancer cell line.

Epithelial-mesenchymal transition (EMT) is associated with altered connection and junctions between cells and changes in abilities of invasion and migration. In this study, we investigated whether SK-BR-3 breast cancer cells induced to undergo EMT exhibit changes in morphological and invasion abilities after Transforming growth factor β1 (TGF-β1) treatment. Serum-deprived SK-BR-3 cells were treated with TGF-β1 (0, 10 ng/mL) for 24 h.

Clinicopathological significance of PTEN and PI3K/AKT signal transduction pathway in non-small cell lung cancer.

A high frequency of mutations at the PTEN locus has been noticed in carcinoma of lung. However, the role of PTEN alternations and its association with outcome variables in the genesis of lung carcinoma are not understood fully. The purpose of our study was to examine the impact of EGFR, TGF-α, P-AKT and PTEN in the genesis of non-small cell lung cancer (NSCLC).

Oxidative DNA damage of peripheral blood polymorphonuclear leukocytes, selectively induced by chronic arsenic exposure, is associated with extent of arsenic-related skin lesions.

There is increasing evidence that oxidative stress is an important risk factor for arsenic-related diseases. Peripheral blood leukocytes constitute an important defense against microorganisms or pathogens, while the research on the impact of chronic arsenic exposure on peripheral blood leukocytes is much more limited, especially at low level arsenic exposure. The purpose of the present study was to explore whether chronic arsenic exposure affects oxidative stress of peripheral blood leukocytes and possible linkages between oxidative stress and arsenic-induced skin lesions.

Isolation and characterization of the full coding sequence of a novel densovirus from the mosquito Culex pipiens pallens.

During an investigation of arboviruses in China, a novel densovirus (DNV) was isolated from the adult female Culex pipiens pallens. The virus, designated Culex pipiens pallens densovirus (CppDNV), caused cytopathic effect in C6/36 cells. The virus particles were icosahedral, non-enveloped and had a mean diameter of 24 nm.
