Artemisinin ameliorates thyroid function and complications in adult male hypothyroid rats via upregulation of the L1 cell adhesion molecule.

Background: Hypothyroidism, a common worldwide syndrome caused by insufficient thyroid hormone secretion, affects number of people at different ages. Artemisinin (ART), a well-known effective agent in the treatment of malaria, also has anti-oxidative stress functions in various diseases. The L1 cell adhesion molecule exerts multiple protective roles in diseased systems.

Efficacy of roxadustat in maintenance hemodialysis patients with erythropoietin-hyporesponsive anemia.

Objective: To investigate the efficacy of roxadustat in hemodialysis patients with erythropoietin (EPO) hypo-responsive anemia.

Materials And Methods: This retrospective study included 55 hemodialysis patients with erythropoietin hypo-responsive anemia at the First Affiliated Hospital of Chongqing Medical University from January to December 2020. We observed their hemoglobin (Hb) changes, inflammatory factors, and adverse reactions before and after 12 weeks of roxadustat treatment.

Analysis of the evolution trends and influential factors of bankfull discharge in the Lower Yellow River.

After the Xiaolangdi Reservoir (XLDR) was put into operation, new water and sediment conditions have improved the silting condition of the Lower Yellow River (LYR), but against this background, the flow capacity of the LYR has become more complex. In this research, the measured water and sediment data of seven hydrological stations in the LYR from 1950 to 2020 were systematically collated. The evolution trend and development period of the bankfull discharge in this area were studied based on the wavelet analysis method, and the main factors influencing the evolution of the bankfull discharge were explored.

Ambrosin sesquiterpene lactone exerts selective and potent anticancer effects in drug-resistant human breast cancer cells (MDA-MB-231) through mitochondrial mediated apoptosis, ROS generation and targeting Akt/β-Catenin signaling pathway.

Purpose: Breast cancer accounts for a significant proportion of cancer burden among women world over. Concerning breast cancer treatment, there are only few chemotherapeutic agents available, which also have serious side effects. The present study was thus designed to explore in vitro the antitumor effects of ambrosin sesquiterpene lactone against human drug-resistant breast cancer cells (MDA-MB-231).

Expression of glucose-regulated protein 78 as prognostic biomarkers for triple-negative breast cancer.

Introduction: Glucose-regulated protein78(GRP78) is a stress - induced endoplasmic reticulum chaperone protein. it is closely related to the occurrence, development, proliferation, differentiation and drug resistance of breast cancer. However, the association and clinicopathological features between GRP78 and triple negative breast cancer (TNBC) remain to be studied.

Inhibition of cancer cell growth by Tangeretin flavone in drug-resistant MDA-MB-231 human breast carcinoma cells is facilitated via targeting cell apoptosis, cell cycle phase distribution, cell invasion and activation of numerous Caspases.

Purpose: In this study, the anticancer effects of a natural flavonoid-Tangeretin, were examined against the drug-resistant MDA-MB-231 breast cancer (BC) cell line and the normal breast cell line Hs 841.T.

Methods: The MTT assay was employed for cell viability determination.

Therapeutic activity of DCC-2036, a novel tyrosine kinase inhibitor, against triple-negative breast cancer patient-derived xenografts by targeting AXL/MET.

Triple-negative breast cancer (TNBC) is insensitive to endocrine therapies and targeted therapies to human epidermal growth factor receptor-2 (HER2), estrogen receptor (ER) and progesterone receptor (PR). New targets and new targeted therapeutic drugs for TNBC are desperately needed. Our study confirmed that DCC-2036 inhibited the proliferation, invasion, migration and epithelial-mesenchymal transition (EMT) of TNBC cells as well as induced apoptosis.

Role of TXNDC5 in tumorigenesis of colorectal cancer cells: In vivo and in vitro evidence.

Thioredoxin domain‑containing 5 (TXNDC5) is reportedly overexpressed in colorectal cancer (CRC) and is therefore considered an oncogene. However, the role of TXNDC5 in CRC tumorigenesis remains unclear. The present study aimed to explore the role of TXNDC5 in CRC tumorigenesis in vitro and in vivo under hypoxic and normoxic conditions.

Serum miR-20a is a promising biomarker for gastric cancer.

Gastric cancer (GC) is a common type of cancer, particularly in China. Numerous studies have demonstrated that circulating microRNAs (miRNAs) have potential applications as noninvasive biomarkers for cancer diagnosis and prognosis. Microarray-based serum miRNA profiling was performed on the serum of 12 paired pre- and post-operative GC patients to screen differentially expressed serum miRNAs.

Heterogeneous nuclear ribonucleoprotein K is overexpressed and associated with poor prognosis in gastric cancer.

Heterogeneous nuclear ribonucleoprotein K (hnRNP K) is one of the major pre-mRNA-binding proteins, that is involved in translational modifications. In our previous studies, we found that hnRNP K is associated with human gastric cancer. The protein levels of hnRNP K were detected in cell lines and tissue microarrays.

Hypoxia regulates stemness of breast cancer MDA-MB-231 cells.

Human breast cancers include cancer stem cell populations as well as non-tumorigenic cancer cells. Breast cancer stem cells possess self-renewal capability and thus are the root cause of recurrence and metastasis of malignant tumors. Hypoxia is a fundamental pathological feature of solid tumor tissues and exerts a wide range of effects on the biological behavior of cancer cells.

Neuron navigator 2 overexpression indicates poor prognosis of colorectal cancer and promotes invasion through the SSH1L/cofilin-1 pathway.

Background: Neuron navigator 2 (NAV2) encodes a member of the neuron navigator gene family, which plays a role in tumorigenesis and cell migration. However, the prognostic value of NAV2 expression in colorectal cancer (CRC) patients and the potential pathway through which NAV2 promotes migration and invasion in CRC cell lines is poorly understood.

Methods: The expression level of NAV2 was detected in CRC tissues from two different CRC cohorts by immunohistochemistry, qRT-PCR and Western blotting; the correlation between NAV2 expression and clinicopathological characters was analyzed, and the prognostic value of NAV2 expression was analyzed using a Cox regression model.

U6 is not a suitable endogenous control for the quantification of circulating microRNAs.

Recently, microRNAs have been detected in serum and plasma, and circulating microRNA (miRNA) profiles have now been associated with many diseases such as cancers and heart disease, as well as altered physiological states. Because of their stability and disease resistance, circulation miRNAs appear to be an ideal material for biomarkers of diseases and physiological states in blood. However, the lack of a suitable internal reference gene (internal reference miRNA) has hampered research and application of circulating miRNAs.
