DNA methylation and gene expression profiling reveal potential association of retinol metabolism related genes with hepatocellular carcinoma development.

Background: Aberrant DNA methylation patterns play a critical role in the development of hepatocellular carcinoma (HCC). However, the molecular mechanisms associated with these aberrantly methylated genes remain unclear. This study aimed to comprehensively investigate the methylation-driven gene expression alterations in HCC using a multi-omics dataset.

Mebendazole exhibits potent anti-leukemia activity on acute myeloid leukemia.

Acute myeloid leukemia (AML) is one of the most common types of acute leukemia in adults with the lowest survival rate of all leukemia. Resistance to cytarabine and anthracycline-based chemotherapy is a major cause of treatment failure. Thus, finding new drugs with anti-leukemia activities and minimal side effect is urgently needed.

Targeting Androgen Receptor in Treating HER2 Positive Breast Cancer.

Androgen receptor (AR) is widely expressed in different subtypes of breast cancer (BC). However, it is unclear how AR functions in HER2 positive (+) BC. Knockdown of AR with shRNAs and a new generation anti-androgen drug, Enzalutamide, were used to explore the involvement of AR on the growth of HER2 + BC cells (HCC1954 and SKBR3).

Direct and indirect gene diagnosis of hemophilia A pedigrees in the Chinese population.

Hemophilia A (HA) is an X‑linked recessive hereditary disorder caused by defects in the coagulation factor VIII (FVIII) gene. In order to diagnose patients with presymptomatic HA and carriers, the present study conducted direct gene diagnosis for the common abnormalities in FVIII and subsequently performed indirect gene diagnosis for the other abnormalities in FVIII for Chinese HA pedigrees. Direct gene diagnosis was performed in 10 HA pedigrees using inverse shifting‑polymerase chain reaction to detect intron 22 inversion (inv22), intron 22 deletion, intron 22 duplication and inv1 of FVIII.

Shp1 positively regulates EGFR signaling by controlling EGFR protein expression in mammary epithelial cells.

SH2-domain containing protein tyrosine phosphatase 1 (Shp1/PTPN6) is mainly expressed in hematopoietic cells and acts a negative signaling regulator. Although Shp1 is also expressed in epithelial cells, the function of shp1 in normal epithelial is still less well understood, especially in regulating the growth of epithelial cells. In this study, different shRNAs and siRNAs against Shp1 were used to knockdown Shp1 expression in MCF10A, an immortalized mammary epithelial cell line.

Curcumin suppresses gastric tumor cell growth via ROS-mediated DNA polymerase γ depletion disrupting cellular bioenergetics.

Background: Curcumin, as a pro-apoptotic agent, is extensively studied to inhibit tumor cell growth of various tumor types. Previous work has demonstrated that curcumin inhibits cancer cell growth by targeting multiple signaling transduction and cellular processes. However, the role of curcumin in regulating cellular bioenergetic processes remains largely unknown.

[Protective effects of Curcumin analogue L6H4 on kidney from type 2 diabetic rats].

Objective: To investigate the protective effect of curcumin analogue L6H4 on the kidney from the type 2 diabetic rats.

Methods: Twenty-four SPF male SD rats were randomly divided into 3 groups(=8):normal control group(NC),diabetes mellitus group(DM) and DM+L6H4-treatment group(DT). After rats were fed with high-fat diet for 4 weeks, both the DM and DT groups were injected with streptozotocin intraperitoneally to induce type 2 diabetes mellitus models.
