3-Deoxysappanchalcone isolated from shows anticancer effects on HeLa and PC3 cell lines: invasion, migration, cell cycle arrest, and signaling pathway.

To study the antitumor activity of compound 3-desoxysulforaphane (3-DSC) isolated from , SRB assay, clone formation assay, flow cytometric cell cycle assay, scratch assay, transwell assay, and molecular docking were used to investigate the inhibitory effect of 3-DSC on HeLa and PC3 cells. The results showed that 3-DSC inhibited the cell migration and invasion by down-regulating expression of N-cadherin, Vimentin, MMP-2, and MMP-9 in HeLa and PC3 cells; It also inhibits cell proliferation by promoting the expression of CDK1 (cyclin-dependent kinases 1) and CDK2 (cyclin-dependent kinases 2), which arrests the tumor cell cycle at G2 phase. 3-DSC inhibits phosphorylation of AKT and ERK and upregulates the expression of the tumor suppressor gene p53.

ABCG1 is Expressed in an LXR-Independent Manner in Patients with Type 2 Diabetes Mellitus.

Background: Patients with type 2 diabetes mellitus have a high cardiovascular risk due, in part, to abnormalities of high-density lipoprotein mediated cholesterol efflux. The ATP-binding cassette A1 and G1 play a pivotal role in the regulation of cholesterol efflux. However, the regulation of these transporters in type 2 diabetes mellitus remains obscure.

A novel missense mutation of RPGR identified from retinitis pigmentosa affects splicing of the ORF15 region and causes loss of transcript heterogeneity.

Mutations in the retinitis pigmentosa GTPase regulator (RPGR) gene, are the major cause of X-linked retinitis pigmentosa (RP), in which exon open reading frame 15 (ORF15) of RPGR has been implicated to play a substantial role. We identified a novel hemizygous missense mutation E585K of RPGR from whole-exome sequencing of RP. RNA-Seq analysis and functional study were conducted to investigate the underlying pathogenic mechanism of the mutation.

The Anti-tumor Activity and Mechanisms of rLj-RGD3 on Human Laryngeal Squamous Carcinoma Hep2 Cells.

Background: Laryngeal Squamous Cell Carcinoma (LSCC) is a malignant epithelial tumor with poor prognosis and its incidence rate increased recently. rLj-RGD3, a recombinant protein cloned from the buccal gland of Lampetra japonica, contains three RGD motifs that could bind to integrins on the tumor cells.

A Novel Mutant of rLj-RGD3 (rLj-112) Suppressed the Proliferation and Metastasis of B16 Cells through the EGFR Signaling Pathway.

Lj-RGD3, which contains three Arg⁻Gly⁻Asp (RGD) motifs, was first identified from the buccal glands of and has been shown to suppress the tumor progression in the previous studies. Apart from the three RGD motifs, Lj-RGD3 is also characterized by its high content of histidine in its amino acid sequence. In order to clarify whether the histidine-rich characterization of Lj-RGD3 is also associated with its anti-tumor activity, mutants were designed in which the three RGD motifs (Lj-112), or all histidines (Lj-27) or both (Lj-26) were deleted.

Steroid receptor coactivator-3 promotes bladder cancer through upregulation of CXCR4.

The three homologous members of the p160 SRC family (SRC-1, SRC-2 and SRC-3) mediate the transcriptional functions of nuclear receptors and other transcription factors, and are the most studied of all the transcriptional co-activators.
