Rab27b promotes endometriosis by enhancing invasiveness of ESCs and promoting angiogenesis.

Problem: Endometriosis (EMS) is an estrogen-dependent disease which is characterized with estrogen-dependent growth of ectopic endometrium and increased local estrogen production. EMS performs tumor-like biological functions such as invasiveness and angiogenesis. Rab27b is a member of the Rab family of GTPases, which is strongly associated with the growth, invasion and metastasis of a variety of tumors.

Towards a Better Understanding of Endometriosis-Related Infertility: A Review on How Endometriosis Affects Endometrial Receptivity.

Endometriosis is the most common cause of infertility. Endometrial receptivity has been suggested to contribute to infertility and poor reproductive outcomes in affected women. Even though experimental and clinical data suggest that the endometrium differs in women with endometriosis, the pathogenesis of impaired endometrial receptivity remains incomplete.

Anti-diabetic effect of extract on 57BL/KsJ db-/db- mice.

Diabetes mellitus is characterized by high blood glucose levels. Increased levels of reactive oxygen species (ROS) may disrupt insulin signaling and result in insulin resistance. The extract (AOE) possesses powerful antioxidant activity and may therefore inhibit the development of insulin resistance.

Fibroblast Growth Factor 7 Regulates Proliferation and Decidualization of Human Endometrial Stromal Cells via ERK and JNK Pathway in an Autocrine Manner.

Decidualization is an essential activity of the endometrium in pregnancy, but the molecular mechanisms involving the initiation and maintenance have not yet been clarified. In the present study, we examined the expression of fibroblast growth factor 7 (FGF7) in endometria, normal decidua, and abortion decidua from miscarriage by immunohistochemistry. We analyzed the expression of FGF7 and FGFR2 and the levels of phosphorylated extracellular signal-regulated kinases (ERKs), c-Jun N-terminal kinase (JNK) in endometrial stromal cells (ESCs), and decidual stromal cells (DSCs) from early pregnancy or miscarriage by In-Cell Western assay.

Alpinia oxyphylla Miq. extract changes miRNA expression profiles in db-/db- mouse kidney.

Background: A number of dysregulated miRNAs have been identified and are proposed to have significant roles in the pathogenesis of type 2 diabetes mellitus or renal pathology. Alpinia oxyphylla has shown significant anti-inflammatory properties and play an anti-diabetes role. The objective of this study was to detect the alteration of miRNAs underlying the anti-diabetes effects of A.

TLR4 Activation Promotes the Secretion of IL-8 Which Enhances the Invasion and Proliferation of Endometrial Stromal Cells in an Autocrine Manner via the FAK Signal Pathway.

Problem: Chronic inflammation is important for the occurrence of endometriosis, but the molecular mechanisms are still poorly understood. TLR4 is not only expressed on immune cells but is also present in the human endometrium, and its regulation might be crucial for the pathogenesis of endometriosis.

Method Of Study: In this study, the expression of TLR4 in normal, eutopic endometrium, and ectopic tissues was analyzed by immunohistochemistry.

Krüppel-like Factor 4 Blocks Hepatocellular Carcinoma Dedifferentiation and Progression through Activation of Hepatocyte Nuclear Factor-6.

Purpose: Tumor differentiation is a behavioral index for hepatocellular carcinoma (HCC) and a prognostic factor for patients with HCC who undergo orthotopic liver transplantation (OLT). However, the molecular basis for HCC differentiation and prognostic value of the underlying molecules that regulate HCC differentiation are unclear. In this study, we defined a potential driver pathway for HCC differentiation and prognostication.

Decidual stromal cells recruit Th17 cells into decidua to promote proliferation and invasion of human trophoblast cells by secreting IL-17.

T helper 17 (Th17) cells have both regulatory and protective roles in physiological conditions. The Th17 subset and the cytokine interleukin-17A (IL-17A) have been implicated in the pathogenesis of certain autoimmune diseases, several types of cancer and allograft rejection. However, the role of Th17 cells at the maternal/fetal interface remains unknown.

Epidemiologic survey on hospitalized neonates in China.

Objective: To carry out a nationwide epidemiologic survey on the neonates in urban hospitals with an attempt to understand the disease spectrum and treatment outcomes of hospitalized neonates in China.

Methods: The clinical data of 43,289 hospitalized neonates from 86 hospitals in 47 Chinese cities (22 provinces) between January 1, 2005 and December 31, 2005 were retrospectively analyzed.

Results: The male:female ratio was 1.

[Myocardial protective effects of luteolin on isolated rat heart in hypothermic preservation].

Objective: To investigate the protective effect of luteolin on isolated rat heart in hypothermic preservation.

Methods: Forty male SD rats were randomly divided into 4 groups (n = 10): control group, luteolin low-dose group (7.5 micromol/L), middle-dose group (15 micromol/L) and high dose group (30 micromol/L).
