Mouse models of chemotherapy related leukocytopenia were established by intraperitoneal injection of cyclophosphamide (CTX).

A Prognostic Analysis of Male Breast Cancer (MBC) Compared with Post-Menopausal Female Breast Cancer (FBC).

Background: Male breast cancer (MBC) is known to be rare compared with female breast cancer (FBC) and to account for only 1% of all breast cancers. To date, male patients diagnosed with breast cancer are normally treated based on the guidelines for FBC. Specifically, studies have found that diagnosing and treating MBC patients under the guidelines for the treatment of post-menopausal FBC are more favorable than are those of pre/peri-menopausal FBC from a physiological perspective because MBC and post-menopausal FBC patients show high estrogen receptor (ER) expression in the tumor and low estrogen expression in the body.

Overexpression of ILK1 in breast cancer associates with poor prognosis.

Integrin-linked kinase 1 (ILK1), a member of the serine/threonine kinases, has been demonstrated to be associated with numerous biological and pathological processes. However, the role of ILK1 in breast cancer has not been thoroughly elucidated. The purpose of this study was to assess ILK1 expression and to explore its contribution to breast cancer.

The prognostic significance of molecular subtype for male breast cancer: a 10-year retrospective study.

Background: Male breast cancer (MBC) is rare. Molecular subtype has been utilized widely in female breast cancer. But the relationship between subtype and prognosis in MBC patients is still unknown.

The apelin-APJ pathway exists in cardiomyogenic cells derived from mesenchymal stem cells in vitro and in vivo.

Our previous study demonstrated that apelin level increased significantly after the treatment of intracoronary implantation of bone marrow mononuclear cells (BMMCs), followed by the improvement of cardiac function in patients with severe ischemic heart failure. The present studies both in vivo and in vitro explored whether mesenchymal stem cells derived from bone marrow (BMSCs) activate the apelin-APJ pathway when differentiating into cardiomyogenic cells. Isolated BMSCs from rat femurs and tibias were cultured and expanded for three passages, labeled with DAPI, and treated with 5-azacytidine (5-AZ).

[Transfection of bone marrow mesenchymal stem cells by adeno-associated virus 2/1 vector].

This study was aimed to investigate the transfection efficacy of recombinant adeno-associated virus 2/1 (rAAV2/1) on bone marrow mesenchymal stem cells (BMMSCs) at different multiplicities of infection (MOI) and time, and effect of transfection on growth of rat BMMSCs. The rat BMMSCs cultured in vitro were transfected by using rAAV2/1 with enhanced green fluorescent protein (rAAV2/1-EGFP) at MOI of 1 x 10(4), 1 x 10(5) and 1 x 10(6); the EGFP expression was observed by fluorescent microscopy at 3, 7 and 14 days. The viability, proliferation multiple, differentiation ability of daughter cells were detected for evaluating the effect of rAAV2/1 on survival, proliferation and differentiation of BMMSCs and the fluorescence index (FI) were determined by flow cytometry.
