Two candidate genes (ZmbZIP113 and ZmTSAH1) controlling low-temperature germination ability were identified by QTL-seq and integrative transcriptomic analyses. The functional verification results showed that two candidate genes positively regulated the low-temperature germination ability of IB030. Low-temperature conditions cause slow maize (Zea mays L.

As the resident macrophages of the brain's innate immune system, microglial cells are key modulators in the neurodegenerative disease Alzheimer's disease (AD). In particular, the activation and accumulation of microglial cells around amyloid plaques is considered to result in chronic neuroinflammation. Although the pathologic mechanism remains to be fully elucidated, inflammation has been shown to be critical in the pathogenesis of AD.

Background: The aim of the present study was to investigate the potential effects of the 5,10,15,20-tetrakis (1-methylpyridinium-4-yl) porphyrin (TMPyP4) on the proliferation and apoptosis of human cervical cancer cells and the underlying mechanisms by which TMPyP4 exerted its actions.

Results: After human cervical cancer cells were treated with different doses of TMPyP4, cell viability was determined by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) method, the apoptosis was observed by flow cytometry (FCM), and the expression of p38 mitogen-activated protein kinase (MAPK), phosphated p38 MAPK (p-p38 MAPK), capase-3, MAPKAPK2 (MK-2) and poly ADP-ribose polymerase (PARP) was measured by Western blot analysis. The analysis revealed that TMPyP4 potently suppressed cell viability and induced the apoptosis of human cervical cancer cells in a dose-dependent manner.

Pain is the most pronounced complaint of women with endometriosis, however the underlying mechanism is still poorly understood. In the present study, the authors evaluate the effect of transient receptor potential vanilloid type 1 (TRPV1) of dorsal root ganglia (DRG) on endometriosis-associated pain. A total of 36 SD rats were randomly divided into a sham group (n=9) and a Model group (n=27), accepted auto‑transplanted pieces of fat or uterus to the pelvic cavity.

Angiogenesis is an important pathogenesis of Endometriosis. Vascular endothelial growth factor C (VEGF-C) is one of the most important factor in the regulation of both normal and abnormal angiogenesis. Anti-angiogenic treatment of endometriosis is still in the exploratory stage.

Endometriosis, diagnosed with ectopically implanted endometrial stromal cells (ESC) and epithelial cells to a location outside the uterine cavity, seriously threaten the quality of life and reproductive ability of women, yet the mechanisms and the pathophysiology of the disease remain unclear. Specially, the functional changes of ESC during endometriosis progression need in-depth investigation. In this study, we characterized mechanical properties of normal ESC (NESC) from healthy women and eutopic ESC (EuESC) and ectopic ESC (EcESC) from endometriosis patients.

Objective: To investigate the differentiation conditions of bone marrow mesenchymal stem cells (BMSCs) into endometrial epithelial cells and to confirm the effect of 17β-estradiol in this process.

Study Design: BMSCs were cultured alone or co-cultured with endometrial stromal cells (EStCs) in control/differentiation medium (17β-estradiol, growth factors) and were co-cultured with EStCs in different concentrations of 17β-estradiol. Flow cytometry and immunocytochemistry were used to identify the isolated cells.

POF (premature ovarian failure) is a distressing condition that is a common cause of infertility. No effective treatment is available to overcome the loss of fertility. A method to derive oestrogen from miPSCs (mouse-induced pluripotent stem cells) was explored as a potential treatment for POF.

Objective: To establish a satisfactory lung metastasis model of human choriocarcinoma using severe combined immunodeficient (SCID) mice and explore the appropriate cell concentration for the model.

Methods: Forty SCID mice aged between 5 - 6 weeks were randomly divided into four groups. 1 × 10(7) cells/ml × 0.

Objective: To investigate the expression of exogenous gene transferred by piggyBac (PB) transposon in various gynecological malignant cell lines and reveal its potential application of gene therapy in gynecological cancer.

Methods: Amplified herpes simplex virus thymidine kinase (HSV-tk) gene coding region by PCR and integrated it into PB expression vector, PB[Act-RFP]DS, for reconstructing PB[Act-RFP, HSV-tk]DS (pPB/TK). By using different transfection reagents: FuGENE HD, jetPEI, lipofectamine 2000, pPB/TK together with helper plasmid Act-PBase were cotransfected into four mostly common gynecological malignant tumor cell lines HeLa, JEG-3, SKOV3 and HEC-1B.

Human papillomavirus 58 (HPV58) is one type of HPV with high risk of causing cervical cancer. Unusually high prevalence of HPV58 has been reported in Asia, Africa and some other areas. However, due to the scattered distribution of global data, in addition to the lack of data of some HPV58 high-incidence nations and regions, like Mainland China, a comprehensive analysis of the global geographical distribution of HPV58 remains blank so far.

Chemotherapy is an important treatment for ovarian cancer. However, conventional chemotherapy has inevitable drawbacks due to side effects from nonspecific biodistribution of the chemotherapeutic drugs. To solve such problem, targeted delivery approaches were developed.
