A novel LRR receptor-like kinase BRAK reciprocally phosphorylates PSKR1 to enhance growth and defense in tomato.

Plants face constant threats from pathogens, leading to growth retardation and crop failure. Cell-surface leucine-rich repeat receptor-like kinases (LRR-RLKs) are crucial for plant growth and defense, but their specific functions, especially to necrotrophic fungal pathogens, are largely unknown. Here, we identified an LRR-RLK (Solyc06g069650) in tomato (Solanum lycopersicum) induced by the economically important necrotrophic pathogen Botrytis cinerea.

Plant -acylethanolamines play a crucial role in defense and its variation in response to elevated CO and temperature in tomato.

The ubiquitous lipid-derived molecules acylethanolamines (NAEs) have multiple immune functions in mammals, but their roles and mechanisms in plant defense response during changing environment remain largely unclear. Here, we found that exogenous NAE18:0 and NAE18:2 promoted defense against the necrotrophic pathogen but suppressed defense to the hemi-biotrophic pathogen pv. () DC3000 in tomato.

GSK3 inhibitor suppresses cell growth and metabolic process in FLT3-ITD leukemia cells.

Glycogen Synthase Kinase-3 (GSK-3) was recently implicated in the dysregulated biology of acute myeloid leukemia (AML). Low concentrations of GSK-3 inhibitors, SB216763 and BIO, suppressed the proliferation of AML cells with FLT3-ITD as early as 24 h after treatment. BIO was used in subsequent assays since it exhibited higher inhibitory effects than SB216763.

Correction: The novel leucine-rich repeat receptor-like kinase MRK1 regulates resistance to multiple stresses in tomato.

A novel leucine-rich repeat receptor-like kinase MRK1 regulates resistance to multiple stresses in tomato.

Leucine-rich repeat receptor-like kinases (LRR-RLKs) are ubiquitous in higher plants, which act as receptors of extracellular signals to trigger multiple physiological processes. However, the functions of the majority of LRR-RLKs remain largely unknown, especially in tomato (Solanum lycopersicum L.).

GALNT14 regulates ferroptosis and apoptosis of ovarian cancer through the EGFR/mTOR pathway.

Chemoresistance usually occurs in ovarian cancer. We aimed to explore the mechanisms of chemoresistance. Western blotting assay was used to detect the expression of GALNT14.

The regulatory module MdBT2-MdMYB88/MdMYB124-MdNRTs regulates nitrogen usage in apple.

Less than 40% of the nitrogen (N) fertilizer applied to soil is absorbed by crops. Thus, improving the N use efficiency of crops is critical for agricultural development. However, the underlying regulation of these processes remains largely unknown, particularly in woody plants.

Knockdown of NRSF inhibits cell proliferation of ovarian cancer via activating Hippo pathway.

Aims: Ovarian cancer is the most leading cause of deaths among gynecologic malignancies, and Neuron-restrictive silencer factor (NRSF) can be upregulated or downregulated according to the type of tumor. However, the expression and function of NRSF in ovarian cancer is still unknown.

Main Methods: Expression of NRSF in normal ovary and ovarian cancer cells were evaluated by quantitative PCR (qPCR).

[Pregnancy outcome in a woman with premature ovarian insufficiency complicated by systemic lupus erythematosus during pregnancy: a case report].

We report a case of in vitro fertilization and embryo transfer (IVF?ET) with oocyte donation in a woman with premature ovarian insufficiency (POI) complicated by systemic lupus erythematosus (SLE) during pregnancy. The patient had a diagnosis of POI 4 years earlier and 11 weeks after successful pregnancy by IVF?ET with oocyte donation in 2003, she presented with facial edema, and further examinations confirmed the diagnosis of lupus nephritis. She received treatment with prednisone to control the activity of SLE and aspirin and low?molecular?weight heparin to improve placental blood flow with close monitoring of gravida and fetus throughout pregnancy.

Long Noncoding RNAs: Potential Regulators Involved in the Pathogenesis of Polycystic Ovary Syndrome.

Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility in women of reproductive age, and its etiology remains poorly understood. Altered activities of long noncoding RNAs (lncRNAs) have been associated with human diseases and development. However, the roles of lncRNAs are unknown in reproductive medicine.

Impact of Abnormal DNA Methylation of Imprinted Loci on Human Spontaneous Abortion.

Currently, there is a growing concern regarding the safety of assisted reproductive technology (ART) due to increased risk of spontaneous abortion (SA) and imprinting disorders in ART-conceived offspring. Early investigations suggested that aberrant genetic imprinting may be related to pregnancy loss; however, few studies have used human tissue specimens. Here the DNA methylation patterns of 3 imprinted genes, including maternally inherited GRB10 and the paternally inherited IGF2 and PEG3 genes, were evaluated in human chorionic villus samples by pyrosequencing and bisulfite sequencing polymerase chain reaction.

[Clinical outcome of in vitro fertilization or intracytoplasmic sperm injection-embryo transfer in women aged 40 years and above].

Objective: To investigate the clinical outcomes in vitro fertilization or intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) in women aged over 40 years.

Methods: We retrospectively analyzed 1050 non-donor IVF/ICSI-ET cycles performed from January, 2007 to December, 2015 in women at the age 40 years or above, including 393 women at 40 years of age, 266 at 41 years, 158 at 42 years, 107 at 43 years, 64 at 44 years, and 65 at 45-51 years. The clinical characteristics and outcomes of the women in different age groups were compared and analyzed.

[Outcome analysis of monozygotic twin pregnancy conceived by assisted reproductive techniques].

Objective: To analyze the incidence, management, and outcomes of monozygotic twin (MZT) pregnancy conceived by assisted reproductive techniques (ART).

Methods: A retrospective analysis was performed of clinical pregnancies after in vitro fertilization and embryo transfer (IVF-ET) and introcytoplasmic sperm injection and embryo transfer (ICSI-ET) from January, 2010 to June 2015 at our center. We investigated the incidence, managements and outcomes of 94 MZT pregnancies.

DNA methyltransferase 3A promoter polymorphism is associated with the risk of human spontaneous abortion after assisted reproduction techniques and natural conception.

Purpose: The aim of this study was to explore the association of the DNA-methyltransferase (DNMT)-3A and DNMT3B promoter polymorphisms with the risk of human spontaneous abortion after assisted reproduction techniques (ARTs) and natural conception.

Methods: We collected tissues from women who underwent abortion procedures: (a) chorionic villus samples (CVS) and muscle samples (MS) from spontaneous abortions conceived by ART and natural cycle (study group), n = 152; and (b) CVS and MS from normal early pregnancy and second trimester (control group), n = 155. The single-nucleotide polymorphism (SNP) -448A > G in the DNMT3A promoter region and -149C/T polymorphism of DNMT3B were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and confirmed by sequencing.

Does lower dose of long-acting triptorelin maintain pituitary suppression and produce good live birth rate in long down-regulation protocol for in-vitro fertilization?

The effects of pituitary suppression with one-third depot of long-acting gonadotropin-releasing hormone (GnRH) agonist in GnRH agonist long protocol for in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) were investigated. A retrospective cohort study was performed on 3186 cycles undergoing IVF/ICSI with GnRH agonist long protocol in a university-affiliated infertility center. The pituitary was suppressed with depot triptorelin of 1.

Detection of HPV types and neutralizing antibodies in Gansu province, China.

A total of 82 samples from patients with cervical cancer (Group 1) and 50 samples from patients with other genital diseases (Group 2) were collected in Gansu, China. All 132 samples were tested for HPV DNA with a typing kit that can detect 21 types of HPV, and also tested for neutralizing antibodies against HPV-16, -18, -58, -45, -6, and -11 using pseudovirus-based neutralization assays. The results revealed that 28% (23/82) of sera in Group 1 were positive for type-specific neutralizing antibodies with a titer range of 160-640, of which 23.
