Jiashu Chu, Zhong Chen
Histone is the core component of nucleosome and modification of amino acid residues on histone tails is one of the most pivotal epigenetic regulatory mechanisms. Histone acetylation or deacetylation is carried out by two groups of proteins: histone acetyltransferases (HATs) or histone deacetylases (HDACs), and has been proven to be tightly linked to regulation of gene expression in animals and vascular plants. The biological functions of HATs and HDACs in non-flowering plants remain largely unknown. We found that there are seven MpHAT genes and twelve MpHDAC genes present in the Marchantia genome, and the comprehensive protein sequence analysis of the HAT and HDAC families was introduced to investigate their potential functions...

Discerning the relationship between molecules involved in diseases based on their underlying biological mechanisms is one of the greatest challenges in therapeutic development today. Gestational diabetes mellitus (GDM) is one of the most common complications during pregnancy, which adversely affects both mothers and offspring during and after pregnancy. We have constructed two datasets of (GDM associated genes from affected mother and placenta to systematically analyze and evaluate their interactions like gene-gene, gene-protein, gene-microRNA (miRNA), gene-transcription factors, and gene-associated diseases to enhance our current knowledge, which may lead to further advancements in disease diagnosis, prognosis, and treatment...

The prevention and treatment of venous thromboembolism (VTE) poses distinct gender-specific challenges. Women of childbearing age are at an increased risk of VTE secondary to the transient risk factors of combined hormonal contraception (CHC) and pregnancy. Cancers specific to women are associated with a significant burden of VTE; whilst the incidence of VTE in localised breast cancer is 5 per 1000 person-years, more cases are seen due to the prevalence of breast cancer. Treatment of VTE in women can be complicated by abnormal uterine bleeding, now increasingly reported with direct oral anticoagulants (DOACs) as well as vitamin K antagonists...

Nausea and vomiting of pregnancy affect the majority of pregnancies, while the most severe version, hyperemesis gravidarum (HG), affects a much smaller subset of women. Despite the prevalence of nausea and vomiting of pregnancy and the severe consequences of HG, the pathophysiology of these conditions is not fully understood. Currently, it is thought that a combination of hormonal factors accounts for their development. Multiple treatments have been described for nausea and vomiting of pregnancy and HG with varying levels of success...

Endometrioid endometrial carcinoma, commonly known as type 1 endometrial cancer, accounts for >80% of endometrial carcinomas and is dependent on estrogen. We recently reported on the prognostic significance of the BIRC5 survivin gene in endometrial cancer. Estradiol induces survivin expression in estrogen receptor-positive, but not in estrogen receptor-negative, cancer cells. Kaempferol, a bioflavonoid, reportedly inhibits estrogen receptor-α (ERα) in hormone receptor-positive breast cancer cells. However, whether kaempferol-mediated inhibition of ERα suppresses survivin and induces cell death in endometrial cancer remains unclarified...

Adrenocortical carcinoma (ACC) is a rare solid tumor with an incidence of 0.5 to 2 cases per million per year. It affects women more commonly than men with a ratio of 1.5:1. Ectopic ACC are considered to be extremely rare with no exact incidence data yet. We report an interesting case of hepatic ACC in a young woman with clinical signs of virilization.A-21-year old Sundanese woman visited our endocrine clinic with progressive hirsutism over the face, body, and extremities starting 14 years previously. She had irregular, heavy periods when she was 7 years old...

INTRODUCTION: Breast cancer in younger patients is reported to be more aggressive and associated with lower survival; however, factors associated with age-specific mortality differences have not been adequately assessed. METHODS: We used data from the population-based California Cancer Registry for 38,509 younger (18-49 years) and 121,573 older (50 years and older) women diagnosed with Stage I-III breast cancer, 2005-2014. Multivariable Cox regression models were used to estimate breast cancer specific mortality rate ratios (MRR) and 95% confidence intervals (CI), stratified by tumor subtype, guideline treatment, and care at a National Cancer Institute-designated cancer center (NCICC)...

Rheumatoid Arthritis (RA) is a chronic autoimmune disease that results in the systemic inflammation principally affecting the capsule covering the articulating ends of the synovial joints. Pharmacological treatment involving analgesics and anti-inflammatory drugs including steroids suppress the symptoms and have no effect on disease progression. However, disease modifying anti rheumatic drugs (DMARD) used for the treatment were still analysed for their long term effects. Bromelain has been widely used as phytotherapeutic drug owing to its anti-inflammatory, analgesic, anti-tumor and fibrinolytic properties...

Stress exposure during development can impact both the expression of individual traits and associations between traits, but whether stress results in stronger or weaker associations between traits is unclear. In this study, we examined within- and among-trait associations for morphological and physiological traits in zebra finches (Taeniopygia guttata) exposed to corticosterone (CORT) during the nestling and fledging stages as well as in control birds. Birds exposed to CORT exhibited stronger within-trait correlations over time and stronger associations among traits...

Background The short stature homeobox-containing (SHOX) gene strongly affects height. Therefore, a better understanding of SHOX haploinsufficiency could be advantageous to early diagnosis and treatment. We investigated the rate of SHOX haploinsufficiency in patients of short stature and documented their anthropometric measurements. Methods Between 2010 and 2017, we evaluated 86 patients (70 females, 16 males; age 4.3-18 years) with clinical diagnoses of short stature and Madelung deformity (MD). Clinical abnormalities are presented for patients with MD with and without SHOX haploinsufficiency as determined by fluorescence in situ hybridisation (FISH)...

Endometriosis is common among those with infertility, although many cases go undiagnosed. This study was performed to determine whether empiric treatment with two months of depo-leuprolide 3.75 mg monthly (dep-GnRH-ag) and letrozole 5 mg daily improves pregnancy outcomes in patients with at least two unexplained failed embryo transfers (ETs) but without a previous diagnosis of endometriosis. A retrospective cohort study was performed with subjects who failed at least two good quality ET. The study excluded women with a known history of endometriosis or ovarian cysts (possible endometriomas)...
