Single-Cell Transcriptome Analysis of Small Cell Neuroendocrine Carcinoma of the Endometrium Reveals as a Potential Biomarker for Diagnosis and Treatment.

Background: As a dedifferentiated tumor, small cell endometrial neuroendocrine tumors (NETs) are rare and frequently diagnosed at an advanced stage with a poor prognosis. Current treatment recommendations are often extrapolated from histologically similar tumors in other sites or based on retrospective studies. The exploration for diagnostic and therapeutic markers in small cell NETs is of great significance.

LATS1/2 loss promote tumor immune evasion in endometrial cancer through downregulating MHC-I expression.

Background: LATS1/2 are frequently mutated and down-regulated in endometrial cancer (EC), but the contributions of LATS1/2 in EC progression remains unclear. Impaired antigen presentation due to mutations or downregulation of the major histocompatibility complex class I (MHC-I) has been implicated in tumor immune evasion. Herein, we elucidate the oncogenic role that dysregulation of LATS1/2 in EC leads to immune evasion through the down-regulation of MHC-I.

Association between depression or anxiety symptoms and immune-inflammatory characteristics in in-patients with tuberculosis: A cross-sectional study.

Background: Depression and anxiety are major psychological issues among patients with tuberculosis (TB) owing to chronic and complex treatments, have been reported to be closely correlated with immune and inflammation. However, the association of peripheral immune-inflammatory characteristics with depression/anxiety symptoms in in-patients with TB has rarely been reported.

Methods: A cross-sectional study of 338 in-patients with TB from 3 hospitals in China were enrolled to investigate their depression and anxiety status by using the nine-item Patient Health Questionnaire (PHQ-9) and seven-item Generalized Anxiety Disorder Scale (GAD-7).

Association of Three SNPs Loci of Kelch-Like-ECH-Associated Protein 1 (Human) with Tuberculosis in Chinese Han Population.

Purpose: Progression from latent tuberculosis infection (LTBI) to pulmonary TB (PTB) was associated with genetic polymorphisms, but there were limited genetic polymorphism data on LTBI and PTB. We aimed at examining the association of KEAP1 gene polymorphisms with PTB and LTBI.

Patients And Methods: PTB patients and close contacts of PTB patients were recruited from West China Hospital of Sichuan University.

Compartmentalized localization of 11β-HSD 1 and 2 at the feto-maternal interface in the first trimester of human pregnancy.

Glucocorticoids are engaged in a number of actions at the feto-maternal interface for the establishment of early pregnancy. However, excessive glucocorticoids can be deleterious to fetal development. Therefore, compartmentalized distribution of 11β-hydroxysteroid dehydrogenase 1 and 2 (11β-HSD1 and 2), which regenerates and inactivates cortisol respectively, would ensure an optimal cortisol concentration at the feto-maternal interface for the establishment of early gestation.

Effect of PFOS on glucocorticoid-induced changes in human decidual stromal cells in the first trimester of pregnancy.

Perfluorooctane sulfonate (PFOS) is a surfactant and used in treating products for waterproofing and non-stick applications. PFOS has potential influence on reproductive function but the effect of PFOS exposure on the decidual functions remains unknown. By using primary human decidual stromal cells of early pregnancy we demonstrated that PFOS inhibited decidualization of the stromal cells as well as decidualization-induced upregulation of 11β-HSD1, an enzyme that regenerates biologically active cortisol from its inactive counterpart cortisone.

The acetyl-CoA carboxylase enzyme: a target for cancer therapy?

As a rate-limiting enzyme, the acetyl-CoA carboxylase (ACC) is essential for fatty acid synthesis. Traditionally, the ACC has been a target of metabolic syndrome and obesity. Recent research has demonstrated that malignant tumors have a high energy flow, thus having a great ability to synthesize fatty acids.

Inhibition of 11β-HSD2 expression by triclosan via induction of apoptosis in human placental syncytiotrophoblasts.

Context: Triclosan is widely used in personal care products for its broad spectrum of antimicrobial effects, but triclosan is a potential endocrine disruptor. 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2) is a cortisol-inactivating enzyme that is highly expressed in human placental syncytiotrophoblasts to ensure normal fetal development in the presence of high levels of maternal cortisol in pregnancy.

Objective: We investigated the effects of triclosan on 11β-HSD2 and apoptosis and the relationship between these two events in human placental syncytiotrophoblasts.
