Being able to perform adept goal-directed actions requires predictive, feed-forward control, including a mapping between the visually estimated target locations and the motor commands reaching for them. When the mapping is perturbed, e.g., due to muscle fatigue or optical distortions, we are quickly able to recalibrate the sensorimotor system to update this mapping. Here, we investigated whether early visual and visuomotor experience is essential for developing sensorimotor recalibration.

Feline morbillivirus (FeMV) is a recently discovered pathogen of domestic cats and has been classified as a morbillivirus in the Paramyxovirus family. We determined the complete sequence of FeMVUS5 directly from an FeMV-positive urine sample without virus isolation or cell passage. Sequence analysis of the viral genome revealed potential divergence from characteristics of archetypal morbilliviruses. First, the virus lacks the canonical polybasic furin cleavage signal in the fusion (F) glycoprotein.

Background Diabetes clinical trials have shown SGLT inhibition improves cardiovascular outcomes, yet the mechanism is not fully understood. Hyperglycemia is a common finding in diabetic and non-diabetic patients presenting with ACS and is a powerful predictor of prognosis and mortality. The role of hyperglycemia in ischemia-reperfusion injury (IRI) is not fully understood, and whether the Sodium Glucose Co-Transporter 1 (SGLT1) plays a role in infarct augmentation, before and/or after reperfusion, remains to be elucidated.

Background In the large intestine, the multipotent stem cells are located at the base of the crypt and differentiate into three main cell types: enterocytes, goblet cells, and enteroendocrine cells. Goblet cells’ main function is the synthesis and secretion of mucins. Genetic and epigenetic changes that provide survival advantages for stem or progenitor cells resulting in the deregulation of cellular differentiation are major causes of all carcinomas.

Background Prostate cancer (PCa) is one of the main causes of death in men all over the world. To date, the emerging issue is the search for new diagnostic and prognostic biomarkers to distinguish patients with different risk types. Recent studies of PCa biomarkers have drawn attention to the remarkable heterogeneity of this tumor. Tumor heterogeneity (TH) is the main limitation of the ability to use biomarkers’ gene panels in clinics because of different cell subclones within one tumor.

Background PIM 1 and PI3K/mTOR pathways are frequently dysregulated in prostate cancer and may lead to decreased survival invasion and metastasis. Moreover, anti-tumour drug resistance has been associated with the interconnection of these pathways. Furthermore, current treatments exhibit issues with toxicity.

Menopause is associated with the loss of LH ovulatory surges and enhanced visceral adiposity. Visceral fat depots increase from 5-8% at premenopause to 15-20% of total body fat at postmenopause. Here, we report that high-dose LH, hCG, or small molecule LH/CGR agonist ORG43553 injected twice-a-week into 14-weeks-old C57BL/6 male mice protects them from diet-induced obesity. Testosterone levels were elevated in mice treated with LH or hCG, but not with ORG43553.

目的 通过表达谱芯片筛选卵巢癌(OC)有价值的核心长链非编码RNAs(lncRNAs)分子,并进行表达验证和分析。方法 收集宁夏医科大学总医院2018年1月至2019年6月OC组织36份,正常卵巢组织22份,以表达谱芯片检测差异表达lncRNAs和mRNAs分子,以real-time PCR验证lncRNAs表达,原位杂交验证关键核心lncRNA的表达,生物信息学分析lncRNA可能的功能。结果 相比于正常组织,癌组织中共有4 982个差异表达的lncRNA,以锌指E盒结合同源盒蛋白2-AS1(ZEB2-AS1)的高表达最为显著(P＜0.05);ZEB2-AS1在肝癌、结肠癌和肾癌等多个癌组织中过表达;表达水平与肿瘤大小、病理分级、病理分型及临床分期均有相关性(P＜0.05),且高表达导致总生存期和无病生存期降低(P＜0.05)。ZEB2-AS1具有多个microRNA结合位点,与相应邻近基因ZEB2的表达情况一致。结论 ZEB2-AS1在卵巢癌中异常表达,提示ZEB2-AS1具有重要的研究价值。

There are few prostate cancer prognostic biomarkers. However, clinical difficulties in distinguishing between aggressive and non-aggressive tumors have been observed. CD73 is a 70-kDa glycosylphosphatidylinositol (GPI)-linked ecto-enzyme that reduces antitumor immunity in mouse models of tumor, particularly prostate cancer. It's believed to be a promising biomarker for predicting the clinical development and prognosis of certain tumor types. Its function in prostate cancer, however, is unknown.

Since epigenetic modifications differ from cell to cell, detecting the DNA methylation status of individual cells is requisite. Therefore, it is important to conduct "morphology-based epigenetics research", in which the sequence-specific DNA methylation status is observed while maintaining tissue architecture. Here we demonstrate a novel histochemical technique that efficiently shows the presence of a single methylated cytosine in a sequence-dependent manner by applying ICON (interstrand complexation with osmium for nucleic acids) probes.
