乳腺癌生存期相关长非编码 MAPT-AS1 及其共表达基因筛选与验证

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2019
【目的】筛选乳腺癌患者生存期相关差异表达长链非编码RNA(lncRNA)及其共表达基因,并验证其乳腺癌细胞中的表达情况。【方法】通过TCGA数据库筛选943例RNA-seq数据信息:(837例乳腺癌患者+106例正常对照),发现长非编码MAPT-AS1高表达,乳腺癌患者生存期更长。构建长非编码MAPT-AS1过表达和干扰质粒,将构建好的质粒转染乳腺癌细胞株T47D,并用嘌呤霉素筛选出稳定表达的T47D细胞株,通过RT-qPCR验证长非编码MAPT-AS1及其共表达基因的表达情况。【结果 ...

Dual Synergistic Effects in a Ce‐Modified MnO2/MnO Heterostructure Enabling Outstanding Acidic Oxygen Evolution

open access: yesRare Metals, EarlyView.
ABSTRACT The development of highly efficient and stable nonprecious metal electrocatalysts for the acidic oxygen evolution reaction (OER) is crucial to advance proton exchange membrane (PEM) water electrolysis. In this work, a dual synergistic strategy was proposed by constructing a Ce‐modified MnO2/MnO heterostructure.

烧伤创面内表皮生长因子、表皮生长因子受体、C-myc三种基因表达变化的临床观察

open access: yesZhongguo shiyan zhenduanxue, 2010
目的为探讨烧伤创面愈合机理,了解烧伤创面内表皮生长因子基因、表皮生长因子受体基因和C-myc基因的变化,为临床治疗提供依据。方法我们对25例病人烧伤创面的不同部位应用原位杂交方法,观察表皮生长因子基因、表皮生长因子受体基因和C-myc基因在烧伤创面肉芽中心部(肉芽中心部)、肉芽与愈合皮肤的交界部(创面交界部)、愈合皮肤部位(创面愈合部)和自身正常皮肤对照部位内表达强度和分布的特点。结果同一部位烧伤创面内,表皮生长因子基因和C-myc基因在交界部表达最强;烧伤创面中心部位表达次之,烧伤创面愈合部位表达较弱;

Silencing of PKM2 promotes Fas-Dependent Apoptosis via P53 -Mediated in Gastric cancer Cells [PDF]

open access: yes, 2015
背景和目的:PKM2作为丙酮酸激酶(pyruvatekinaseisoenzyme,PK)家族成员,在肿瘤中呈现高表达,并且在肿瘤能量代谢过程中起到关键作用。近期研究发现,PKM2还具备转录因子活性,参与调控细胞增殖与迁移侵袭,在恶性肿瘤的发生发展中发挥重要作用。我们研究发现,胃癌细胞株BGC823及AGS中基因沉默PKM2后,促进了顺铂诱导的细胞凋亡,由此表明PKM2可以减低胃癌细胞对化疗药物的敏感性,但具体机制有待探索 ...

An Ultrasmall Strontium‐Loaded Polydopamine Nanoformulation for Near‐Infrared‐Enhanced Periodontitis Therapy via Photodynamic Gas‐Promoted Antibacterial and Bone Repair

open access: yesRare Metals, EarlyView.
ABSTRACT Periodontitis is a chronic infectious oral disease triggered by periodontopathogenic bacteria, resulting in the progressive inflammation and destruction of the tissues surrounding teeth. To achieve reprogramming of the infectious microenvironment for periodontitis therapy, a nanoformulation was proposed by loading polydopamine (PDA) with ...

The optimized expression technology of marine animal-sourced antimicrobial peptides in Pichia pastoris and the development of antimicrobial peptide as feedstuff additive [PDF]

open access: yes, 2015
抗生素污染问题是目前影响我国水产养殖业可持续健康发展的重大科技问题,抗生素(antibiotics)作为常用抗菌药物,被广泛应用于水产养殖业,但是抗生素超标所引起的细菌耐药性问题已成为全球公共健康问题,因此寻找抗生素的有效替代品是目前国内外本领域的研究热点之一。抗菌肽(antimicrobialpeptide)是先天性免疫的重要组分,广泛存在于生物界的各个门类,进化上相对保守,具有广谱抗菌活性、且不会产生细菌耐药性,被预言为最有希望替代抗生素的天然药物,具有广阔的应用前景 ...
