Endometriosis is defined as a condition with endometrium-like tissues migrating outside of the pelvic cavity. However, the mechanism of endometriosis is still unclear. Lactate can be covalently modified to lysine residues of histones and other proteins, which is called lactylation.

Herein, one-dimensional (1D) Fe-MoS microtubes were designed to prepare tubular Fe-doped MoS composites with MoO microrods as self-sacrificing precursors. Remarkably, the results indicated that the generated ammonia released from the sulfidation process led to the dissolution of MoO cores and the generation of a tubular structure.

It plays a significant role in supporting tumor growth and is expected to provide novel therapeutic ideas for treating tumors that are resistant to conventional therapies. We investigated the expression pattern of angiogenesis-related genes (ARGs) in ovarian cancer (OV) from public databases, in which the patients could be classified into two differential ARG clusters.

For ratiometrically imaging peroxynitrite (ONOO) in living cells, we devised and fabricated a novel fluorescent nanoprobe, NC-NP, in this study. To achieve ratiometric fluorescence response towards ONOO, NC-NP used 3-(2-benzothiazolyl) coumarin (Cou-Bz) as the internal reference and 1,8-naphthimide derivative (Naph-PN) as a fluorescent ONOO probe. These compounds were incorporated into an amphiphilic block polymer called Pluronic F-127.

In this study, new strongly coupled nickel-cobalt alloy/N,P,S co-doped carbon (NPSC) nanocages are rationally designed chemical etching of the ZIF-67 dodecahedron with Ni under sonication at room temperature, followed by poly(cyclotriphosphazene--4,4'-sulfonyldiphenol) (PZS) coating and subsequent carbonization treatment in a nitrogen atmosphere. When evaluated as a catalyst for 4-NP or an adsorbent for His-rich protein, the as-prepared NiCo@NPSC nanocages obtained at 700 °C show better performance than those obtained at other temperatures (500 and 900 °C).

However, a poor specificity of prostate specific antigen (PSA) testing alone fostering overdetection and overtreatment, remains a great controversy in prostate cancer (PCa) screening. Here we report an electrochemical aptasensor using hierarchical MoS nanostructuring and SiO nano-signal amplification for simultaneous detection of dual PCa biomarkers, PSA and sarcosine, to enhance the diagnostic performance of PCa.

Nanomaterials with enzyme-like activity (nanozymes) have been of great interest in broad applications ranging from biosensing to biomedical applications. Despite that much effort has been devoted to the development of the synthesis and applications of nanozymes, it is essential to understand the interactions between nanozymes and most commonly used biomolecules, i.e.

Patients And Methods: Here, we employed the next-generation sequencing (NGS) platform to identify mtDNA mutations of the unrelated high-grade serous ovarian cancer (HGSOC) patients.
To evade immune defense, cancer cells can employ extracellular vesicles (EVs) to inhibit the anti-tumor activity of lymphocytes in the tumor microenvironment. However, the mechanisms and key molecules that mediate the effects of EVs on lymphocytes are unclear. We used Quantibody Human Cytokine Antibody Array 440 to determine the tumor immunity-related cytokine profile of peripheral blood lymphocytes (PBLs) stimulated with EVs derived from peritoneal washes or malignant ascites.

Increasing evidence suggests that alterations of telomere length might be implicated in carcinogenesis. However, the association between cervical cancer and telomere length remains unknown.

The elevated expression of miR-146a is involved in the pathogenesis of cancers generally, but its role in cervical cancer has not been fully elucidated. In the present study, we assessed the expression of miR-146a in G>C polymorphisms and confirmed that the overexpression of miR-146a promoted cervical cancer cell viability.

Methods: Eligible case-control studies were identified dated until July 2017. Pooled odds ratios (ORs) were used to assess the strength of the association between the two variants and cervical cancer risk.

Objective: Tumor necrosis factor α (TNF-α), secreted mainly by activated macrophages, is recently involved in fighting against tumorigenesis. Tumor necrosis factor α -308 G>A, the common polymorphism in the promoter of TNF-α, has been implicated to alter the risk of cervical cancer, yet the results of relative studies are inconclusive or controversial. To derive a more precise estimation of the relationship, we performed a meta-analysis based on 8 studies.

A G>C polymorphism (rs2910164) is located on the passenger strand of the precursor of miR-146a, which could alter mature miR-146a expression. We hypothesized that a possible association exists between miR-146a gene polymorphisms and cervical cancer risk in a population-based control study of female residents in Jiangsu Province.
