Hexafluoropropylene oxide trimer acid (HFPO-TA) exerts cytotoxic effects on leydig cells via the ER stress/JNK/β-trcp/mcl-1 axis.

Hexafluoropropylene oxide trimer acid (HFPO-TA) is an alternative to perfluorooctanoic acid (PFOA) and is widely used in various industries. The effects of HFPO-TA on the male reproductive system and the underlying mechanisms are still not fully understood. In this study, TM3 mouse Leydig cells were used as the main model to evaluate the cytotoxicity of HFPO-TA in vitro.

[Simiaotongzhuo Decoction for the treatment of type III prostatitis: A clinical observation].

Objective: To observe the clinical effect of Simiaotongzhuo Decoction (SMTZD) on the symptoms of type III prostatitis with damp-heat stagnation syndrome.

Methods: Using the randomized control method, we divided 140 cases of type III prostatitis with damp-heat stagnation syndrome into two groups and treated them orally with SMTZD at 200 ml per time bid (n = 65) and Tamsulosin Hydrochloride Sustained Release Capsules (THSRC) at 0.2 mg per time qd (n = 75), both for 6 weeks.

Enniatin B1 induces damage to Leydig cells via inhibition of the Nrf2/HO-1 and JAK/STAT3 signaling pathways.

Enniatin B1 (ENN B1) is a mycotoxin that can be found in various foods. However, whether ENN B1 is hazardous to the reproductive system is still elusive. Leydig cells are testosterone-generating cells that reside in the interstitial compartment between seminiferous tubules.

Exosomal miR-17-5p from human embryonic stem cells prevents pulmonary fibrosis by targeting thrombospondin-2.

Background: Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive, and irreversible lung disease characterized by pulmonary fibrosis and lung dysfunction, ultimately leading to respiratory failure. Many preclinical studies have investigated the therapeutic potential of stem cell-derived exosomes in this disease, particularly mesenchymal stem cell-derived exosomes. However, the effects of embryonic stem cell-derived exosomes in IPF remain unclear.

Scoparone induces both apoptosis and ferroptosis via multiple mechanisms in non-small-cell lung cancer cells.

The present study investigated the anti-tumour effects of scoparone, also known as 6,7-dimethoxycoumarin, in non-small-cell-lung cancer (NSCLC) cells. It was discovered that scoparone inhibited the proliferation and induced cell death of NSCLC cells. Scoparone induced both apoptosis and ferroptosis in NSCLC cells.

DNA methylation profile in the whole blood of acute coronary syndrome patients with aspirin resistance.

Background: Aspirin resistance (AR) results in major adverse cardiovascular events, and DNA methylation might participate in the regulation of this pathological process.

Methods: In present study, a sum of 35 patients with AR and 35 non-AR (NAR) controls were enrolled. Samples from 5 AR and 5 NAR were evaluated in an 850 BeadChip DNA methylation assay, and another 30 AR versus 30 NAR were evaluated to validate the differentially methylated CpG loci (DML).

Mesenchymal stem cells alleviate aging and .

Background: Aging is a natural and multi-factorial phenomenon associated with multiple human pathologies. Mesenchymal stem cells (MSCs) hold great promise in clinical fields of medicine including tissue repair, cardiovascular disease, and brain ischemic injury. The purpose of this study was to explore the roles of MSCs in improving the condition of aging cells, repairing aging tissues and organs, and extending the life span of elderly mice.

Transfer RNA-derived small RNAs and their potential roles in the therapeutic heterogeneity of sacubitril/valsartan in heart failure patients after acute myocardial infarction.

Background: It has been reported that sacubitril/valsartan can improve cardiac function in acute myocardial infarction (AMI) patients complicated by heart failure (HF). However, a number of patients cannot be treated successfully; this phenomenon is called sacubitril/valsartan resistance (SVR), and the mechanisms remain unclear.

Methods: In our present research, the expression profiles of transfer RNA (tRNA)-derived small RNAs (tsRNAs) in SVR along with no sacubitril/valsartan resistance (NSVR) patients were determined by RNA sequencing.

The DNAm levels of CREB5 (cg11301281) were associated with clopidogrel resistance.

Purpose: Clopidogrel resistance (CR) is mostly caused by interindividual variability of the platelet inhibition of clopidogrel, which may induce cardiovascular events. The aim of this research was to evaluate whether DNAm levels of CREB5 (cg01534253) are involved in CR among acute coronary syndrome (ACS) patients treated with clopidogrel.

Methods: 72 patients(36 CR and 36 non-CR) who underwent ACS were included in this study.

Systemic proteomics and miRNA profile analysis of exosomes derived from human pluripotent stem cells.

Background: Increasing studies have reported the therapeutic effect of mesenchymal stem cell (MSC)-derived exosomes by which protein and miRNA are clearly characterized. However, the proteomics and miRNA profiles of exosomes derived from human embryonic stem cells (hESCs) and human-induced pluripotent stem cells (hiPSCs) remain unclear.

Methods: In this study, we isolated exosomes from hESCs, hiPSCs, and human umbilical cord mesenchymal stem cells (hUC-MSCs) via classic ultracentrifugation and a 0.

CUGBP1, a crucial factor for heart regeneration in mice.

The mammalian heart is capable of achieving perfect regeneration following cardiac injury through sustained cardiomyocyte proliferation during the early period after birth. However, this regenerative capacity is lost by postnatal day 7 and throughout adulthood. CUGBP1 is critical for normal cardiac development but its role in heart regeneration remains unclear.

Bone marrow derived-mesenchymal stem cell improves diabetes-associated fatty liver via mitochondria transformation in mice.

Background: Non-alcoholic fatty liver disease (NAFLD) has become a global epidemic disease. Its incidence is associated with type 2 diabetes mellitus (T2DM). Presently, there is no approved pharmacological agents specially developed for NAFLD.

The effect of Xuefu Zhuyu decoction on clopidogrel resistance and its association with the P2Y12 Gene polymorphisms and promoter DNA methylation.

Some patients experience lesser degrees of platelet inhibition, which is known as clopidogrel resistance (CR). The goal of our study was to investigate the effects of Xuefu Zhuyu decoction on CR in coronary artery disease patients and whether P2Y12 polymorphisms and its methylation were related to drug response or not. 49 patients diagnosed with CR were randomly divided into control and treatment groups.

A novel antitumor compound nobiliside D isolated from sea cucumber ( Selenka).

An anticancer compound, triterpene glycoside, was isolated from Selenka. Its chemical structure and configuration were determined by two-dimensional nuclear magnetic resonance spectroscopy and electrospray ionization mass spectrometry. The novel active compound was identified as nobiliside D, with the molecular formula CHOSNa and chemical name 3-O-[-β-D-pyranosyl (1-2)-4'-O-sulfon-ate-β-D-xylopyranosyl]-alkoxy-9-ene-3β, 12α, 17α, 25β-4 alcohol.

The antidepressant-like effect of trans-astaxanthin involves the serotonergic system.

The antidepressant-like effect of trans-astaxanthin, a compound present rich in algae, was evaluated through behavioral and neurochemical methods. Results showed that trans-astaxanthin treatment significantly decreased the immobility time in force swim test and tail suspension test, but did not influence locomotor activity. Trans-astaxanthin treatment did not effectively antagonize hypothermia and ptosis induced by reserpine.
