Mortality rates are significantly impacted by ischemic stroke, for which therapeutic options remain constrained. The Chinese Pharmacopoeia 2020 has integrated Dengzhan Shengmai capsule (DZSM), which has become a common remedy for ischemic stroke. Nevertheless, the complete mechanism of action of DZSM in treating ischemic stroke is not fully understood.
This study's examination of the mechanism of DZSM's action on ischemic stroke incorporated both RNA sequencing (RNA-seq) and single-cell RNA sequencing (scRNA-seq).
The rats were divided into six distinct groups by random assignment: Sham, I/R (water), I/R+DZSM-L (0.01134g/kg), I/R+DZSM-H (0.04536g/kg), I/R+NMDP (20mg/kg), and I/R+Ginaton (20mg/kg). A 5-day drug administration protocol was applied to the rats, after which they incurred ischemic brain damage due to middle cerebral artery occlusion (MCAO). maternally-acquired immunity The neuroprotective effect was measured through multiple methods: infraction rate, neurological deficit scores, regional cerebral blood flow (rCBF), hematoxylin and eosin (H&E) staining, and Nissl staining. Employing RNA-seq and single-cell RNA-seq, the key biological pathways and target molecules of DZSM in treating cerebral ischemia were identified. The enzyme-linked immunosorbent assay (ELISA) and immunofluorescence (IF) staining served as the crucial tools for investigating the essential biological processes and central targets of DZSM in ischemic stroke.
DZSM administration effectively lowered the infarction rate and scores reflecting Zea Longa, Garcia JH, and effectively improved the reduction in regional cerebral blood flow (rCBF). The neuronal damage was reduced thanks to the increase in both neuronal and Nissl bodies density levels. RNA-seq analysis showed that the molecule DZSM is implicated in both the inflammatory response and apoptotic pathways. Validation of ELISA and IF staining procedures confirmed that DZSM significantly reduced the expression of IL-6, IL-1, TNF-α, ICAM-1, IBA-1, MMP9, and cleaved caspase-3 in MCAO-affected rats. Eight key targets in neurons, including HSPB1, SPP1, MT2A, GFAP, IFITM3, VIM, CRIP1, and GPD1, were identified using scRNA-seq. Experimental validation confirmed that DZSM caused a decrease in the expression levels of both VIM and IFITM3 in these neurons.
DZSM's neuroprotective effect on ischemia stroke is demonstrated in our study, with VIM and IFITM3 identified as vital neuronal targets within the mechanism of DZSM action in countering MCAO-induced ischemia-reperfusion injury.
Our research underscores DZSM's neuroprotective capability against stroke caused by ischemia, and VIM and IFITM3 have been identified as vital neuronal targets, enabling DZSM's neuroprotection against middle cerebral artery occlusion-induced ischemia/reperfusion injury.
In traditional Chinese medicine, Chinese Ecliptae herba (Eclipta prostrata (L.) L.) is primarily employed to nourish the kidneys, thereby fortifying the bones. In vivo and in vitro studies of Ecliptae herba extract have corroborated the traditional medicinal use, revealing its anti-osteoporotic effect and stimulation of osteoblast growth and activity. The molecular process through which Ecliptae herba affects osteoblast differentiation from bone marrow mesenchymal stem cells (BMSCs), the cells that precede osteoblasts, is not yet fully understood.
Epigenetic modification of mRNA, specifically N6-methyladenosine (m6A), potentially plays a pivotal role in the stimulation of osteoblast differentiation, thereby offering a possible treatment strategy for osteoporosis. To determine how Eclipate herba, especially its wedelolactone component, affects m6A modification in the creation of osteoblasts from bone marrow stem cells, this research was performed.
Alkaline phosphatase (ALP) and Alizarin Red S (ARS) staining was employed to measure osteoblastogenesis in bone marrow-derived mesenchymal stem cells (BMSCs). Western blot analysis and quantitative real-time PCR were carried out. In order to characterize m6A methylation, the method of RNA sequencing was used. A lentiviral shRNA strategy was implemented for the stable reduction of METTL3.
After nine days of ethyl acetate extract of Ecliptae herba (MHL) treatment, BMSCs displayed an increment in alkaline phosphatase (ALP) activity and ossification, compared to cells treated with osteogenic medium (OS). Following MHL treatment, a marked increase in the expression of methyltransferases METTL3 and METTL14 was observed, whereas WTAP expression exhibited no alteration. Lowering METTL3 levels produced a diminished response of MHL-stimulated ALP activity, a reduction in bone ossification, and decreased mRNA levels of Osterix and Osteocalcin, which are associated with bone formation. Following a nine-day MHL treatment, BMSC exhibited an increase in the m6A level. Analysis of RNA sequencing data showed that MHL treatment resulted in alterations in the mRNA m6A modification of genes crucial for osteoblast formation. Analysis of KEGG pathways, including HIF-1, PI3K/Akt, and Hippo signaling pathways, demonstrated an association with m6A modification. The upregulation of m6A-modified genes, HIF-1, VEGF-A, and RASSF1, brought about by MHL, was counteracted by a subsequent knockdown of METTL3. Following treatment with wedelolactone, a component of MHL, there was a noticeable upregulation of METTL3.
These observations suggest an innovative mechanism of MHL and wedelolactone's influence on osteoblastogenesis, featuring METTL3-mediated m6A methylation and thereby contributing to increased osteoblast formation.
The findings indicated a novel mechanism of MHL and wedelolactone on osteoblastogenesis, wherein METTL3-mediated m6A methylation plays a role and thereby promotes osteoblastogenesis.
Predicting clinical success in patients with pancreato-biliary and gynecological adenocarcinomas necessitates the development of enhanced diagnostic instruments. Through analysis of the transcriptome, mesenchymal-like subtypes with possible prognostic significance have been recognized in these cancers. This systematic review encompasses studies focused on molecular subtyping, summarizing biological and clinical aspects of subtypes across various tissue sources, with the objective of potentially improving both classification and prognostic accuracy. A systematic search of PubMed and Embase was undertaken to find original research articles describing potential mRNA-based subtypes of mesenchymal-like nature in pancreato-biliary or gynecological adenocarcinomas. The research excluded any studies that solely employed supervised clustering techniques. A compilation of forty-four studies investigated cholangiocarcinomas, gallbladder, ampullary, pancreatic, ovarian, and endometrial adenocarcinomas. Overlap in molecular and clinical characteristics distinguished mesenchymal-like subtypes across all adenocarcinomas. Among various strategies, microdissection procedures were more successful in recognizing subtypes correlated with prognosis. To summarize, a commonality in biological and clinical characteristics exists among the molecular subtypes of pancreato-biliary and gynecological adenocarcinomas. It is imperative that future research on biliary and gynecological adenocarcinomas isolate and analyze the distinct stromal and epithelial signaling.
