Abstract
Lead (Pb) intoxication is known to damage the proximal tubules of kidney. Autophagy and apoptosis have been shown to be involved in a variety of renal injuries, but the underlying mechanisms remain largely unknown. In this study, we constructed a mice model of Pb intoxication and validated it against lead concentrations in blood and urine. Electron microscopy revealed that Pb promoted the accumulation of autophagosomes. Subsequent immunofluorescence and western blotting revealed that Pb intoxication suppressed the autophagic flux. Next, exosomes were isolated and extracted through ultracentrifugation, and were further identified by diameter analysis and marker detection. We also demonstrated that autophagy and apoptosis were enhanced in renal cells with exosomes of Pb expose. Furthermore, the specific mechanisms were explored by RNA sequencing and it was found that several targeted genes regulated by differential exosomal miRNAs and lncRNAs. Target genes accumulated in several signaling pathways, especially the adenosine 5'-monophosphate-activated protein kinase (AMPK) signaling. We found that Pb intoxication-induced exosomes activated the AMPK signaling in renal proximal tubule cells. Furthermore, autophagy and apoptosis assays showed that GSK-690693, an AMPK inhibitor, significantly alleviated exosome-induced renal injuries by Pb intoxication. In conclusion, Pb-mediated exosome-induced autophagy and apoptosis via activating the AMPK signaling contributing to Pb-induced nephrotoxicity in renal cells.

[PMID: 35095493 PMCID: PMC8793695 DOI: 10.3389/fphar.2021.783127] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Accepted: 12/14/2021] [Indexed: 02/02/2023] Open
Abstract
Jatrorrhizine, an isoquinoline alkaloid, is a bioactive metabolite in common medicinal plants, such as Berberis vernae Schneid., Tinospora sagittata (Oliv.) Gagnep. and Coptis chinensis Franch. These plants have been used for centuries in traditional medicine for their wide-ranging pharmacological properties. This review emphasizes the latest and comprehensive information on the sources, pharmacology, pharmacokinetics and toxicity of jatrorrhizine. Studies on this alkaloid were collected from scientific internet databases, including the Web of Science, PubMed, ScienceDirect, Google Scholar, Elsevier, Springer, Wiley Online Library and Europe PMC and CNKI, using a combination of keywords involving “jatrorrhizine”, “sources”, “pharmacology,” “pharmacokinetics,” and “toxicology”. Jatrorrhizine exhibits anti-diabetic, antimicrobial, antiprotozoal, anticancer, anti-obesity and hypolipidemic properties, along with central nervous system activities and other beneficial activity. Studies of jatrorrhizine have laid the foundation for its application to the treatment of various diseases, but some issues still exist. Further investigations might emphasize 1) specific curative mechanisms of jatrorrhizine and clinical utility, 2) application prospect in the treatment of metabolic disorders, 3) comprehensive investigations of the toxicity mechanisms and 4) interactions of jatrorrhizine with other pharmaceuticals and development of derivatives.

Abstract
This study aimed to develop polymer Eudragit S100 for preparing pH-responsive liposomes-loaded betulinic acid (pH-BA-LP) to improve the therapeutic index of chemotherapy for colorectal cancer. BA-loaded liposomes were coated with Eudragit S100 by a thin film dispersion and easily scalable pH-driven method. The prepared liposomes were evaluated for size, surface morphology, entrapment efficiency, stability, in vitro drug release, and antitumor activity. In particular, pH-BA-LP showed advantages such as lower size (<100 nm), encapsulation efficiency of 90%, high stability, and stably cumulative release. By detecting the antitumor effects of pH-BA-LP in vivo, it showed that the tumor proliferation and cell migration were significantly inhibited in colorectal cancer. The pH-BA-LP also inhibited tumor growth via the regulation of Akt/TLR-mediated signalling and significantly down-regulated the expression of NFAT1 and NFAT4 proteins. It was found that pH-BA-LP can increase NK cells and CD3+ cells in tumor tissues, and the proportion of CD8+ cells in CD3+ cells was also increased, which proved that pH-BA-LP can play an antitumor effect by enhancing the autoimmunity level in tumor-bearing mice. The positive infiltration rates of CD8 and CD68 were increased and CD163 was relatively decreased by using pH-BA-LP, which proved that pH-BA-LP can regulate the immune infiltration levels in tumor-bearing mice. Therefore, the present work provides an effective method to prepare pH-responsive polymer-coated liposomes for colonic delivery with biologically active compounds.

Duan W, Chen X. Jatrorrhizine can improve nerve cell injury induced by Aβ 25-35, acting through miR-223-3p/HDAC4 axis. Am J Transl Res 2021; 13:4644-4655. [PMID: 34150044 PMCID: PMC8205821] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Accepted: 03/04/2021] [Indexed: 06/12/2023]
Abstract
OBJECTIVE The purpose of this research is to probe the mechanism of Jatrorrhizine (JAT) improving Aβ 25-35-induced nerve cell injury through the miR-223-3p/HDAC4 axis. METHODS SH-SY5Y cells were treated with Aβ 25-35 to simulate nerve injury in the pathogenesis of Alzheimer's disease (AD), and JAT-treated SH-SY5Y cells were assessed for HDAC4 and miR-223-3p. The HDAC4 and miR-223-3p levels were tested by qRT-PCR. Proliferation was determined through MTT. Apoptosis was assessed by flow cytometry, and the related indexes of oxidative stress (OS) were examined by an OS kit. RESULTS Compared with AD group, OD value increased, apoptosis rate decreased, and OS was inhibited in the AD+JAT group (all P<0.05). In SH-SY5Y cells, miR-223-3p can specifically inhibit the HDAC4 expression. The miR-223-3p expression increased and HDAC4 decreased after JAT acted on SH-SY5Y cells stimulated by Aβ 25-35 (all P<0.05). The addition of over-expression HDAC4 vector or miR-223-3p inhibitor could inhibit proliferation, and promote apoptosis and OS on the basis of JAT (all P<0.05). In addition, over-expressing miR-223-3p can suppress over-expressed HDAC4's effects on proliferation, apoptosis, and OS of SH-SY5Y cells (all P<0.05). CONCLUSION JAT can improve the nerve injury induced by Aβ 25-35 by up-regulating miR-223-3p and inhibiting the HDAC4 expression, suppress apoptosis and OS, and induce proliferation. This research further clarified the mechanism of JAT in AD.
