Abstract
CONTEXT Diabetic kidney disease (DKD) is a prominent complication arising from diabetic microangiopathy, and its prevalence and renal impact have placed it as the primary cause of end-stage renal disease. Traditional Chinese Medicine (TCM) has the distinct advantage of multifaceted and multilevel therapeutic attributes that show efficacy in improving clinical symptoms, reducing proteinuria, protecting renal function, and slowing DKD progression. Over recent decades, extensive research has explored the mechanisms of TCM for preventing and managing DKD, with substantial studies that endorse the therapeutic benefits of TCM compounds and single agents in the medical intervention of DKD. OBJECTIVE This review lays the foundation for future evidence-based research efforts and provide a reference point for DKD investigation. METHODS The relevant literature published in Chinese and English up to 30 June 2023, was sourced from PubMed, Cochrane Library, VIP Database for Chinese Technical Periodicals (VIP), Wanfang Data, CNKI, and China Biology Medicine disc (CBM). The process involved examining and summarizing research on TCM laboratory tests and clinical randomized controlled trials for DKD treatment. RESULTS AND CONCLUSIONS The TCM intervention has shown the potential to inhibit the expression of inflammatory cytokines and various growth factors, lower blood glucose levels, and significantly affect insulin resistance, lipid metabolism, and improved renal function. Furthermore, the efficacy of TCM can be optimized by tailoring personalized treatment regimens based on the unique profiles of individual patients. We anticipate further rigorous and comprehensive clinical and foundational investigations into the mechanisms underlying the role of TCM in treating DKD.

Zhang Q, Lu B. The mRNA and microRNA Landscape of the Blastema Niche in Regenerating Newt Limbs. Int J Mol Sci 2024; 25:9225.

Abstract
Newts are excellent vertebrate models for investigating tissue regeneration due to their remarkable regenerative capabilities. To investigate the mRNA and microRNAs (miRNAs) profiles within the blastema niche of regenerating newt limbs, we amputated the limbs of Chinese fire belly newts (Cynops orientalis) and conducted comprehensive analyses of the transcriptome and microRNA profiles at five distinct time points post-amputation (0 hours, 1 day, 5 days 10 days and 20 days). We identified 24 significantly differentially expressed (DE) genes and 20 significantly DE miRNAs. Utilizing weighted gene co-expression network analysis (WGCNA) and gene ontology (GO) enrichment analysis, we identified four genes likely to playing crucial roles in the early stages of limb regeneration: Cemip, Rhou, Gpd2 and Pcna. Moreover, mRNA-miRNA integration analysis uncovered seven human miRNAs (miR-19b-1, miR-19b-2, miR-21-5p, miR-127-5p, miR-150-5p, miR-194-5p, and miR-210-5p) may regulate the expression of these four key genes. The temporal expression patterns of these key genes and miRNAs further validated the robustness of the identified mRNA-miRNA landscape. Our study successfully identified candidate key genes and elucidated a portion of the genetic regulatory mechanisms involved in newt limb regeneration. These findings offer valuable insights for further exploration of the intricate processes of tissue regeneration.

Biochem Pharmacol 2024; 225:116278. [PMID: 38740223 DOI: 10.1016/j.bcp.2024.116278] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2024] [Revised: 04/25/2024] [Accepted: 05/10/2024] [Indexed: 05/16/2024]
Abstract
Calcium (Ca2+) acts as a second messenger and constitutes a complex and large information exchange system between the endoplasmic reticulum (ER) and mitochondria; this process is involved in various life activities, such as energy metabolism, cell proliferation and apoptosis. Increasing evidence has suggested that alterations in Ca2+ crosstalk between the ER and mitochondria, including alterations in ER and mitochondrial Ca2+ channels and related Ca2+ regulatory proteins, such as sarco/endoplasmic reticulum Ca2+-ATPase (SERCA), inositol 1,4,5-trisphosphate receptor (IP3R), and calnexin (CNX), are closely associated with the development of kidney disease. Therapies targeting intracellular Ca2+ signaling have emerged as an emerging field in the treatment of renal diseases. In this review, we focused on recent advances in Ca2+ signaling, ER and mitochondrial Ca2+ monitoring methods and Ca2+ homeostasis in the development of renal diseases and sought to identify new targets and insights for the treatment of renal diseases by targeting Ca2+ channels or related Ca2+ regulatory proteins.

Endoplasmic Reticulum Stress in Renal Cell Carcinoma. Int J Mol Sci 2023; 24:ijms24054914. [PMID: 36902344 PMCID: PMC10003093 DOI: 10.3390/ijms24054914] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Revised: 02/22/2023] [Accepted: 02/23/2023] [Indexed: 03/08/2023] Open
Abstract
The endoplasmic reticulum is an organelle exerting crucial functions in protein production, metabolism homeostasis and cell signaling. Endoplasmic reticulum stress occurs when cells are damaged and the capacity of this organelle to perform its normal functions is reduced. Subsequently, specific signaling cascades, together forming the so-called unfolded protein response, are activated and deeply impact cell fate. In normal renal cells, these molecular pathways strive to either resolve cell injury or activate cell death, depending on the extent of cell damage. Therefore, the activation of the endoplasmic reticulum stress pathway was suggested as an interesting therapeutic strategy for pathologies such as cancer. However, renal cancer cells are known to hijack these stress mechanisms and exploit them to their advantage in order to promote their survival through rewiring of their metabolism, activation of oxidative stress responses, autophagy, inhibition of apoptosis and senescence. Recent data strongly suggest that a certain threshold of endoplasmic reticulum stress activation needs to be attained in cancer cells in order to shift endoplasmic reticulum stress responses from a pro-survival to a pro-apoptotic outcome. Several endoplasmic reticulum stress pharmacological modulators of interest for therapeutic purposes are already available, but only a handful were tested in the case of renal carcinoma, and their effects in an in vivo setting remain poorly known. This review discusses the relevance of endoplasmic reticulum stress activation or suppression in renal cancer cell progression and the therapeutic potential of targeting this cellular process for this cancer.

Abstract
Despite the development of many antibiotics, excessive inflammation caused by endotoxins is still a subject of interest to biomedical researchers. The hyper-inflammatory response of macrophages activated by endotoxins is an important topic in the development of natural product-based anti-inflammatory drugs. Conioselinum tenuissimum, a perennial herb of the family Apiaceae, contains levistolide A, demethylsuberosin, and fraxetin. One of the synonyms of Conioselinum tenuissimum is Angelica tenuissima. The objective of this study was to determine the effects of Conioselinumtenuissimum root water extract (AT) on the hyper-inflammatory responses of macrophages activated by endotoxin (lipopolysaccharide; LPS) and the mechanisms involved in such effects. Levels of cytokines, nitric oxide (NO), hydrogen peroxide, and cytosolic calcium in LPS-activated RAW 264.7 murine macrophages were evaluated by the multiplex cytokine assay (MCA), Griess reagent assay (GRA), dihydrorhodamine 123 assay (DHR), and Fluo-4 calcium assay (FCA), respectively. Additionally, real-time PCR and the flow cytometry assay (FLA) was performed to determine the effects of AT on LPS-activated RAW 264.7. Data from MCA, GRA, DHR, and FCA revealed that AT lowered levels of IL-6, MCP-1, TNF-α, G-CSF, GM-CSF, VEGF, M-CSF, LIF, LIX, MIP-1α, MIP-1β, MIP-2, RANTES, IP-10, NO, hydrogen peroxide, and calcium in LPS-activated RAW 264.7. Real-time PCR results revealed that AT significantly lowered mRNA expression levels of inflammatory genes such as Chop, Nos2, c-Jun, Stat1, Stat3, c-Fos, Camk2a, Ptgs2, Fas, and Jak2. FLA showed that AT significantly reduced phosphorylation levels of P38 MAPK and STAT3 in LPS-activated RAW 264.7. These results indicate that AT can exert anti-inflammatory effects in LPS-activated macrophages via the calcium–STAT3 pathway.

Wogonin inhibits inflammation and apoptosis through STAT3 signal pathway to promote the recovery of spinal cord injury. Brain Res 2022; 1782:147843. [PMID: 35202619 DOI: 10.1016/j.brainres.2022.147843] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Revised: 02/15/2022] [Accepted: 02/17/2022] [Indexed: 01/29/2023]
Abstract
Spinal cord injury (SCI) is a complex central traumatic disease. STAT3 signal transduction pathway plays an important role in SCI. Wogonin has been reported to exhibit neuroprotection. However, the molecular mechanism of its potential therapeutic effect after SCI remains unclear. In this study, rats were divided into the following groups: Sham; SCI; SCI + wogonin; and SCI + wogonin + colivelin (Colivelin is an effective activator of the STAT3 pathway). Motor function was evaluated by Basso Beattie Bresnahan (BBB) score. Histomorphological changes in the spinal cords were observed by Hematoxylin-eosin (HE) staining and Nissl staining. Western blot, Transferase-mediated dUTP-biotin nick end labeling (TUNEL) staining, and immunofluorescence were used to detect changes in the neuronal inflammation, apoptosis, and STAT3 signal pathway. Western blot and immunofluorescence techniques were also performed to detect the regulatory effect and the underlying mechanism of wogonin on the inflammation and apoptosis of PC12 cells. Experimental results in vivo and in vitro showed that wogonin could promote the recovery of motor function, improve the histopathological morphology, inhibit the activation of the STAT3 signal pathway, and reduce the neuronal inflammation and apoptosis in the rats with SCI. Activation of the STAT3 signal pathway by colivelin reversed the therapeutic effect of wogonin. Therefore, wogonin could inhibit inflammation and apoptosis by inhibiting the STAT3 signal pathway and promote the functional recovery of rats with SCI.
