Since the removal of lipids is crucial for transparency and efficient antibody staining throughout the tissue, especially for microscopy and imaging, it is a harmful process that can cause the loss of important biological molecules such as proteins. The FACT technique overcomes this by chemically bonding the membrane and intracellular proteins with the extracellular matrix, creating a massive 3D hydrogel matrix and providing structural support to fortify the tissue during processing. Compared to other acrylamide-based techniques, the FACT technique requires less labor and harmful chemicals and is therefore considered a more suitable option. In this study, we describe the complete FACT protocol for antibody staining and imaging of whole-cleared tissues while preserving structure and improving image quality. The protocol includes tissue perfusion, fixation, clearing, antibody staining, refractive index matching (RIM) (), microscopy, and imaging. The timing for each step varies depending on the size, weight, and type of tissue, as well as the type of immunostaining. We provide an example of the FACT protocol using mouse brain tissue, which demonstrates its suitability for molecular interrogation analysis of large tissues. The FACT technique has been successfully performed on different types of tissues, making it a favorable choice for a variety of applications.</p>","PeriodicalId":15966,"journal":{"name":"Journal of Histotechnology","volume":" ","pages":"126-142"},"PeriodicalIF":0.6,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140944901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The discomfort and reduced motion associated with osteoarthritis have a significant impact on quality of life, and there is no known solution. Runt-related transcription factor 1(Runx1) has been shown to play a protective role in the development of osteoarthritis by promoting chondrogenesis. We had created models of ageing mice with osteoarthritis by anterior cruciate ligament transection (ACLT) and analyzed the effects of intra-articular injection of adeno-associated virus/Runx1 (AAV/Runx1) on the models. The results showed that the AAV/Runx1-group maintained better articular cartilage integrity and retained more proteoglycan than the OA group after injection of AAV-Runx1. The markers related to pathological changes in cartilage were downregulated, while the markers related to physiological changes in cartilage were upregulated. This suggests that Runx1 may impede OA progression on the knee joint of ageing mice, potentially playing a protective role in OA and becoming a probable treatment target for osteoarthritis among ageing patients in the future.</p>","PeriodicalId":15966,"journal":{"name":"Journal of Histotechnology","volume":" ","pages":"57-67"},"PeriodicalIF":1.1,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"107591455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current investigation focused on the renal protective effect of GW1929, an agonist for peroxisome proliferator-activated receptors gamma (PPARγ), on cisplatin-induced kidney injury. HK2 cells treated with 20 μM cisplatin and C57BL/6 mice injected with 20 mg/kg cisplatin were used as the cell model and animal model for acute kidney injury. HK2 cell viability after cisplatin or GW1929 (0-80 μM) treatment was tested using methyl thiazolyl tetrazolium assays. Flow cytometry analysis and TUNEL assays were used to measure cell apoptosis. Intracellular reactive oxygen species (ROS) level was measured through fluorescence intensities. Levels of blood urea nitrogen (BUN) and serum creatinine (SCr) were measured to evaluate the renal function of mice. For renal morphology observation and cell apoptosis assessment <i>in vivo</i>, hematoxylin-eosin staining and TUNEL assays were conducted. The concentrations of oxidative stress markers in renal samples were measured using colorimetric tests. It was found that GW1929 dose-dependently enhanced protein levels of PPARγ, PGC-1α and TFEB in HK2 cells. Meanwhile, intracellular ROS overproduction, the decrease in cell viability and excessive cell apoptosis mediated by cisplatin were reversed by GW1929.
