Dioctyl phthalate
Based on 2 publication(s) in Google Scholar
Dioctyl phthalate (DNOP) is a plasticizer. Dioctyl phthalate increases the activities of alanine aminotransferase (ALT) and alkaline phosphatase (ALP) in the liver, as well as the levels of creatinine and urea in the kidney. Exposure to Dioctyl phthalate disrupts the homeostasis of the intestinal microbial community, increases the abundance of pathogenic bacteria, and reduces the abundance of beneficial bacteria such as Lactobacillus. Dioctyl phthalate induces significant and dose-dependent inflammatory responses in the liver, spleen and kidney of mice.

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocols
-
Nephrotoxicity Study
This protocol assesses nephrotoxicity by combining functional kidney injury readouts, urinary/tissue injury biomarkers, and renal histopathology. Serum creatinine and BUN reflect impaired kidney function, while KIM-1, NGAL, clusterin, osteopontin, IL-18, cystatin C, nephrin, Oat5, urinary protein, glucose, and alkaline phosphatase have been used to detect tubular injury in cisplatin-, gentamicin-, and acetaminophen-induced nephrotoxicity models.

Mesenchymal stromal/stem cell osteogenic differentiation
Mesenchymal stromal/stem cells can be induced toward an osteoblast-like lineage in vitro by culture in osteogenic medium containing dexamethasone, ascorbic acid or ascorbate-2-phosphate, and β-glycerophosphate; the differentiation process is commonly evaluated by alkaline phosphatase activity, osteogenic marker expression, collagenous matrix formation, and calcium-rich matrix mineralization. The main readouts are alkaline phosphatase activity as an early osteogenic marker and Alizarin Red S staining as a calcium-deposit readout for mineralized extracellular matrix; Alizarin Red S can be inspected microscopically or extracted and measured colorimetrically at 405 nm.

Research Protocol for Microbiome Analysis
Microbiome analysis characterizes microbial communities in biological or environmental samples by measuring community composition, diversity, taxonomic structure, functional potential, and associations with host or environmental phenotypes. 16S rRNA gene amplicon sequencing is commonly used for bacterial and archaeal taxonomic profiling, while shotgun metagenomics provides higher taxonomic resolution and direct functional information, including microbial genes, pathways, viruses, fungi, and antimicrobial-resistance genes when sequencing depth and host-DNA contamination are adequately controlled. Microbiome results are strongly affected by sample collection, storage, DNA extraction, contamination, sequencing method, reference database, and bioinformatic pipeline; therefore, standardized protocols, negative controls, mock communities, and transparent analysis workflows are required. Unresolved issues include low-biomass contamination, compositional-data bias, inconsistent species-level c
-
Hepatotoxicity Study
This protocol evaluates hepatotoxicity using complementary in vivo mouse APAP acute liver injury and in vitro hepatocyte-based cytotoxicity readouts. In vivo APAP injury is assessed by serum ALT/AST, liver histology, hepatic glutathione, protein adducts, necrosis, inflammation, and regeneration-related endpoints. In vitro hepatotoxicity is assessed by loss of viability, leakage of ALT/AST/LDH, oxidative-stress markers, mitochondrial function, nuclear morphology, intracellular calcium, and high-content imaging endpoints.
