Reproductive and developmental toxicity studies detect adverse effects of prenatal or peri/postnatal exposure on maternal condition, pregnancy maintenance, embryo-fetal survival, fetal growth, structural development, and offspring reproductive or developmental endpoints; classic rat protocols generate readouts by comparing treated groups with vehicle, pair-fed, or untreated controls for implantation, resorption, fetal weight, crown-rump length, external morphology, visceral morphology, skeletal ossification, anogenital distance, nipple/areola retention, and postnatal cohort outcomes.

ROS/oxidative-stress fluorescent staining uses cell-permeant fluorogenic probes that become fluorescent after oxidation inside cells or tissues; commonly used examples include DCFH-DA/DCFDA for broad cellular oxidant detection, DHE for superoxide-related signal detection, MitoSOX for mitochondrial superoxide-related signal detection, and CellROX probes for oxidative-stress-associated fluorescence readouts. The assay detects probe oxidation rather than a single ROS species unless the probe and analysis method have been chemically validated for that species. DCFH-DA enters cells, is deacetylated by intracellular esterases to DCFH, and produces fluorescent DCF after oxidation, so the readout is used as an operational measure of total cellular oxidative stress rather than a species-specific ROS measurement. DHE and MitoSOX can report superoxide-related oxidation, but red fluorescence alone can include non-specific ethidium-like oxidation products; HPLC or optimized spectral approaches are

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

A repeated-dose oral toxicity study evaluates systemic toxic effects after daily oral exposure to a test substance for a defined period, commonly 28 days, 6 weeks, 90 days, or 13 weeks in rodent studies. The readout is generated by integrating mortality, clinical signs, body-weight change, food and water intake, functional or behavioral observations, hematology, serum biochemistry, urinalysis, organ weights, necropsy, and histopathology to identify dose-related adverse effects, target organs, and the no-observed-adverse-effect level (NOAEL).

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.

Breast cancer is a heterogeneous cancer, and it has been distinguished into four subtypes: luminal A, luminal B, HER2-positive and basal-like. Molecular mutations, epigenetic alterations, hormone exposure and immune microenvironment are related to the progression of breast cancer.

Liver histomorphometry is a quantitative histological approach used to measure structural alterations in hepatic tissue, including parenchymal loss, steatosis, fibrosis, and vascular remodeling, by combining stained tissue section analysis with stereological or computerized image-based measurements. Classical morphometric frameworks quantify volume fractions of liver compartments and fibrotic regions using systematic sampling and image analysis, enabling objective comparison of pathological changes across experimental groups. These approaches are widely applied in liver cirrhosis and fibrosis studies to reduce subjectivity in histological scoring and improve reproducibility of tissue evaluation. Recent methodological advances integrate automated image analysis and radiomics-based extraction of histological features from standard liver stains (e. g. , H&E and fibrotic stains), enabling quantitative correlation between morphometric features and fibrosis stages in non-alcoholic fatty live
