The document concludes that careful design of genetic fate mapping experiments is crucial for accurate cell lineage tracing in mice.
research A review for cell-based screening methods in drug discovery
Cell-based screening methods are useful and cost-effective for drug discovery but have pros and cons.
research An isotope dilution-liquid chromatography-tandem mass spectrometry-based candidate reference measurement procedure for the quantification of dehydroepiandrosterone sulfate in human serum and plasma
A new method accurately measures DHEAS in blood, improving on current tests.
research Colorimetric assay for γ-glutamyl transpeptidase
The document concludes that measuring γ-glutamyl transpeptidase activity is more accurate with a higher substrate concentration and using diluted acetic acid to stop the reaction.
research 778 Designing and utilizing a c-Rel specific bioassay in drug repurposing screen for HNSCC
A new test helps find drugs to treat head and neck cancer by targeting c-Rel.
research Enzyme-linked immunosorbent assays for doping control of 5α-reductase inhibitors finasteride and dutasteride
New tests detect finasteride and dutasteride in urine quickly and easily.
research Multiple readout assay for hormonal (androgenic and antiandrogenic) and cytotoxic activity of plant and fungal extracts based on differential prostate cancer cell line behavior
The study created a test that found hormonal and toxic effects in plant and fungal extracts using prostate cancer cells.
research Screen steroid 5 alpha-reductase inhibitors in vitro by high performance liquid chromatography
The method is quick and effective for testing steroid 5 alpha-reductase inhibitors.
research An isotope dilution-liquid chromatography-tandem mass spectrometry-based candidate reference measurement procedure for the quantification of 5-alpha-dihydrotestosterone in human serum and plasma
The procedure accurately measures 5-alpha-dihydrotestosterone in blood, useful for standard tests.
research Analysis of Gene Expression in Isolated Single Hair Follicles: An Approach Using Semiquantitative Reverse-Transcriptase—Polymerase Chain Reaction
Researchers developed a new way to measure gene activity in single hair follicles and found that a specific gene's activity changes with different amounts and times of treatment.
research Visualization of individual cell division history in complex tissues
The tool iCOUNT helps understand how stem cells divide and affect tissue development and repair.
research Sensitive Quantitative In Vivo Assay for Evaluating the Effects of Biomolecules on Hair Growth and Coloring Using Direct Microinjections into Mouse Whisker Follicles
The new "whisker follicle microinjection assay" can test how different biomolecules affect hair growth and color.
research Skin toxicity determined in vitro by three-dimensional, native-state histoculture.
This model can replace animal testing for quick, cost-effective skin toxicity tests.
research A Sensitive Assay for the Enzyme Activity in Hair Follicles and Epidermis that Catalyses the Peptidyl-Arginine-Citrulline Post-translational Modification
A more sensitive assay was developed to detect enzyme activity converting arginine to citrulline in hair follicles.
research Development of a Liquid Chromatography/Mass Spectrometry-Based Inhibition Assay for the Screening of Steroid 5-α Reductase in Human and Fish Cell Lines
A new method was created to test the effectiveness of Dihydrotestosterone (DHT) inhibitors, like finasteride and dutasteride, in human and fish cells. The results showed fish cells are more sensitive to these treatments, and dutasteride works better than finasteride in all tested cells.
research Protein Microarrays
Protein microarrays are highly sensitive tools useful for disease diagnosis and studying proteins.
research Assessment of replication rates of human keratinocytes in engineered skin substitutes grafted to athymic mice
Regulating keratinocyte growth in engineered skin can improve wound healing.
