AZ14145845
Based on 1 Customer Validation
AZ14145845 is an orally active dual-target type 1½ kinase inhibitor of Mer/Axl, which inhibits Mer kinase (pIC50 = 9.0) and Axl kinase (pIC50 = 7.9) with high selectivity over Flt3 and Tyro3. AZ14145845 suppresses Mer- and Axl-dependent proliferation in Ba/F3 cells and inhibits efferocytosis in macrophages. AZ14145845 reduces the phagocytosis of photoreceptor outer segments by polarized human retinal epithelial cells. AZ14145845 inhibits tumor growth and induces tumor regression in vivo, and its combination with anti-PD1 antibody and ionizing radiation improves the survival rate of mice with colorectal cancer. AZ14145845 causes retinal degeneration in mice, with pathological changes similar to those in MERTK loss-of-function models. AZ14145845 can be used in studies related to retinal degeneration, lymphoma and colorectal cancer.

Phagocytosis Functional Assay
A phagocytosis functional assay measures the ability of phagocytic cells, such as neutrophils, macrophages, monocytes, or microglia/macrophages, to bind and internalize particulate targets including bacteria, yeast particles, beads, or myelin particles. Fluorescent flow-cytometry assays detect target uptake as fluorescence associated with gated phagocytes, while pH-sensitive dyes such as pHrodo increase signal in acidic phagosomal compartments and therefore preferentially report internalized particles rather than particles remaining outside the cell. Microscopy or high-content imaging can be used to confirm intracellular localization and, in some protocols, to follow uptake kinetics.

Patient-Derived Xenograft (PDX)
Patient-derived xenograft (PDX) models are generated by engrafting primary human tumor tissue directly into immunodeficient mice, allowing in vivo propagation of patient tumor biology without initial in vitro adaptation. These models are used to preserve key histopathological and molecular characteristics of the original tumor and enable assessment of tumor growth dynamics and therapeutic response in a living organism. The biological readout is tumor engraftment and subsequent growth in the murine host, which reflects the ability of human tumor cells to survive, vascularize, and expand in an immunocompromised microenvironment.
-
Patient-Derived Orthotopic Xenograft (PDOX)
Patient-derived orthotopic xenograft (PDOX) modeling implants fresh patient tumor tissue or patient-derived tumor cells into the anatomically corresponding organ or tissue site of immunodeficient mice, usually by surgical orthotopic implantation, to preserve patient tumor histology, local microenvironmental context, invasion, metastatic behavior, and treatment-response features better than subcutaneous implantation. PDOX readouts include tumor engraftment, orthotopic tumor growth, local invasion, metastasis, recurrence after resection, histologic similarity to the donor tumor, biomarker retention, molecular concordance, survival, and response or resistance to therapy. PDOX models are used for preclinical drug testing and individualized therapy evaluation, but engraftment success varies by tumor type and specimen quality.
-
Subcutaneous Cell-Line-Derived Xenograft
Subcutaneous cell-line-derived xenograft (CDX) models are established by implanting cultured human cancer cell lines into immunodeficient mice, where the injected cells form localized tumors that can be monitored in vivo as a measure of tumorigenic potential, growth kinetics, and treatment response. These models are widely used in oncology research because they allow reproducible tumor formation and enable comparative assessment of tumor growth between different cell lines or genetic manipulations in a controlled in vivo microenvironment. Subcutaneous implantation of cancer cells in immunodeficient mice is a standard approach for evaluating tumor growth behavior and therapeutic response across multiple cancer types, including prostate, esophageal, pancreatic, and colon cancer models.
-
Orthotopic Cell-Line Xenograft
Orthotopic cell-line xenograft models involve implantation of human cancer cell lines into the anatomically corresponding organ of immunodeficient mice to reproduce tumor growth within a native microenvironment, enabling more clinically relevant tumor behavior compared with subcutaneous models. These models are widely used because orthotopic placement better recapitulates tumor progression, including invasion and metastatic spread, which are often underrepresented in heterotopic implantation systems. Compared with conventional xenografts, orthotopic implantation is described as more technically complex but provides improved simulation of tumor-microenvironment interactions and metastatic behavior, making it particularly valuable for translational oncology research. Surgical orthotopic implantation approaches have been emphasized as enabling faithful reproduction of clinical cancer features, including metastasis and disease progression patterns that align with the tumor’s organ of origi

Cell Viability Determination by MTT Colorimetric Assay
The following protocol uses the MTT colorimetric assay as a classic literature-established method for assessing cell viability/metabolic activity in cultured mammalian cells. MTT[3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] is reduced by metabolically active cells to a colored formazan product; the amount of formazan is quantified spectrophotometrically and provides an indirect measure of metabolically active viable cells. Importantly, MTT reduction reflects cellular oxidoreductase/metabolic activity rather than an absolute direct count of living cells, so changes in cellular metabolism can alter the signal independently of cell number.
