Biomarkers offer certain values for diagnosis, treatment efficacy monitoring, or novel therapeutic approaches development for diseases. Exportin 1 (XPO1) represents an exciting field located at the intersection between pathophysiology, diagnosis, and treatment of B cell malignancies. Creative Biolabs has developed a full suite of research services for XPO1 to evaluate its expression and function.
Introduction of XPO1
XPO1, also known as Chromosome Region Maintenance 1 (CRM1), is a pivotal nuclear transport protein. It mediates the movement of over 200 cargo molecules, including tumor suppressors, from the nucleus to the cytoplasm. This selective transport is critical for cellular homeostasis. Beyond nuclear export, XPO1 also maintains chromosome integrity and is involved in microtubule nucleation at the kinetochore, highlighting its multifaceted importance in cellular biology.

Dysregulation of XPO1 is a significant factor in numerous human malignancies. For decades, XPO1 dysfunction has been regarded as a diagnostic and prognostic marker and a promising anti-cancer therapeutic target. For example, in B-cell malignancies like mantle cell lymphoma (MCL), XPO1 overexpression drives uncontrolled cell proliferation and compromises chromosomal stability. Furthermore, the specific somatic mutation XPO1E571K directly contributes to carcinogenesis and is quantifiable in tumor tissue and plasma cell-free DNA using highly sensitive techniques like digital PCR and next-generation sequencing (NGS), providing new avenues for patient stratification and personalized medicine.

Service Workflow
Our XPO1 analysis services follow a clear, step-by-step workflow designed for optimal project execution and timely data delivery.
01Initial Consultation
The process begins with a detailed consultation to understand your specific research goals, technical requirements, and project scope.
02Sample Submission
Clients provide their starting materials, which may include cell lines, purified DNA/RNA, or clinical samples such as tissue biopsies or plasma.
03Assay Preparation and Analysis
Our expert team prepares and runs the necessary assays. This can range from high-throughput compound screens to targeted XPO1 mutation analysis using digital PCR or NGS.
04Quality Control
Throughout the analysis, we maintain strict quality control to guarantee the accuracy and reliability of all data generated.
05Final Report Delivery
We deliver a comprehensive report that includes all raw data, detailed methodologies, and a professional interpretation of the results, empowering your team to make informed decisions for your drug development pipeline.
Applications
Patient Stratification and Diagnosis
Analysis of XPO1 expression and mutation status in patient samples can serve as a powerful tool for diagnosing specific cancer subtypes and stratifying patients for clinical trials. This allows for the selection of individuals most likely to benefit from XPO1-targeting therapies.
Therapeutic Target Validation
Our services provide critical data for validating XPO1 as a therapeutic target in novel disease models. By correlating XPO1 dysregulation with disease phenotype, researchers can build a strong case for developing and testing new selective inhibitors of nuclear export (SINEs).
Monitoring Treatment Response
Longitudinal monitoring of XPO1 expression and mutation load in liquid biopsy samples provides a non-invasive method for tracking disease progression and evaluating the efficacy of anti-cancer therapies. A decrease in the mutant XPO1E571K allele frequency, for example, could indicate a positive response to treatment.
Novel Drug Discovery
The ability to screen thousands of compounds against XPO1 provides a clear advantage in drug discovery. Our high-throughput screening assays help researchers to efficiently identify and optimize lead compounds for further development.
