Reduced IQGAP2 promotes esophageal squamous cell carcinoma by regulating MEK/ERK MAPK pathway.

Reduced IQGAP2 expression promotes ESCC cell proliferation by activating the MEK/ERK MAPK pathway, with a significant decrease observed in tumor tissues from patients.

• Why it matters: Understanding the role of IQGAP2 in ESCC is crucial because its tumor-suppressing function could lead to new therapeutic strategies for this aggressive cancer.
• What they did: The study analyzed IQGAP2 levels in 236 ESCC patient samples and manipulated its expression in EC9706 cell lines through lentiviral transfection, assessing effects on cell growth and pathway activation.
• The result: Findings show that decreasing IQGAP2 enhances tumor cell proliferation via MEK/ERK pathway activation, positioning IQGAP2 as a promising target for ESCC treatment development.
