背景信息

TACSTD2 encodes a transmembrane glycoprotein Trop2, that is overexpressed in most carcinomas where it has been associated with cancer cell plasticity, tumor growth, metastasis and prognosis. In humans, congenital mutations of TACSTD2 cause a gelatinous drop-like corneal disease (GDLD), a rare autosomal recessive disease characterized by the development of bilateral corneal amyloidosis and eventually blindness.Overexpression of TROP2/TACSTD2 has been shown to confer a poor prognosis, notably among patients with gynecologic or gastrointestinal tumors. TROP2/TACSTD2 has also been shown to have some impact on the tumor immune microenvironment and may modulate immunotherapy response. In cervical cancer, TROP2 levels were associated with increased intratumoral tumor-infiltrating lymphocytes and programmed cell death-ligand 1 (PD-L1) expression.Conversely, TROP2/TACSTD2-high tumors had lower gene expression of immune cell markers in breast and non–small cell lung cancer and were independently associated with poor response to immune checkpoint inhibitors (ICIs).
