SQSTM1/p62 predicts prognosis and upregulates the transcription of CCND1 to promote proliferation in mantle cell lymphoma.

Mantle cell lymphoma (MCL) is a rare, highly invasive non-Hodgkin's lymphoma. The main pathogenesis of MCL is associated with the formation of the IgH/CCND1 fusion gene and nuclear overexpression of cyclin D1, which accelerates the cell cycle, leading to tumorigenesis. The prognosis with current standard chemotherapy is still unsatisfactory.

The expression of presenilin 1 enhances carcinogenesis and metastasis in gastric cancer.

Presenilin 1 (PS-1, encoded by PSEN1) is a part of the gamma- (γ-) secretase complex. Mutations in PSEN1 cause the majority of cases of familial Alzheimer's disease (FAD). Although in recent years PS-1 has been implicated as a tumor enhancer in various cancers, nothing is known regarding its role in gastric cancer (GC).
