ABSTRACT
BACKGROUND:
Numerous studies have confirmed that the leucine zipper tumor suppressor (LZTS) gene family plays a vital role in modulating transcription and cell cycle control, especially in colorectal cancer. This study aimed to evaluate the potential of leucine zipper tumor suppressor family member 3 (LZTS3) as a marker for COAD.METHODS:
Bioinformatics, immunohistochemistry, and Western blotting were applied to assess the expression of LZTS3 in tissues. Gene overexpression or silencing was used to examine the biological roles of LZTS3 and validated using an in vivo nude mouse-human tumor model.RESULTS:
The results obtained in this study indicate that LZTS3 is highly expressed in COAD. RTCA, Transwell, actin stain, and in vitro transfection experiments confirmed that LZTS3 expression inhibits tumor cell proliferation and cell migration. The results obtained in the nude mouse-human tumor model are consistent with those obtained in vitro. In particular, LZTS3 may exert biological effects by targeting the NOTCH signaling pathway. Furthermore, TAGLN was demonstrated to be a downstream target of LZTS3.CONCLUSION:
This is the first study to demonstrate the important role of LZTS3 in the proliferation and migration of COAD and to shed light on the molecular mechanism underlying the tumor-suppressing role of LZTS3.Palavras-chave
