LC3B-II is a lipidated form of LC3B that is widely used as a marker for autophagy.
-Several studies have reported that higher levels of LC3B-II correlate with more aggressive tumor behavior.
-Prognostic Implication: Increased LC3B-II expression is often associated with poorer prognosis, including reduced overall survival and disease‐free survival. This may reflect a role for autophagy in tumor cell survival under stress.
-Dual Role of Autophagy: Autophagy (and therefore LC3B-II expression) may act as both a tumor suppressor and a tumor promoter depending on the tumor type, stage, and microenvironment.
