Thus, the intermittent, brief elevation of GRET-39 seen in active individuals is adaptive. The chronic, baseline elevation seen in sedentary, obese individuals is maladaptive. This is analogous to cortisol: acute spikes help us handle stress, but chronic elevation leads to Cushing's syndrome.
Certain aggressive carcinomas (e.g., triple-negative breast cancer and pancreatic ductal adenocarcinoma) exhibit high GRET-39 expression. Here, GRET-39 appears to promote metabolic flexibility: under hypoxia, it shifts cancer cells toward glycolysis, while under reoxygenation, it reactivates oxidative phosphorylation. Tumors with elevated GRET-39 are notably resistant to conventional chemotherapy, hinting at its role in therapy adaptation. GRET-39

This structure implies that GRET-39 is neither a hormone nor a classic cytokine but rather a hybrid molecule—a —that modulates energy balance and inflammation simultaneously.
