The overall process of literature identification, screening, eligibility assessment, and final inclusion is summarized in a PRISMA 2020-style flow diagram (Figure 2)

It is a non-hormonal approach: no IGF-1 or cortisol changes, no stimulant jitters, no appetite suppression

The signaling system that regulates SA is closely related to plant resistance [75]

In contrast, cuproptosis represents a separate copper-dependent pathway in which excess copper directly targets mitochondrial metabolism, inducing cell death through aggregated lipoylated proteins and iron-sulfur (Fe-S) cluster loss, independent of apoptotic signaling [3, 8]
