Table 9: _Cont._impact their response to inflammation by triggering mechanisms that raise HDL levels and function [32], while also influencing cellular lipid signaling pathways associated with PAF activity, offering protection against thrombo-inflammatory manifestations implicated in numerous diseases [24]. In addition, other studies support that plant-derived glycolipids such as DGDG, MGDG and SQDG exhibit significant anti-tumor properties through diverse mechanisms of action. These compounds have been shown to suppress tumor growth by inhibiting angiogenesis and the expression of cell proliferation markers, such as KI-67, proliferating cell nuclear antigen (PCNA) and Cyclin E [33]. Additionally, SQDG demonstrated selective inhibition of human cancer cell proliferation without affecting other DNA metabolic enzymes, effectively halting the cell cycle at the G1 phase and inducing apoptosis in HeLa cells, accompanied by enhanced tumor necrosis in vivo [34]. Aside from that, SQDG showed potent inhibition of SNU-1 gastric cancer cells, by reduction of proliferation and the induction of apoptosis or tumor necrosis [35].
