In this study, we aimed to determine the expression pattern of LINC00205 in retinoblastoma (RB), to identify its functions in RB progression in detail, and to reveal the underlying mechanisms. Herein, we showed that LINC00205 is highly expressed in RB tissues and cell lines. The LINC00205 upregulation correlated with adverse clinicopathological parameters and shorter overall survival in patients with RB. LINC00205 depletion decreased the proliferative, migratory, and invasive abilities; promoted the apoptosis of RB cells in vitro; and impeded the tumor growth of RB cells in vivo. Mechanism investigation revealed that LINC00205 can act as a competing endogenous RNA by sponging microRNA-665 (miR-665) in RB cells, thereby upregulating miR-665's target high-mobility group box 1 (HMGB1). Finally, rescue experiments confirmed that enhancing the miR-665-HMGB1 axis output attenuated the influence of the LINC00205 knockdown on RB cells. To sum up, the newly identified LINC00205-miR-665-HMGB1 pathway was systematically studied and may be validated as a potential target for RB diagnosis, prognosis, and therapy. Cupressus macrocarpa is a windbreak tree and is reported to have various cytotoxic effects. A natural product study on the leaves of C. macrocarpa has yielded ten secondary metabolites, including three new diterpenoids (1-3), four known diterpenoids (4-7), and three known lignans (8-10). The structures of all isolated compounds were elucidated via the interpretation of spectroscopic methods, especially 2D NMR and mass analyses. In the cytotoxic assays, compounds 1-3 and 7-10 showed inhibition effect against HepG2, MDA-MB-231, and A549 cells with IC50 values ranging from 0.004 to 19.9 μg/mL. Moreover, the anti-inflammatory assays revealed that (-)-matairesinol (8) had significant inhibito
