“…Indeed, this finding is consistent with that of a previous study showing that LY can suppress the IL-1β-induced expression of MMP-3 and MMP-13 in articular chondrocytes [55]. The present study reveals a further function of LY in addition to its known pharmacological effects, such as anti-tumour [51], antiviral [52], and anti-inflammatory [53, 54] effects.…”

“…Lycorine (LY) is the most abundant alkaloid isolated from the Amaryllidaceae family of plants [51] and can perform diverse biological functions, including anti-tumour [51], anti-viral [52] and anti-inflammatory [53, 54] functions. In addition, LY suppresses the IL-1β-induced expression of MMP-3 and MMP-13 in articular chondrocytes [55].…”

“…These data imply the possibility of phosphorylation of clock proteins by Lycoris alkaloids. Effects of Lycoris alkaloids on the protein phosphorylation has not been fully elucidated yet and it has been reported that lycorine shows the inhibition of p38 and STATs, or dephosphorylation of these proteins [34], implying that the circadian period elongation by Lycoris alkaloids may be brought by the synergic effect, enhancement of BMAL1 and other biochemical activities such as protein phosphorylation. A more precise mechanism of period elongation should be elucidated and Lycoris alkaloids will be useful tools with which to analyze the circadian mechanism.…”

“…It has recently been shown that selective inhibitors of iNOS, that reduce the release of nitric oxide in vivo, inhibited the progression of tumorigenesis in several cancers models [40,[53][54][55][56][57]. Moreover, the inhibition of lipopolysaccharide (LPS) induced NF-kB activation inhibits iNOS expression and NO production, and inhibits inflammation-mediated tumorigenesis in mouse models [58][59][60][61][62][63][64][65].…”

“…In chronic inflammation models and inflammation-related tumorigenesis, iNOS may be persistently stimulated by cytokines and NF-kB activation in the tumor microenvironment. iNOS/NO signaling can also induce cyclo-oxygenase-2 (COX-2), which is another link between inflammation and cancer [59,70]. In view of the diverse effects of iNOS-produced NO, it is important to determine how cells regulate their iNOS/NO system.…”
