Lipoxin A4
Based on 1 publication(s) in Google Scholar
Lipoxin A4 (LXA4), an endogenous lipoxygenase-derived eicosanoid mediator, has potent dual pro-resolving and anti-inflammatory properties. Lipoxin A4 inhibits proliferation and inflammatory cytokine/chemokine production of human epidermal keratinocytes (NHEKs) associated with the ERK1/2 and NF-kB pathways. Lipoxin A4 inhibits serum amyloid A (SAA)-mediated IL-8 release with an IC50 value of 25.74 nM.

LXA4 pretreatment (100 nM for 30 minutes) downregulates the LPS-induced secretion and expression of HMGB1 in keratinocytes[1].
Lipoxin A4 (LXA4) inhibits the expression of IL-6 and IL-8 in NHEKs[2].
Lipoxin A4 downregulates the expression of cyclin D1[2].
Lipoxin A4 also suppresses the ERK1/2 phosphorylation and NF-kB-p65 nuclear translocation of NHEKs[2].
LXA4 (100 nM; preincubation for 30 minutes)inhibits the proliferation of NHEKs with or without stimulating by LPS (10 μg/mL)[2].

-
Cell Line:Normal human epidermal keratinocytes (NHEKs)
-
Concentration:100 nM
-
Incubation Time:30 minutes.
-
Result:HMGB1 protein levels in the cytoplasm of NHEKs were induced by LPS, which were decreased after preincubation with LXA4 but decreased in the nucleus after stimulation with LPS.
-
Cell Line:Normal human epidermal keratinocytes (NHEKs)
-
Concentration:100 nM
-
Incubation Time:30 minutes
-
Result:A significant increase in proliferation of NHEKs after 7 days of stimulation with LPS (10 μg/mL) was seen. However, there was a significant decrease in the proliferation of NHEKs when pretreated with LXA4 for 30 min.

Animal Model:Rat models of non-compressive lumbar disc herniation[4]
-
Dosage:10 and 100 ng
-
Administration:Intrathecal injection; 3 days
-
Result:Alleviated the development of neuropathic pain.
Inhibited the upregulation of pro-inflammatory cytokines (TNF-a and IL-1β).
Upregulated the expression of anti-inflammatory cytokines (TGF-β1 and IL-10) and attenuated the activation of NF-κB/p65, p-ERK, p-JNK, but not p-p38.
