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.

Descripciòn

Lipoxin A4 (LXA4), an endogenous lipoxygenase-derived eicosanoid mediator, has potent dual pro-resolving and anti-inflammatory properties[1]. Lipoxin A4 inhibits proliferation and inflammatory cytokine/chemokine production of human epidermal keratinocytes (NHEKs) associated with the ERK1/2 and NF-kB pathways[2]. Lipoxin A4 inhibits serum amyloid A (SAA)-mediated IL-8 release with an IC50 value of 25.74 nM[3].

In Vitro

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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis[1]

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 Proliferation Assay[2]

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.
In Vivo

Lipoxin A4 (intrathecal injection; 10-100 ng; 3 days) potently alleviates radicular pain in a rat model of non-compressive lumbar disc herniation[4].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
