More and More OR Pubs

Potent, Proven and Frequently Published

Many labs have used our Opioid Receptor antibodies over the past 10+ years. We are grateful for the many publications and testimonals referencing successful use of these antibodies.

Figure: MOR in primary sensory neuron and its terminals were decreased in neuropathic mice. (A, B) Western blot shows that MOR protein were markedly decreased in sciatic nerve (A) and hindpaw skin (B) on day 7 after nerve injury when compared with sham-operated mice. The ratio of MOR/GAPDH in sham mice was set at 1 for quantifications. Zhou et al. Molecular Pain 2014, 10:51 http://www.molecularpain.com/content/10/1/51

We will continue to post information on our ORs.

Opioid Receptor Antibodies Trifecta

This publication proposes a role for opioid receptors in treating cancers. It also references use of our μ, δ, and κ opioid receptor antibodies.

Kohei Yamamizu1, Sadayoshi Furuta, Shiori Katayama, Michiko Narita, Naoko Kuzumaki, Satoshi Imai, Hiroshi Nagase, Tsutomu Suzuki, Minoru Narita, and Jun K. Yamashita. The κ opioid system regulates endothelial cell differentiation and pathfinding in vascular development. Blood July 21, 2011 vol. 118 no. 3 775-785.

Highlights: The opioid system is, thus, a new regulator of vascular development that simultaneously modifies 2 distinct vascular properties, EC differentiation and vascular pathfinding. We confirmed that KOR, but not MOR, was highly expressed in various ECs such as HUVECs (data not shown), suggesting that KOR agonists could directly act on tumor ECs to suppress VEGF receptor expression, similar to the effects observed in embryonic ECs. If so, a combination therapy including an MOR agonist, morphine, and a KOR agonist (such as TRK820, a clinically approved drug in Japan for uremic pruritus) may prove useful for cancer therapy through the suppression of tumor angiogenesis by dual inhibition of VEGF ligands and receptors, extending the therapeutic benefits beyond pain relief.

Images: KOR was highly expressed in Flk1⁺ vascular progenitors. (A) RT-PCR showing mRNA expression of MOR, DOR, and KOR in ES cells, Flk1⁺ cells, cells after 1 or 3 days of Flk1⁺ cell culture (Flk-d1 or Flk-d3), CD31-positive cells (ECs) and CD31-negative cells (MCs) at Flk-d3. (B) Fluorescent staining for MOR, DOR, and KOR at Flk-d1. Nuclei are stained with DAPI (blue). Left, MOR; middle, DOR; right, KOR. Scale bars, 100 μm. (C) Double fluorescent staining for MOR, DOR, and KOR with CD31 (red) at Flk-d3. Nuclei are stained with DAPI (blue). Top, opioid (green) receptors (green); middle, CD31 (red); bottom, merged. Scale bars, 100 μm.

More on DOR

I am always delighted when we recieve positive feedback on one of our new reagents. It is even better when a researcher graciously shares images. I would like to thank Dr. Prof. Dr. Rapheal Sell of Freie Universität Berlin for sharing these excellent Immunofluorescence images:

Images: IF detection of delta-opioid receptors in tissue engineered human oral mucosa models using Delta Opioid Receptor 361-372. The tissues were frozen at -80°C, cut into 8 µm slices and fixed with formaldehyde solution. Blocking was performed with goat serum (dilutet 1:20 in PBS) for 30 minutes at RT. Primary antibody dilutions in PBS/BSA/Tween-20 were 1:500, 1:1000 and 1:1500, slides were incubated overnight at 4°C. Secondary (fluorescent) antibody was diluted 1:400, slides were incubated for 30 minutes at room temperature in the dark. Sections were mounted with antifading mounting medium DAPI (blue) and evaluated by fluorescent microscopy
