ターゲット情報

  • 機能

    Receptor for thyrothropin. Plays a central role in controlling thyroid cell metabolism. The activity of this receptor is mediated by G proteins which activate adenylate cyclase. Also acts as a receptor for thyrostimulin (GPA2+GPB5).

  • 組織特異性

    Expressed in the thyroid.

  • 関連疾患

    Defects in TSHR are found in patients affected by hyperthyroidism with different etiologies. Somatic, constitutively activating TSHR mutations and/or constitutively activating G(s)alpha mutations have been identified in toxic thyroid nodules (TTNs) that are the predominant cause of hyperthyroidism in iodine deficient areas. These mutations lead to TSH independent activation of the cAMP cascade resulting in thyroid growth and hormone production. TSHR mutations are found in autonomously functioning thyroid nodules (AFTN), toxic multinodular goiter (TMNG) and hyperfunctioning thyroid adenomas (HTA). TMNG encompasses a spectrum of different clinical entities, ranging from a single hyperfunctioning nodule within an enlarged thyroid, to multiple hyperfunctioning areas scattered throughout the gland. HTA are discrete encapsulated neoplasms characterized by TSH-independent autonomous growth, hypersecretion of thyroid hormones, and TSH suppression. Defects in TSHR are also a cause of thyroid neoplasms (papillary and follicular cancers).
    Autoantibodies against TSHR are directly responsible for the pathogenesis and hyperthyroidism of Graves disease. Antibody interaction with TSHR results in an uncontrolled receptor stimulation.

    Familial gestational hyperthyroidism
    Hyperthyroidism, non-autoimmune

      ICC/IF image of ab6044 stained Hek293 cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal Goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab6044, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 Goat anti-Mouse IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

The cells were fixed with 80% methanol (5 min) and incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab6044, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG2b [PLPV219] (ab91633, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

      Please note that Abcam do not have any data for use of this antibody on non-fixed cells. We welcome any customer feedback.

    Question

    Please read below customer's answers:

    1. To explain both of the western blot images? Conditions used in each blot? Conditions for each lane?

    24.9.12 – The big membrane was divided into four membranes according to size of the desirable proteins. On both sides the same amount of protein was loaded (and it is the same origin – human thyroid cells). The two lower membranes are control for loading. The two sides are duplicates. The difference is the antibody used: left: ab-TSHR right: ab-MMP9. The conditions used for each lane were identical.

    The following is related to all four membranes in the image 24.9.12 and for the two membranes in the image 11.10.12:

    Lane 1: marker

    Lane 2: normal thyroid 15µg

    Lane 3: normal thyroid 40µg

    lane 4: thyroid tumor 15µg

    Lane 5: thyroid tumor 40µg

    Lane 6: thyroid metastasis 15µg

    Lane 7: thyroid metastasis 40µg

    11.10.12 The two membranes were stripped and I switched the membranes and reacted the left one with ab-MMP9 and the right with ab-TSHR in order to check if the problem was because of the specific membrane but again I got high background with no clue for the right bands. In this time I also diluted the ab two times more than recommended and diluted the ECL two times more as detailed in the complaint form.

    Each membrane was reacted with ECL according to the manufacturer's instructions.


    2. For image labeled 24/09/12, why is the top half of the blot overexposed when the bottom half isn't? Was this blot cut in half and treated differently? Exposure time was the same for all four membranes – about 1 second. The longer exposure times gave even darker images. The four membranes were treated in the same way and were exposed for the same time. The differences between the four membranes are only the antibodies.

    3. How long was this membrane exposed for? For 1-2 seconds.
