250 results about "Response element" patented technology

Response elements are short sequences of DNA within a gene promoter region that are able to bind specific transcription factors and regulate transcription of genes. Under conditions of stress, a transcription activator protein binds to the response element and stimulates transcription. If the same response element sequence is located in the control regions of different genes, then these genes will be activated by the same stimuli, thus producing a coordinated response.

Disclosed are bioluminescent bioreporter integrated circuit devices that detect selected analytes in fluids when implanted in the body of an animal. The device comprises a bioreporter that has been genetically engineered to contain a nucleic acid segment that comprises a cis-activating response element that is responsive to the selected substance operably linked to a gene encoding a bioluminescent reporter polypeptide. In preferred embodiments, the target analyte is glucose, glucagons, or insulin. Exposure of the bioreporter to the target substance causes the response element to up-regulate the nucleic acid sequence encoding the reporter polypeptide to produce a luminescent response that is detected and quantitated. In illustrative embodiments, the bioreporter device is encapsulated on an integrated circuit that is capable of detecting the emitted light, processing the resultant signal, and then remotely reporting the results. Also disclosed are controlled drug delivery systems capable of being directly or indirectly controlled by the detection device that provide drugs such as insulin to the animal in reponse to the amount of target analyte present in the body fluids.

Shoe with sensors, controller and active-response elements and method for use thereof

Active-response golf shoes are disclosed. The golf shoes include at least one sensor, a controller, and at least one active-response element. The sensor and controller operate to rapidly determine if a golfer is walking or swinging a golf club. Once this determination is made the controller and active-response element rapidly change the shoe's characteristics. If the controller determines that the golfer is walking, the shoe provides a soft and flexible walking platform. If the controller determines that the golfer is swinging, the shoe morphs or changes automatically to provide a stable hitting platform. The controller senses various predetermined conditions such as pressure under the ball of the user's foot to determine whether the golfer is walking or swinging. The active-response elements may be a sole adjuster, a lace adjuster, and / or an upper adjuster. Methods of determining the golfer's type of movement are also disclosed.

System and method for generating a single use password based on a challenge/response protocol

A system and method which generates a single use password based on a challenge / response protocol. A box manager module executing within a security appliance identifies a public key (P) and salt value (S) associated with an administrator's smart card and generates a random nonce (N). The box manager transmits a challenge comprising the following elements: <SHA1(N), BM_ID, P[N, BM_ID], S>. Upon receiving the challenge, the administration card decrypts P[N, BM_ID] using the private key contained within the card and computes SHA1(N). The administration card then compares its computed values with the received values from the box manager. If the values match, then to the administration card returns a response comprising the following elements: HMAC_N[user, SHA1 (password, S)], where HMAC_N represents the SHA1 keyed hash message authentication check of the response elements using the nonce N as the key.

Live Attenuated Influenza Virus Vaccines Comprising Microrna Response Elements

The invention is directed to novel live attenuated influenza virus (LAIV) vaccines comprising one or more microRNA (miRNA) Response Element(s) (MRE) within an influenza virus genome. The MREs useful for the present invention can be derived from any miRNA which is highly expressed in influenza-targeted cells of an animal in need of vaccination but are not expressed or are expressed at very low levels in species (e.g., embryonated chicken eggs) or cell lines used for a large-scale vaccine production. This allows efficient vaccine production but renders the vaccine virus susceptible to attenuation in the influenza-targeted cells of vaccinated animals expressing a cognate miRNA.

Compositions and methods for the modification of physiological responses in plants

A gene expression system for controllable expression of ethylene response in a plant cell includes an activation cassette comprising a DNA-binding domain that recognizes a response element; an ecdysone receptor ligand binding domain; and an activation domain; and a target cassette comprising an inducible promoter, which comprises, in operative association, the response element and a minimal promoter responsive to the activation domain. The inducible promoter controls the expression of a nucleic acid sequence that encodes a selected protein that modifies sensitivity to ethylene in the plant. Interaction among the components of the activation cassette and target cassette, when in a plant cell, in the presence of an inducing composition, modulates expression of the selected protein and selectively modulates ethylene sensitivity in the plant cell. This modulation in the expression of the protein is controlled by the timing, the concentration and the duration of the application of the inducing composition. Transgenic plant cells, tissues, organs and entire plants are provided, which in the presence of the inducing composition control ethylene sensitivity. Ethylene sensitivity and / or ethylene production in such transgenic plants and tissues may be controlled for purposes of manipulating ripening, flower senescence and other ethylene sensitive functions of the plant.
