METHODS AND REAGENTS FOR DETECTING CpG METHYLATION WITH A METHYL CpG BINDING PROTEIN (MBP)

The present invention provides a simple and sensitive technology for the detection of CpG methylation in DNA without chemical modification of sample DNA by bisulfite treatment or PCR amplification. Signal generation is based on an Abscription (Abortive Transcription) technology in which DNA signal generators called Abortive Promoter Cassettes (APCs) are bound to target mCpG sites via mCpG target specific probes based on methyl binding polypeptides or methyl binding domains thereof. RNA polymerase produces uniform, short RNA molecules from synthetic promoters in APCs as signals of the presence of methylated CpGs. Detection of CpG methylation and hypermethylation of DNA targets such as CpG islands provides a convenient means for detecting and monitoring cancer in a subject.

Development of a highly sensitive quantification system for assessing DNA degradation and quality in forensic samples

A process of quantifying the extent of degradation present in a human DNA sample is described. The process makes use of a real time PCR system to separately quantitate within a sample a first retrotransposon interspersed element and a relatively longer second retrotransposon interspersed element, where the longer element is expected to be disrupted at a faster pace than is the shorter element as the sample degrades. In one embodiment, the process makes use of the appearance of the relatively young (on an evolutionary scale) Alu Yb-lineage subfamily sequences appearing in every human genome and their virtual absence in non-human samples. In a preferred embodiment, the process quantifies longer 290 bp sequences of “SVA” elements and shorter 80 bp sequences of Alu Yb8-lineage. Newly designed primers and TaqMan probes that are useful in the process are presented. A related process additionally quantifies male specific human DNA.

Method of training a dog to chew acceptable objects through scent marking and chemical composition thereof

A positive-reinforced method of training a dog to chew or mouth only appropriate household items and chew toys. The method includes scent-training the dog (or puppy) to recognize a particular distinctive scent not normally found in nature as applied to an acceptable chewing object. The dog is introduced to the distinctive scent and encouraged to chew the marked acceptable chewing object. Each time the dog recognizes the scent, the dog is encouraged to chew the scented chewing object or some other acceptable chewing object marked with the distinctive scent and rewarded. The dog is tested with at least one unmarked object. The dog is trained once the dog can discriminate between the scent-marked object or objects and the unmarked object or objects. From there, the scent may be applied to other household items that are acceptable chewing / mouthing items (e.g., other chew toys). By absence of the scent, the dog recognizes that it cannot chew on unacceptable items (e.g., furniture, shoes). The scent may be applied to acceptable chewing / mouthing items in liquid form or as a gel. The scent is aromatic to dogs but not to people. The invention also includes the chemical composition of the scent used in the method training.
