Method for the Early Detection of Renal Disease Using Proteomics

A method for the detection of an early biomarker for assessing a change in renal status in a mammalian subject following a renal event. The method typically includes the steps of (a) providing a body fluid sample obtained from a mammalian subject; (b) analyzing the molecular weight of the proteins in the sample using proteome analysis; and (c) identifying the presence of a protein in the sample selected from the group consisting of a 6.4 kDa protein, a 28.5 kDa protein, a 33 kDa protein, a 44 kDa protein, a 67 kDa protein, and combinations thereof. The presence of one of these proteins can serve as an early biomarker for assessing a change in renal status. The levels of these proteins can be compared to predetermined levels, and thus provide a determination of the subject's renal status. The invention also includes a method of assessing the administration of aprotinin during cardio-pulmonary bypass surgery and provides for methods where the level of the 6.4 kDa biomarker in the subject's urine directs a caregiver's therapeutic decision regarding the intra-operative administration of aprotinin.

Anther-specific genes, their promoters, and uses of the same

The present invention provides novel anther-specific genes, their promoters, and uses of the same. Rice seedlings were treated with gibberellin, and then genes and proteins with up-regulated expression were screened using DNA microarray analysis and proteome analysis. As a result, eight types of β-tubulins were identified. Among them, OsTUB8 was expressed specifically in the anther. Thus OsTUB8 was suggested to be involved in male sterility in rice, and it was thought that regulating OsTUB8 expression in plants could alter plant fertility. In addition, OsTUB8 promoters were thought to comprise anther-specific activity. Thus, the present invention can be said to be highly valuable when used as a tool for anther-specific gene expression.

Functional enviromics method for cell culture media engineering

This invention refers to a new method for optimizing the composition of cell culture media. This new method comprises two main stages. In the first stage, a functional enviromics map is built through the joint screening of cell functions and medium factors by the execution of a specific cell culture protocol and exometabolome assays protocol. The functional enviromics map consists of a data array of intensity values of elementary cellular functions against medium factors. In the second stage, optimized cell culture medium formulations are developed that either enhance or repress target elementary cellular functions from columns of the functional enviromics map. The main advantage of this method lies in enabling metabolic engineering through the culture media composition manipulation, wherein an arbitrarily high number of cell functions are optimized through manipulation of medium factors, as opposed to previous methods, which are eminently empirical, are not cell function oriented, and require a much higher number of experiments. Furthermore, this new method is based on cost-effective exometabolome assays and does not require costly intracellular genomic or proteomic assays.

The mixed sample is then separated using an LC separation system and the separated sample is then passed through a mass spectrometer to acquire data of the peptide characterization data from the separated sample. Various modifications and alterations to the MS acquisition process that enhance the effectiveness of the process are also described.
