摘要:
The present invention is concerned with two novel monoclonal antibodies which define carbohydrate antigens associated with human non-small cell lung carcinomas ("NSCLC") and certain other human carcinomas. The antibodies bind to normal human cells to a much lesser degree than to tumor cells. The antibodies find use in diagnostic methods such as the detection of malignant cells associated with NSCLC and in therapeutic methods. The invention also comprises a method for determining the presence of a malignant condition in the lung of a subject. The method involves examining tissue from the subject for the presence of antigens which are Le.sup.x or Le.sup.y antigen or which have the characteristics of Le.sup.y and Le.sup.x.

Methods, apparatus and software for classifying queries. In an aspect, for each of a plurality of queries, determines a first value based on a first number of occurrences for which the query was received for unfiltered search operations, and a determines a second value based on a second number of occurrences for which the query was received for filtered search operations. The method determines a first content type value based on the first value and the second value, and for each of the plurality of queries having a first content type value that meets a first threshold, classifies the query as a first content type seeking query, the classification being indicative of likely user interest in content of the first type.

Methods and compositions are provided that are useful for detecting and reporting a plurality of different target polynucleotide sequences in a sample, such as polynucleotides corresponding to a plurality of different genes expressed by a cell or cells. In particular, the invention provides methods for screening a plurality of candidate polynucleotide probes to evaluate both the sensitivity and the specificity with which each candidate probe hybridizes to a target polynucleoide sequence. Candidate polynucleotide probes can then be ranked according to both their sensitivity and specificity, and probes that have optimal sensitivity and specificity for a target polynucleotide sequence can be selected. In one embodiment, polynucleotide probes can be selected according to the methods described herein to prepare “screening chips” wherein a large number of target polynucleotide sequences are detected using a single microarray have a few (e.g., 1-5) probes for each target polynucleotide sequence. In a particularly preferred embodiment, the invention provides a screening chip that can detect genetic transcripts from the entire genome of an organism. In an alternative embodiment, polynucleotide probes can be selected according to the methods described herein to prepare “signature chips” to more accurately detect certain selected “signature genes” using several polynucleotide probes (e:g., 10-20) for each signature gene. The invention additionally provides microarrays containing polynucleotide probes for a large number of genes expressed by a cell or organism. Further, methods for detecting a plurality of polynucleotide molecules, including a large number of genes expressed by a cell or organism, are also provided.

The present invention is concerned with novel monoclonal antibodies which define a glycolipid antigen associated with human non-small cell lung carcinomas ("NSCLC") and certain other human carcinomas. The antibodies bind to normal human cells to a much lesser degree than to tumor cells. The antibodies find use in diagnostic methods such as the detection of malignant cells associated with NSCLC and in therapeutic methods. Also disclosed in a novel glycolipid antigen. The invention also comprises a method for determining the presence of a malignant condition in lung tissue and other human tissue. The method involves examining the human tissue for the presence of a glycolipid antigen having the terminal carbohydrate sequence: GalNAc.beta.l.fwdarw.4Gal.beta.l.fwdarw.3GalNAc.beta.l.fwdarw.4Gal.beta.l.fwdarw.R.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for previewing search results. In one aspect, a method includes receiving a query from a client device. One or more image search results are provided to the client device, each of the one or more image search results identifying a corresponding image resource and each of the one or more image search results including an image representation of the corresponding image resource. One or more related queries are provided to the client device, the one or more related queries having been determined to be related to the query, wherein each of the one or more related queries includes a preview image to be displayed at the client device, the preview image representing an image search result responsive to the related query.

The present invention relates to methods and compositions for treating cancers by reducing the expression or activity of one or more of the genes encoding protein kinases ATR, MAST2, MAP3K6, TBK1, ADRBK2, CDKL2, LATS2, STK32B, STK11, DDR13 PSKH2, and NEK8, and/or the encoded kinases. The invention also relates to methods and compositions for determining the responsiveness of a cancer patient to anti-cancer drugs based on the status of one or more of such kinases. The invention further relates to methods and compositions for screening compounds that can be used to modulate the expression/activity of these kinases.

The invention identifies the CTLA4 receptor as a ligand for the B7 antigen. The complete amino acid sequence encoding human CTLA4 receptor gene is provided. Methods are provided for expressing CTLA4 as an immunoglobulin fusion protein, for preparing hybrid CTLA4 fusion proteins, and for using the soluble fusion proteins, fragments and derivatives thereof, including monoclonal antibodies reactive with B7 and CTLA4, to regulate T cell interactions and immune responses mediated by such interactions.
