摘要:
The invention relates to the discovery of a novel tumor suppressor gene which is associated with multiple endocrine neoplasia type 1. The gene has been designated MEN1 and the gene product is menin. The absence of this protein and associated mutations in the corresponding gene have been identified in individuals suffering from multiple endocrine neoplasia type 1. The identification of this marker for multiple endocrine neoplasia type 1 has diagnostic uses as well as for gene therapy.

This disclosure relates to CryoArrays, which permit the analysis of samples (such as protein, nucleic acid, virus, or cell samples) in arrays that are prepared at low temperatures. Because CryoArrays are constructed as a block of substantially columnar samples, the block can be sliced to provide a plurality of identical or substantially identical individual arrays. The individual arrays can be used for parallel analysis of the same array feature set, for instance with different probes or under different conditions. Also provided are methods of making CryoArrays, devices for making CryoArrays, and kits.
摘要:
A method of microdissection which involves: forming an image field of cells of the tissue sample utilizing a microscope, identifying at least one zone of cells of interest from the image field of cells which at least one zone of cells of interest includes different types of cells than adjacent zones of cells, and extracting the at least one zone of cells of interest from the tissue sample. The extraction is achieved by contacting the tissue sample with a transfer surface that can be selectively activated so that regions thereof adhere to the zone of cells of interest to be extracted. The transfer surface includes an activatable adhesive layer which provides chemical or electrostatic adherence to the selected regions of the tissue sample. After the transfer surface is activated the transfer surface and tissue sample are separated. During separation the zone of cells of interest remains adhered to the transfer surface and is thus separated from the tissue sample.

A method of inhibiting the invasion and metastasis of malignant solid tumors in mammals, said method comprising administering to said mammal an anti-proliferative, anti-invasive and anti-metastasis effective amount of a compound selected from the group of formulas consisting of: ##STR1## wherein: p is an integer of from 0 to 4; Ar.sup.1 is a moiety selected from the group consisting of --Ar.sup.2 --X--Ar.sup.3, phenyl, trioxaadamantyl, anthracenyl, anthraquinonyl, naphthyl, phenanthryl, and substituted versions thereof; Ar.sup.2 and Ar.sup.3 are each aromatic moieties independently selected from the group consisting of phenyl, naphthyl, and substituted versions thereof; X is a linking moiety selected from the group consisting of O, S, SO.sub.2 2, CO, CHCN, straight chain alkyl, alkoxy, and alkoxyalkyl; and Z is a nitrogen-containing heterocyclic moiety selected from the group consisting of imidazolyl, 1,2,3-triazolyl, 1,2,4-triazolyl and substituted versions thereof, said heterocyclic moieties being attached to the --(CH.sub.2).sub.p -- portion of the molecule at the N1 position of the heterocycle.
摘要:
Calcium homeostasis is an important regulator of MMP-2 transcription, activation and activity. Disclosed herein are compounds which inhibit the expression of matrix metalloproteinases in cells. Pharmaceutical application of these compounds to inhibit the expression of MMPs offers a new approach to cancer treatment as well as treatment for nerve healing, degenerative cartilagenous diseases, decubitus ulcers, arthritis, Alzheimer's disease, wound healing, proliferative retinopathy, proliferative renal diseases, corneal ulcers and fertility problems.
摘要:
Basement membrane collagen degrading enzymes are provided which are useful for the detection of malignant cells with metastatic activity. Means for detecting such cells are also provided.
摘要:
The specification and drawings disclose methods and apparatus for separating and/or isolating bacteria and tissue cells for testing or rapid automatic scanning. The invention uses an expansible membrane on which the tissue cell or bacteria sample is placed and thereafter expanded to cause the sample to be separated. Apparatus is disclosed for facilitating stretching of the membrane and automatically scanning it.
摘要:
Described herein are progenitor cancer cells and cell lines isolated from human breast ductal carcinoma in situ (DCIS) lesions and the uses of these cells or cell lines in drug design, drug screening, and monitoring in vivo therapy. The DCIS malignant precursor cells or cell lines are epithelial in origin, are positive for markers of autophagy, show at least one genetic difference from normal cells of said fragment, form 3-D tube-like structures or ball aggregates, or are inhibited in formation of 3-D structures and migration by treatment with chloroquine.
摘要:
The present invention provides reliable methods to identify subsets of subjects with a cancer of epithelial origin characterized by a high level of phosphorylated c-erbB2 which does not correlate with the over-expression of total c-erbB2 as measured by IHC or FISH, for selection and inclusion for c-erbB2-direct treatment and therapy. Furthermore, the present invention provides a reliable method to determine whether a subject with a cancer of epithelial origin who has been determined to be c-erbB2 positive by IHC and by FISH should be excluded from c-erbB2-direct treatment because of a non-significant level of phosphorylated c-erbB2 in epithelial tumor tissue.
摘要:
This invention relates, e.g., to a method for predicting the response of a subject having, or at risk of developing, breast cancer to Tamoxifen therapy. The method comprises measuring the amount of phosphorylation at residues S70 of Bcl-2, Y992 of EGFR, and/or Y527 of Src in a suitable sample from the subject, wherein a statistically significantly elevated level of phosphorylation at one or more of the three residues compared to a baseline value indicates that the subject is likely to be responsive to Tamoxifen therapy.
