SpatialESD: Spatial Ensemble Domain Detection in Spatial Transcriptomics

Advanced Science, EarlyView.
ABSTRACT Spatial transcriptomics (ST) measures gene expression while preserving spatial context within tissues. One of the key tasks in ST analysis is spatial domain detection, which remains challenging due to the complex structure of ST data and the varying performance of individual clustering methods. To address this, we propose SpatialESD, a Spatial

RT-PCR Analysis of TOPBP1 Gene Expression in Hereditary Breast Cancer [PDF]

, 2010
Hereditary predisposition to breast cancer determined in large part by loss of function mutations in one of two genes BRCA1 and BRCA2. Besides BRCA1 and BRCA2 other genes are also likely to be involved in hereditary predisposition to breast cancer ...

BRCA1 protein expression and subcellular localization in primary breast cancer: Automated digital microscopy analysis of tissue microarrays.

PLoS ONE, 2017
PurposeMutations in BRCA1 are associated with familial as well as sporadic aggressive subtypes of breast cancer, but less is known about whether BRCA1 expression or subcellular localization contributes to progression in population-based settings ...

Species Dependent Toxicity Comparison Outcome

Advanced Science, EarlyView.
By quantitatively assessing and comparing toxicity responses across different animal species and material compositions, our data reveal that toxicity rankings among different materials may be reversed across species. ABSTRACT Toxicity comparison plays a crucial role in material selection across diverse application fields.

BRCA1 intronic Alu elements drive gene rearrangements and PARP inhibitor resistance

Nature Communications, 2019
BRCA1 mutations located within the BRCT domain result in proteasomal degradation and sensitivity to PARP inhibitors (PARPi). Here, the authors report genetic rearrangements in the BRCA1 gene that generate a BRCT-less BRCA1 protein isoform, which avoids ...

Selenium‐Based Nanoplatforms: An Emerging Theranostic Paradigm for Gynecological Cancers

Advanced Science, EarlyView.
This reivew summarizes Selenium as a multifunctional anticancer regulator in gynecological cancers. It reduces tumor risk, enhances therapeutic efficacy, and reduces treatment toxicity. Selenium also overcomes chemoraditherapy resistance, improving overall treatment outcomes. ABSTRACT Gynecological cancers present significant therapeutic challenges due

The BRCA1 Breast Cancer Suppressor: Regulation of Transport, Dynamics, and Function at Multiple Subcellular Locations

Scientifica, 2012
Inherited mutations in the BRCA1 gene predispose to a higher risk of breast/ovarian cancer. The BRCA1 tumor suppressor is a 1863 amino acid protein with multiple protein interaction domains that facilitate its roles in regulating DNA repair and ...

A complete protein truncation test for BRCA1 and BRCA2 [PDF]

European Journal of Human Genetics, 1998
The protein truncation test (PTT) is currently the fastest method in general use for detecting previously unidentified mutations in tumor suppressor genes. Greater than three kilobases of coding sequence can be screened by one PCR reaction, one coupled in vitro transcription/translation reaction, and one lane on an SDS-PAGE gel.

Discovery of a Potent Fluorescence Polarization Probe for Identifying USP1 Allosteric Inhibitors

Advanced Science, EarlyView.
This study presents the first ubiquitin‐specific protease 1 (USP1) allosteric fluoroprobe and fluorescence polarization assay, enabling the differentiation of allosteric and catalytic site inhibitors. Further, a novel class of tetrahydroisoquinoline‐based USP1 inhibitors is designed, with compound 14a (USP1 IC50 = 29.9 nM) showing strong selectivity ...
