Antibody-Based Targeting of Cell Surface GRP94 Specifically Inhibits Cetuximab-Resistant Colorectal Cancer Growth.

Colorectal cancer (CRC) is one of the leading causes of cancer death worldwide. Cetuximab, a human/mouse chimeric monoclonal antibody, is effective in a limited number of CRC patients because of cetuximab resistance. This study aimed to identify novel therapeutic targets in cetuximab-resistant CRC in order to improve clinical outcomes.

Development of a sandwich enzyme-linked immunosorbent assay for the detection of CD44v3 using exon v3- and v6-specific monoclonal antibody pairs.

It has been suggested that soluble CD44 levels in cancer patient sera may be closely associated with tumor progression and metastasis. However, to date, there has been limited methodology for detecting the soluble CD44 variant 3 isoform (CD44v3). Herein, using phage display technology, we isolated monoclonal antibodies specific to exon v3 or v6 of CD44 (CD44-exonv3 or CD44-exonv6) from a human synthetic antibody library.

Data set for transcriptional response to depletion of the Shoc2 scaffolding protein.

The Suppressor of Clear, Caenorhabditis elegans Homolog (SHOC2) is a scaffold protein that positively modulates activity of the RAS/ERK1/2 MAP kinase signaling cascade. We set out to understand the ERK1/2 pathway transcriptional response transduced through the SHOC2 scaffolding module. This data article describes raw gene expression within triplicates of kidney fibroblast-like Cos1 cell line expressing non-targeting shRNA (Cos-NT) and triplicates of Cos1 cells depleted of SHOC2 using shRNA (Cos-LV1) upon activation of ERK1/2 pathway by the Epidermal Growth Factor Receptor (EGFR).

Shoc2-tranduced ERK1/2 motility signals--Novel insights from functional genomics.

The extracellular signal-regulated kinase 1 and 2 (ERK1/2) pathway plays a central role in defining various cellular fates. Scaffold proteins modulating ERK1/2 activity control growth factor signals transduced by the pathway. Here, we analyzed signals transduced by Shoc2, a critical positive modulator of ERK1/2 activity.

Estrogen Receptor Alpha (ESR1)-Dependent Regulation of the Mouse Oviductal Transcriptome.

Estrogen receptor-α (ESR1) is an important transcriptional regulator in the mammalian oviduct, however ESR1-dependent regulation of the transcriptome of this organ is not well defined, especially at the genomic level. The objective of this study was therefore to investigate estradiol- and ESR1-dependent regulation of the transcriptome of the oviduct using transgenic mice, both with (ESR1KO) and without (wild-type, WT) a global deletion of ESR1. Oviducts were collected from ESR1KO and WT littermates at 23 days of age, or ESR1KO and WT mice were treated with 5 IU PMSG to stimulate follicular development and the production of ovarian estradiol, and the oviducts collected 48 h later.
