Project description:The objectives of this investigation were to examine changes in the host transcriptional profiles during a Porphyromonas gingivalis infection using a murine calvarial model of inflammation and bone resorption. P. gingivalis strain 381 was injected into the subcutaneous soft tissue over the calvaria of BALB/c mice for 3 days, after which the soft tissues and calvarial bones were excised. RNA was isolated from infected soft tissues and calvarial bones and analyzed for transcript profiles using Murine GeneChip® MG-MOE430A Affymetrix arrays to provide a molecular profile of the events that occur following infection of these tissues. We used mouse microarrays to detail the molecular profile of the events that occur following infection of calvarial and bone tissues and identified distinct classes of up- and down-regulated genes during this process.

Project description:Bispecific T-cell engager (BiTE)-based cancer therapies that activate the cytotoxic T cells of a patient’s own immune system have gained momentum with the recent FDA approval of Blinatumomab for treating B cell malignancies. However, this approach has had limited success in targeting solid tumors. We have reported the development of BiTE-sialidase fusion proteins that enhance tumor cell susceptibility to BiTE-mediated cytolysis by T cells via targeted desialylation at the BiTE-induced T cell-tumor cell interface. Targeted desialylation results in better immunological synapse formation, T-cell activation and effector function. As a result, BiTE-sialidase fusion proteins show remarkably increased efficacy in inducing T-cell-dependent tumor cell cytolysis in response to target antigens compared to the parent BiTE molecules alone. This enhanced function is seen both in vitro and in in vivo xenograft and syngeneic solid tumor mouse models. Our findings highlight BiTE-sialidase fusion proteins as promising candidates for the development of next-generation bispecific T-cell engaging molecules for cancer immunotherapy. This transcriptomic dataset documents the effect of BiTE-sialidase vs uncojugated BiTE on T cells including the upregulation of effector associated genes.

We used mouse microarrays to detail the molecular profile of the events that occur following infection of calvarial and bone tissues and identified distinct classes of up- and down-regulated genes during this process. P. gingivalis was injected at 1.5 x 10E9 (N = 10) into the soft tissues overlying the calvaria of the mice for 3 days. A control group (N = 9) was injected with vehicle once daily for 3 days. Mice were euthanized 8 h after the last injection. The calvarial bones and overlying soft tissues from 5 mice in each group were excised, snap frozen in liquid nitrogen, and stored at –80°C until RNA isolation. Total RNA was isolated from the frozen calvarial tissue and calvarial bone from each mouse (P. gingivalis infected and control animals) with Trizol reagent (Invitrogen, CA). Equal amounts of RNA from samples were labeled and hybridized on a mouse GeneChip following the protocol described in the GeneChip Expression Analysis Technical manual (Affymetrix, Santa Clara, CA). After hybridization, the GeneChip arrays were stained and scanned in an Affymetrix GCS 3000 7G Scanner.
