GRAIL1 Stabilizes Misfolded Mutant p53 through a Ubiquitin Ligase-Independent, Chaperone Regulatory Function.

Frequent (>70%) TP53 mutations often promote its protein stabilization, driving esophageal adenocarcinoma (EAC) development linked to poor survival and therapy resistance. We previously reported that during Barrett's esophagus progression to EAC, an isoform switch occurs in the E3 ubiquitin ligase RNF128 (aka GRAIL-gene related to anergy in lymphocytes), enriching isoform 1 (hereby GRAIL1) and stabilizing the mutant p53 protein. Consequently, GRAIL1 knockdown degrades mutant p53.

ISG15/GRAIL1/CD3 axis influences survival of patients with esophageal adenocarcinoma.

Immunosuppression is a common feature of esophageal adenocarcinoma (EAC) and has been linked to poor overall survival (OS). We hypothesized that upstream factors might negatively influence CD3 levels and T cell activity, thus promoting immunosuppression and worse survival. We used clinical data and patient samples of those who progressed from Barrett's to dysplasia to EAC, investigated gene (RNA-Seq) and protein (tissue microarray) expression, and performed cell biology studies to delineate a pathway impacting CD3 protein stability that might influence EAC outcome.

Isoform alterations in the ubiquitination machinery impacting gastrointestinal malignancies.

The advancement of RNAseq and isoform-specific expression platforms has led to the understanding that isoform changes can alter molecular signaling to promote tumorigenesis. An active area in cancer research is uncovering the roles of ubiquitination on spliceosome assembly contributing to transcript diversity and expression of alternative isoforms. However, the effects of isoform changes on functionality of ubiquitination machineries (E1, E2, E3, E4, and deubiquitinating (DUB) enzymes) influencing onco- and tumor suppressor protein stabilities is currently understudied.

A model-based clustering algorithm with covariates adjustment and its application to lung cancer stratification.

Methods: Peptide monomers specific for EGFR and ErbB2 were arranged in a heterodimer configuration and labeled with IRDye800.

CSE1L silencing impairs tumor progression via MET/STAT3/PD-L1 signaling in lung cancer.

CSE1L is involved in the cancer progression of several types of cancer. Its expression status, potential oncogenic role and underlying mechanism in lung cancer, however, are unclear. Here, we investigated CSE1L expression in primary lung adenocarcinoma based on multiple datasets and then investigated its oncologic role in lung cancer.

Perioperative airway complications in infants and children with Crouzon and Pfeiffer syndromes: A single-center experience.

Background: Crouzon and Pfeiffer syndromes are rare genetic disorders characterized by craniosynostosis, exorbitism, and maxillary hypoplasia. Patients with these syndromes frequently require general anesthesia for various diagnostic and surgical procedures and may present a challenge to anesthetists with regard to airway management.

Aims: The primary aim of this study was to determine the incidence, timing, and management of perioperative upper airway obstruction in infants and children with Crouzon and Pfeiffer syndromes.

UBCH5 Family Members Differentially Impact Stabilization of Mutant p53 via RNF128 Iso1 During Barrett's Progression to Esophageal Adenocarcinoma.

Background & Aims: TP53 mutations underlie Barrett's esophagus (BE) progression to dysplasia and cancer. During BE progression, the ubiquitin ligase (E3) RNF128/GRAIL switches expression from isoform 2 (Iso2) to Iso1, stabilizing mutant p53. However, the ubiquitin-conjugating enzyme (E2) that partners with Iso1 to stabilize mutant p53 is unknown.

Collagen modifying enzyme P4HA1 is overexpressed and plays a role in lung adenocarcinoma.

Lung cancer is the leading cause of cancer-related deaths globally and is histologically defined as either small cell lung cancer (SCLC) or non-small cell lung cancer (NSCLC), with the latter accounting for 80% of all lung cancers. The 5-year overall survival rate for lung cancer patients is low as it is often discovered at advanced stages when potential cure by surgical resection is no longer an option. To identify a biomarker and target for lung cancer, we performed analysis of multiple datasets of lung cancer gene expression data.

Immune determinants of Barrett's progression to esophageal adenocarcinoma.

Esophageal adenocarcinoma (EAC) develops from Barrett's esophagus (BE), a chronic inflammatory state that can progress through a series of transformative dysplastic states before tumor development. While molecular and genetic changes of EAC tumors have been studied, immune microenvironment changes during Barrett's progression to EAC remain poorly understood. In this study, we identify potential immunologic changes that can occur during BE-to-EAC progression.
