Spatiotemporal Characterization of Cyclooxygenase Pathway Enzymes During Vertebrate Embryonic Development
Leathers et al., Developmental Biology. 2025.
https://pubmed.ncbi.nlm.nih.gov/39581452/
The cyclooxygenase (COX) pathway plays a fundamental role in embryonic development. Disruptions of the COX pathway during pregnancy cause developmental anomalies, including craniofacial clefts, impaired gut innervation, and neural tube defects in the embryo. Researchers used Gallus gallus embryos to study the expression of COX pathway enzymes during neurulation. COX-1 protein expression was upregulated in cells undergoing mitosis, whereas COX-2 protein expression was ubiquitous. This study provides spatiotemporal expression data of COX pathway enzymes at key embryonic development stages in G. gallus and guides future studies focused on defining the role of these enzymes during embryonic development.

Pembrolizumab and Cabozantinib in Recurrent Metastatic Head and Neck Squamous Cell Carcinoma: A Phase 2 Trial
Saba et al., Nature Medicine. 2023.

A multicenter clinical trial was conducted in 33 evaluable (36 enrolled) patients with recurrent metastatic head and neck squamous cell carcinoma (RMHNSCC) on a regimen combining cabozantinib, a tyrosine kinase inhibitor, with the standard of care of anti–programmed cell death protein 1 agent pembrolizumab. Results showed that 17 patients (52%) exhibited partial response and 13 (39%) exhibited stable disease, with an overall clinical benefit rate of 91%. Median progression-free survival (PFS) was 14.6 months, and the 1-year PFS was 54%. The pembrolizumab and cabozantinib regimen was well tolerated in patients with RMHNSCC. The promising clinical benefit warrants further investigation. Supported by ORIP (S10OD021644), NCI, and NIDCR.
Trim-Away Mediated Knock Down Uncovers a New Function for Lbh During Gastrulation of Xenopus laevis
Weir et al., Developmental Biology. 2021.
https://pubmed.ncbi.nlm.nih.gov/33159936/
The protein Lbh was identified as necessary for cranial neural crest cell migration in Xenopus. To investigate its role in embryonic events, the authors employed the technique "Trim-Away" to degrade this maternally deposited protein. Trim-Away utilizes the E3 ubiquitin ligase trim21 to degrade proteins targeted with an antibody. Early knockdown of Lbh in Xenopus results in defects in gastrulation that present with a decrease in fibronectin matrix assembly, an increase in mesodermal cell migration and decrease in endodermal cell cohesion. The technique is also effective on a second abundant maternal Protein Kinase C And Casein Kinase Substrate In Neurons 2. Supported by ORIP (R24OD021485) and NIDCR.
