A case of rhabdoid meningioma originating from the optic nerve.

Neuropathology

January 2025

Department of Pathology, Shenzhen Second People's Hospital, Shenzhen University 1st Affiliated Hospital, Shenzhen, China.

We report a rare case of rhabdoid meningioma (RM) originating from the optic nerve in a 57-year-old female. The tumor exhibited rhabdoid or epithelioid histology and harbored BAP1 inactivation mutations. Optic nerve meningioma typically originates from the outer meningeal cells of the optic nerve within the optic canal and is usually benign, with most cases classified as meningothelial or transitional meningiomas.

New onset of protein-losing enteropathy in a patient with Fontan circulation after COVID-19 vaccination: dread the cure or the disease?

Cardiol Young

January 2025

Adult Congenital Heart Centre and National Centre for Pulmonary Hypertension, Royal Brompton and Harefield Hospitals, Guy's and St Thomas's NHS Foundation Trust, Imperial College, London, UK.

We present the case of a 31-year-old female with Fontan circulation who developed signs of protein-losing enteropathy 10 days after second COVID-19 vaccination. After standard investigations for identification of potential triggers for protein-losing enteropathy, we concluded that coronavirus disease 2019 (COVID-19) booster vaccination could have been the most probable underlying trigger. Prompt investigation of new symptoms post-vaccination in high-risk patients is necessary.

Enhanced membrane protein production in HEK293T cells via gene knockout: A CRISPR-Cas9 mediated approach.

Biomol Biomed

January 2025

Catholic Central Laboratory of Surgery, College of Medicine, The Catholic University of Korea, Seoul, Republic of Korea; Translational Research Team, Surginex Co., Republic of Korea; Department of Surgery, Seoul St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Republic of Korea.

HEK293T cells are extensively utilized for therapeutic protein production due to their human origin, which enables accurate post-translational modifications. This study aimed to enhance membrane protein production in HEK293T cells by knocking out the ATF4 gene using CRISPR-Cas9 technology. The ATF4 gene was edited by infecting HEK293T cells with a lentivirus carrying optimized single-guide RNA (ATF4-KO-3) and Cas9 genes.

The epithelial-mesenchymal transition (EMT) assists in the acquisition of invasiveness, relapse, and resistance in non-small cell lung cancer (NSCLC) and can be caused by the signaling of transforming growth factor-β1 (TGF-β1) through Smad-mediated or Smad-independent pathways. (-)-Epigallocatechin-3-gallate (EGCG), a multifunctional cancer-preventing bioconstituent found in tea polyphenols, has been shown to repress TGF-β1-triggered EMT in the human NSCLC A549 cell line by inhibiting the activation of Smad2 and Erk1/2 or reducing the acetylation of Smad2 and Smad3. However, its impact on the Smad-independent pathway remains unclear.

A preliminary ex vivo diffusion tensor imaging study of distinct aortic morphologies.

J Anat

January 2025

Trinity Centre for Biomedical Engineering, Trinity Biomedical Sciences Institute, Trinity College Dublin, Dublin, Ireland.

Changes in the microstructure of the aortic wall precede the progression of various aortic pathologies, including aneurysms and dissection. Current clinical decisions with regards to surgical planning and/or radiological intervention are guided by geometric features, such as aortic diameter, since clinical imaging lacks tissue microstructural information. The aim of this proof-of-concept work is to investigate a non-invasive imaging method, diffusion tensor imaging (DTI), in ex vivo aortic tissue to gain insights into the microstructure.
