Aim: To investigate the expression of protein kinase CK2α (CK2α) in human thyroid disease and its relationship with thyroid cancer metastasis.
Materials And Methods: Using immunohistochemistry we measured the expression of CK2α in 76 benign and malignant human thyroid cancer tissues, including 10 pairs of papillary carcinoma tissues with or without lymph node cancerous metastasis and similarly 10 pairs of lymph nodes.
Results: The expression of CK2α was found to be higher in thyroid carcinoma cases (papillary carcinoma, follicular carcinoma, anaplastic carcinoma and medullary carcinoma) than in ones such as chronic lymphocytic thyroiditis, nodular goiter and adenoma. These findings were also confirmed by RT-PCR and Western blotting. More strikingly, elevated expression of CK2α in thyroid papillary carcinoma tissues was not only significantly associated with lymph node cancerous metastasis and clinical stage of thyroid cancers; but also correlated with epithelial-mesenchymal transition (EMT) and high tenascin C (TNC) expression. In addition, EMT and high TNC expression in thyroid carcinoma tissues was significantly associated with lymph node cancerous metastasis.
Conclusions: Elevated expression of nuclear CK2α is a poor prognosis indicator in lymph node cancerous metastasis of human thyroid cancers.

Dual Biological Role and Clinical Impact of De Novo Chromatin Activation in Chronic Lymphocytic Leukemia.

Previous studies have reported that chronic lymphocytic leukemia (CLL) shows a de novo chromatin activation pattern as compared to normal B cells. Here, we explored whether the level of chromatin activation is related to the clinical behavior of CLL. We identified that in some regulatory regions, increased de novo chromatin activation is linked to clinical progression whereas, in other regions, it is associated with an indolent course.

Protothecosis is a severe, emerging opportunistic infection caused by the saprophytic, achlorophyllous microalgae of the genus Prototheca. Though uncommon, human and animal cases are increasing worldwide, making awareness of this fungal-like pathogen important in both human and veterinary medicine. We report a fatal case of disseminated protothecosis caused by P.

Immunological interventions, like vaccinations, are enabled by the predictive control of humoral responses to novel antigens. While the development trajectories for many broadly neutralizing antibodies (bnAbs) have been measured, it is less established how human subtype-specific antibodies develop from their precursors. In this work, we evaluated the retrospective development trajectories for eight anti-SARS-CoV-2 Spike human antibodies (Abs).

Deuterium (H) MRI is an emerging tool for noninvasive imaging. We explore the integration of H MRI with deuterated multifunctional nanopolymers for deuterated particle imaging (DPI). To this end, amine-terminated G5-polyamidoamine (PAMAM) dendrimers were labeled with deuterated acetyl surface groups, leading to highly H-loaded bioparticles, making them ideal for imaging studies.

Aim: Lymphovascular invasion (LVI) is a well-known risk factor in colorectal cancer that is associated with a worse prognosis. The present study aimed to assess the characteristics of patients with LVI-positive colon cancer according to the status of nodal metastases and to study the association between LVI-nodal status and survival.
Method: This retrospective study assessed the association between LVI and lymph node metastases in colon cancer, using data from the National Cancer Database.
