Phosphosulindac (OXT-328) prevents and reverses chemotherapy induced peripheral neuropathy in mice.

Background: Chemotherapy-induced peripheral neuropathy (CIPN), a side effect of chemotherapy, is particularly difficult to treat. We explored whether phosphosulindac (PS), a modified NSAID, could treat CIPN.

Methods: CIPN was induced in male C57BL/6 J mice by paclitaxel, vincristine or oxaliplatin.

Effect of Dickkopf-1 (Dkk-1) and SP600125, a JNK Inhibitor, on Wnt Signaling in Canine Prostate Cancer Growth and Bone Metastases.

Human Dickkopf-1 (Dkk-1) upregulates a noncanonical Wnt/JNK pathway, resulting in osteoclast stimulation, cell proliferation, and epithelial-to-mesenchymal transition (EMT) of cancer cells. Ace-1-Dkk-1, a canine prostate cancer (PCa) cell line overexpressing Dkk-1, was used to investigate Wnt signaling pathways in PCa tumor growth. SP600125, a JNK inhibitor, was used to examine whether it would decrease tumor growth and bone tumor phenotype in canine PCa cells in vitro and in vivo.

Parathyroid hormone-related protein promotes bone loss in T-cell leukemia as well as in solid tumors.

Parathyroid hormone-related protein (PTHrP) and macrophage inflammatory protein-1α (MIP-1α) are important factors that increase bone resorption and hypercalcemia in adult T-cell leukemia (ATL). We investigated the role of PTHrP and MIP-1α in the development of local osteolytic lesions in T-cell leukemia through overexpression in Jurkat T-cells. Injections of Jurkat-PTHrP and Jurkat-MIP-1α into the tibia and the left ventricle of NSG mice were performed to evaluate tumor growth and metastasis .

Immunocharacterization of matrix metalloproteinase-2 and matrix metalloproteinase-9 in canine transmissible venereal tumors.

Matrix metalloproteases (MMPs) are endogenous proteases that are responsible for degradation of extracellular matrix (ECM) proteins and cell surface antigens. The breakdown of ECM participates in the local invasion and distant metastases of malignant tumors. Canine transmissible venereal tumor (CTVT) is a naturally occurring contagious round cell neoplasm of dogs that affects mainly the external genitalia of both sexes.

Clinical and epidemiological characteristics of thyroid hemiagenesis: ultrasound screening in patients with thyroid disease and normal population.

Thyroid hemiagenesis is a rare form of thyroid dysgenesis, in which one thyroid lobe fails to develop. The true prevalence of this rare abnormality is about 0.05-0.
