Pancreatic stellate cells (PSCs) differentiate into cancer-associated fibroblasts (CAFs) that produce desmoplastic stroma, thereby modulating disease progression and therapeutic response in pancreatic ductal adenocarcinoma (PDA). However, it is unknown whether CAFs uniformly carry out these tasks or if subtypes of CAFs with distinct phenotypes in PDA exist. We identified a CAF subpopulation wit...
BACKGROUND Desmoplastic small round cell tumor (DSRCT) is an extremely rare sarcomatous tumor, which is most commonly seen in men. Clinicians managing a patient with a rapidly enlarging mass in pregnancy should be aware of the risk for malignancy. CASE A 31-year-old woman was found to have a newly enlarged ovarian mass in the second trimester. She subsequently underwent a laparotomy for remov...
Desmoplastic ameloblastoma (DA) is one of the 6 histopathological subtypes of ameloblastoma. Hybrid lesions in which histopathologically conventional ameloblastoma coexists with areas of DA are rare. A 40-year-old male was referred to our hospital complaining of a swelling in the right premolar region of the mandible. A panoramic radiograph showed an area of radiolucency with a well-defined cor...
The dense collagen network in tumors significantly reduces the penetration and efficacy of nanotherapeutics. We tested whether losartan--a clinically approved angiotensin II receptor antagonist with noted antifibrotic activity--can enhance the penetration and efficacy of nanomedicine. We found that losartan inhibited collagen I production by carcinoma-associated fibroblasts isolated from breast...
