Norethindrone scatters silver-stained nucleolar organizer regions of Ishikawa cells.
We investigated the effects of sex steroids on silver-stained nucleolar organizer regions (Ag-NORs) and DNA/RNA kinetics in Ishikawa cells. Norethindrone and its isomer norethynodrel exclusively caused Ag-NORs to scatter in the nuclear matrix, from the nucleolus. No such effect occurred with the other sex steroids tested, including progestational, androgenic, and estrogenic compounds. Nuclear a...

متن کاملp53 and PCNA Expression in Keratocystic Odontogenic Tumors Compared with Selected Odontogenic Cysts
p53 and PCNA expression in keratocystic odontogenic tumors compared with selected odontogenic cysts Summary: The aim of this study was to evaluate p53 and PCNA expression in different odontogenic lesions regarding their different clinical behaviors. Slices prepared from 94 paraffin-embedded tissue blocks (25 radicular cysts (RC), 23 dentigerous cysts (DC), 23 keratocystic odontogenic tumors (KC...
متن کاملSilver stained Nucleolar organizer regions in nonneoplastic and neoplastic lesions of endometrium
Nucleolar organizer regions (NORs) are loops of DNA that transcribe to ribosomal RNA. They are associated with nonhistone nucleoproteins which can be stained with silver (AgNORs). The present retrospective study was done to study the efficacy of AgNOR technique in differentiating between non neoplastic and neoplastic lesions of endometrium and to assess the relationship between AgNOR counts and...
متن کاملCD56 Expression in Odontogenic Cysts and Tumors
Background and aims. Odontogenic cysts and tumors have a wide spectrum of clinical characteristics that lead to the different management strategies. Since definite diagnosis is difficult in some cases, it has been suggested that CD56 may be a candidate marker for definitive diagnosis of some odontogenic tumors. The present study was designed to examine CD56 expression in lesions with histopatho...
