Alveolar rhabdomyosarcoma (RMS) has a much poorer outcome than embryonal RMS. In this study, we found that IGF-I affected the induction of myogenin and cell cycle progression in alveolar RMS cells, but not in embryonal RMS cells. IGF-I enhanced the induction of myogenin protein in alveolar RMS SJ-Rh30 and KP-RMS-MS cells as it did in myoblast C2C12 cells, but not in embryonal RMS RD or KP-RMS-K...

Rhabdomyosarcomas (RMS) bear a morphological resemblance to developing striated muscle. It has been reported that two histologically distinct subtypes of RMS, embryonal and alveolar, behave differently in many clinical aspects, such as age distribution, primary site, and prognosis. We have investigated the expression of various genes, which are preferentially expressed in normal muscle tissue o...

Five arotinoids have been compared with all-trans- and 13-cisretinoic acids for their ability to promote differentiation of cells from murine embryonal carcinoma line Nulli-SCC1. Ro-13-7410, which contains a terminal carboxylic acid residue, and Ro-14-9572, the sodium sulfinate derivative, are potent inducers of differentiation. The sodium sulfonate derivative, Ro-14-3899, is somewhat less acti...

Fusicoccin inhibits the germination of pea (Pisum sativum L. cv Progress 9) seeds by decreasing the growth of the embryonal axis and by stimulating the fresh weight increase of the cotyledons. The growth of isolated embryonal axes in the presence of sucrose and KCl is stimulated by fusicoccin. The effect of fusicoccin on the seeds is not counteracted by sucrose and KCl. Fusicoccin promotes pref...

purpose : to report the outcome of a case of primary conjunctival rhabdomyosarcoma treated by surgical excision combined with chemotherapy case report : a 4-year-old boy presented with a visible recurrence of conjunctival mass in the left eye. the orbital magnetic resonance imaging (mri) showed the lesion was confined to the conjunctiva without orbital infiltration. histology and immunophenotyp...

malignant mixed germ cell tumors,though rare overall, are the most common type of malignant ovarian neoplasms in young and adolescent girls. these tumors are rapidly growing and can metastasize. we report a case of 13-yr-old girl who presented at shkm gmc, nalhar, mewat, haryana, india in december 2013 with huge abdominal lump of a malignant mixed germ cell tumor comprising both immature terato...

Pluripotential human embryonal carcinoma (EC) cell linesundergo differentiation programs resembling those occurring in embryonal stem cells during development. Expression profiling was performed during the terminal differentiation of the EC cell line, NTera2/Clone D1 by all-trans-retinoic acid. Time-response analysis via clustering of >12,000 human transcripts revealed distinct stages in the tr...

A comparative study of beta enolase and myoglobin as markers of muscle differentiation in rhabdomyosarcoma was carried out, using an immunoperoxidase peroxidase antiperoxidase technique. Material from 26 cases of childhood rhabdomyosarcoma was studied and subdivided into embryonal and alveolar types. Positive cytoplasmic staining for beta enolase was seen in 85% of tumours studied (91% alveolar...
