The first somatic single cells of carrot hypocotyl explants having the competence to form embryos in the presence of 2,4-dichlorophenoxyacetic acid (2,4-D) were identified using semi-automatic cell tracking. These competent cells are present as a small subpopulation of enlarged and vacuolated cells derived from cytoplasm-rich and rapidly proliferating(More)
In a search for the plant equivalent of calsequestrin or calreticulin, the high capacity, low affinity Ca2+ binding proteins of muscle and non-muscle cells thought to play important roles in Ca2+ storage, we purified two Ca(2+)-binding proteins from spinach leaves. The proteins had apparent molecular weights of 55 and 53 kDa. On Western blot, they did not(More)
Potassium is an essential nutrient which plays an important role in many aspects of plant growth and development. Plants have developed a number of highly specific mechanisms to take up potassium from the soil; these include the expression of K(+) transporters and potassium channels in root cells. Despite the fact that root epidermal and hair cells are in(More)
Actually, in literature there are not valid tools able to predict the chemotherapy response during first-line ovarian cancer treatment. CA125 and human epididymis protein 4 (HE4) levels of consecutive single-institution patients with epithelial ovarian cancer (EOC) were measured during first-line chemotherapy and until 6 months follow-up. First, patients(More)
Carcinosarcomas of the female genital tract are rare tumors with an aggressive clinical behavior. Trastuzumab, a humanized monoclonal antibody, acts by binding to HER2/neu extracellular domain and exhibits therapeutic efficacy in HER2/neu-overexpressing cancers. Two uterine carcinosarcomas (UMMT-ARK-1, UMMT-ARK-2) and 2 ovarian carcinosarcomas (OMMT-ARK-1,(More)
The aim of this study is to evaluate the efficacy and safety of the combination of carboplatin and paclitaxel as neoadjuvant chemotherapy (NACT) in patients affected by locally advanced cervical cancer. Between June 2007 and May 2012, all patients with a diagnosis of locally advanced cervical cancer (IB2–IIB) were eligible for this protocol. All patients(More)
This study aims to investigate the correlation between preoperative human epididymis protein 4 (HE4) levels, endometrial cancer (EC) staging, and ideal cutoff for stage prediction. All EC patients, treated within January 2009 and February 2014 at the Division of Gynaecologic Oncology of the University Campus Bio-Medico of Rome, were considered for the(More)
Uterine serous carcinoma (USC) is a biologically aggressive subtype of endometrial cancer. We analyzed the mutational landscape of USC by whole-exome sequencing of 57 cancers, most of which were matched to normal DNA from the same patients. The distribution of the number of protein-altering somatic mutations revealed that 52 USC tumors had fewer than 100(More)
OBJECTIVE To compare the in vitro sensitivity/resistance to patupilone versus paclitaxel in uterine and ovarian carcinosarcomas (CS). METHODS Five primary carcinosarcoma cell lines, two from uterine and three of ovarian origin, were evaluated for growth rate and tested for their in vitro sensitivity/resistance to patupilone versus paclitaxel by MTS(More)
