In the last years an increasing incidence of cardiovascular diseases (CVD) has been reported in young adults (18-45 yrs), probably accounted by the significant increase in CV risk (CVR) factors. Observational and interventional studies, mainly focused on middle-aged and elderly men, demonstrated that metabolic CVR (mCVR) factors and CVD manifestations are common in hypogonadal men and, conversely, testosterone deficiency is highly prevalent in metabolic disorders; the lack of ...

Potential role of vitamin D in restoring sensitivity to mTOR inhibitors in hepatocellular carcinoma (HCC): 1,25(OH)vitamin D (VitD) reverts everolimus (EVE) resistance in a hcc cell line

Pivonello Claudia , Provvisiero Donatella Paola , Negri Mariarosaria , Gennaro Gilda Di , de Angelis Cristina , Simeoli Chiara , Galdiero Giacomo , Martino Maria Cristina De , Colao Annamaria , Pivonello Rosario

HCC is a difficult-to-treat- cancer with poor prognosis. Despite EVOLVE-1 trial demonstrated that EVE did not improve overall survival in molecularly and clinically unselected patients with advanced sorafenib resistant HCC, in selected patients, the established antitumor effect of EVE could make this drug a potential adjuvant therapy. Unfortunately, the acquired EVE resistance due to the tumour adaptation to chronic drug use is a current challenge. VitD has been deemed as pote...

Dual targeting of PIK3/AKT/mTOR and IGF1/KRAS/BRAF pathways in an in vitro model of ovarian cancer: strategies for cell proliferation control

Ovarian cancer (OC) is the most lethal gynecological cancer. Debulking surgery and platinum-based chemotherapy are the cornerstone of OC management; however, after a partial initial response, tumors invariably relapse. Therapeutic approaches should account for interindividual heterogeneity since OC histiotypes show distinct genetic profile. A2780 cell line has been annotated as high grade serous ovarian cancer (HGSOC); nevertheless, recent research underlined that the genetic ...

Potential role of vitamin D in restoring sensitivity to mTOR inhibitors in hepatocellular carcinoma (HCC): 1,25(OH)vitamin D (VITD) reverts everolimus (EVE) resistance in a HCC cell line

HCC is a difficult-to-treat- cancer with poor prognosis. The recent EVOLVE-1 trial demonstrated that EVE did not improve overall survival in molecularly and clinically unselected patients with advanced HCC resistant to sorafenib treatment. In selected patients, the well-established antitumor effect of EVE could make this drug a potential adjuvant therapy. Unfortunately, the acquired resistance to this molecule due to the tumor adaptation to chronic drug use is a current challe...

The role of dopamine pathway on human sperm: in vitro effect of dopamine receptor agonists and antagonists on sperm motility, kinetics and viability

de Angelis Cristina , Cariati Federica , Galdiero Giacomo , Coppola Giorgio , Galdiero Mariano , Salzano Ciro , Pivonello Claudia , Patalano Roberta , Alviggi Carlo , De Placido Giuseppe , Colao Annamaria , Pivonello Rosario

Dopamine has been found in both semen and oviductal fluid and dopamine receptors (DRs) have been detected in male genital tract and spermatozoa, suggesting that dopamine system may control important reproductive functions in humans. Dopamine improves sperm motility and viability in animal models, although the underlying molecular mechanisms have not been fully elucidated. The aims of this study were to investigate DRs expression in human spermatozoa and to evaluate the in ...

Fertility in acromegaly: A single center experience on female patients during active disease and after disease remission

Pirchiom Rosa , Auriemma Renata S. , Verde Nunzia , Garifalos Francesco , Castoro Michele , Galdiero Giacomo , Piscopo Mariangela , Pivonello Claudia , Colao Annamaria , Pivonello Rosario

Fertility represents a major concern in patients with acromegaly and the peculiar PCOS-like condition is commonly found in acromegalic women. The current retrospective study aimed at investigating gonadal function and fertility rate in acromegalic women with disease onset (DO) within the reproductive age. In 50 women hormonal parameters and gynecological ultrasound were evaluated at diagnosis (DD) and after disease control (DC). Data about menstrual disturbances (MD), pregnanc...

Morphostructural characterization of the testis in a large cohort of men living in highly polluted areas of Campania Region in south Italy: a focus on cadmium exposure

Garifalos Francesco , De Angelis Cristina , Di Nunzio Aldo , Menafra Davide , Castoro Michele , Verde Nunzia , Galdiero Giacomo , Piscopo Mariangela , Pivonello Claudia , Auriemma Renata Simona , Chiodini Paolo , Trifuoggi Marco , Colao Annamaria , Pivonello Rosario

Campania Region has been facing waste management crisis since 1980, characterized by urban, toxic and industrial waste illegal disposal, burying and incineration. Cadmium (Cd) is consistently shown to affect male reproductive function by multiple mechanisms, mostly elucidated in experimental models. The aim of the current single-center, observational, cross-sectional cohort study was to evaluate the prevalence of testis morphostructural alterations in a large cohort of men liv...
