Systemic blockade of ACVR2B ligands prevents chemotherapy-induced muscle wasting by restoring muscle protein synthesis without affecting oxidative ca…

2016

AbstractDoxorubicin is a widely used and effective chemotherapy drug. However, cardiac and skeletal muscle toxicity of doxorubicin limits its use. Inhibiting myostatin/activin signalling can prevent muscle atrophy, but its effects in chemotherapy-induced muscle wasting are unknown. In the present study we investigated the effects of doxorubicin administration alone or combined with activin receptor ligand pathway blockade by soluble activin receptor IIB (sACVR2B-Fc). Doxorubicin administration decreased body mass, muscle size and bone mineral density/content in mice. However, these effects were prevented by sACVR2B-Fc administration. Unlike in many other wasting situations, doxorubicin indu…

3D polymeric supports promote the growth and progression of anaplastic thyroid carcinoma.

2020

Abstract Anaplastic thyroid carcinoma (ATC) is a rare and aggressive malignancy that accounts for the majority of deaths from all thyroid cancers. ATC exhibits invasiveness and highly resistance to conventional therapies which include cytotoxic chemotherapy, the combination of BRAF and MEK inhibition and, more recently, immunotherapies, that have shown promising but still limited results. A growing knowledge on ATC tumor biology is needed for developing more effective therapies with significant better survival. Researchers have begun to utilize 3D models to culture cancer cells for in vitro studies. In this work, C643 ATC cell line was cultured on polymeric scaffolds with high-interconnecte…

Polyoxypregnanes as safe, potent, and specific ABCB1-inhibitory pro-drugs to overcome multidrug resistance in cancer chemotherapy in vitro and in vivo

2021

Multidrug resistance (MDR) mediated by ATP binding cassette subfamily B member 1 (ABCB1) is significantly hindering effective cancer chemotherapy. However, currently, no ABCB1-inhibitory drugs have been approved to treat MDR cancer clinically, mainly due to the inhibitor specificity, toxicity, and drug interactions. Here, we reported that three polyoxypregnanes (POPs) as the most abundant constituents of Marsdenia tenacissima (M. tenacissima) were novel ABCB1-modulatory pro-drugs, which underwent intestinal microbiota-mediated biotransformation in vivo to generate active metabolites. The metabolites at non-toxic concentrations restored chemosensitivity in ABCB1-overexpressing cancer cells v…

Cytotoxicity of cucurbitacin E from Citrullus colocynthis against multidrug-resistant cancer cells

2019

Abstract Background Cucurbitacin E (CuE) is an oxygenated tetracyclic triterpenoid isolated from the fruits of Citrullus colocynthis (L.) Schrad. Purpose This study outlines CuE's cytotoxic activity against drug-resistant tumor cell lines. Three members of ABC transporters superfamily, P-glycoprotein (P-gp), breast cancer resistance protein (BCRP) and ABCB5 were investigated, whose overexpression in tumors is tightly linked to multidrug resistance. Further factors of drug resistance studied were the tumor suppressor TP53 and the epidermal growth factor receptor (EGFR). Methods Cytotoxicity assays (resazurin assays) were used to investigate the activity of Citrullus colocynthis and CuE towar…

Response-guided ABVD chemotherapy plus involved-field radiation therapy for intermediate-stage Hodgkin lymphoma in the pre-positron emission tomograp…

2009

Abstract Purpose In the pre—positron emission tomography era, the Gruppo Italiano Studio Linfomi (GISL) investigated the feasibility and efficacy of a treatment based on a response-tailored number of doxorubicin/bleomycin/vinblastine/dacarbazine (ABVD) courses in 218 intermediate-stage Hodgkin lymphoma patients. Patients and Methods Patients with stage I/II showing at least one adverse prognostic factor and stage IIIA without adverse prognostic factors were recruited. Treatment included a first step of 3 ABVD courses, followed by an early-restaging. Patients in CR/CRu received 1 additional ABVD cycle, patients in PR received 3 more ABVD, and nonresponder patients went off study. Involved-fi…

Burkitt lymphoma associated with human immunodeficiency virus infection and pulmonary tuberculosis: A case report.

2019

Abstract Introduction: The association of human immunodeficiency virus (HIV) infection with Burkitt lymphoma is related to the presence of Epstein Barr virus infection and the impact of the HIV antigen on the expansion of B-polyclonal cells. In Southeast Europe, the association is rare, and recognizing this is important in the therapeutic decision to increase patient survival rate. The association of HIV with Burkitt lymphoma and tuberculosis is even more rarely described in the literature. Patient concerns: We present the case of a 40-year-old patient who presented with a 3-week history of fever (max. 38.7 °C), painful axillary swelling on the right side, lumbar pain, gait disorders, heada…

A phase II study of pegylated liposomal doxorubicin oxaliplatin and cyclophosphamide as second-line treatment in relapsed ovarian carcinoma

2006

We carried out a phase II nonrandomized study to examine the level of activity of oxaliplatin, pegylated liposomal doxorubicin, and cyclophosphamide in a patient population with relapsed ovarian cancer pretreated with platinum derivatives and paclitaxel. Patients received oxaliplatin (85 mg/m2), pegylated liposomal doxorubicin (30 mg/m2), and cyclophosphamide (750 mg/m2). A total of 49 patients (39 assessable for toxicity and response) were enrolled in this trial. Neutropenia grade 3 was observed in six patients (15%) and anemia grade 3 in one patient (0.2%). Fatigue grade 1–2 occurred in 26 patients (66%), nausea/vomiting grade 1 in 23 patients (58%), and alopecia grade 1–2 in 19 patients …

Polyaspartamide-Doxorubicin Conjugate as Potential Prodrug for Anticancer Therapy

2015

Purpose To synthesize a new polymeric prodrug based on ?,?- poly(N-2-hydroxyethyl)(2-aminoethylcarbamate)-d,l-aspartamide copolymer bearing amine groups in the side chain (PHEA-EDA), covalently linked to the anticancer drug doxorubicin and to test its potential application in anticancer therapy. Methods The drug was previously derivatized with a biocompatible and hydrophilic linker, leading to a doxorubicin derivative highly reactive with amino groups of PHEA-EDA. The PHEAEDA- DOXO prodrug was characterized in terms of chemical stability. The pharmacokinetics, biodistribution and cytotoxicity of the product was investigated in vitro and in vivo on human breast cancer MCF-7 and T47D cell lin…
