A biochemotherapy regimen with concurrent administration of cisplatin, vinblastine, temozolomide (Temodal), interferon-alfa and interleukin-2 for metastatic melanoma: a phase II study.
Binding studies indicated the presence of 2,980 +/- 170 receptors per cell, each with an apparent Kd of (8.4 +/- 1.3) X 10(-11) M. Results from competitive binding studies suggested that Hs294T cells possess at least two types of IFN receptors: one which binds IFN-alpha A and IFN-beta 1 and another to which IFN-gamma binds.
Direct intratumoral injection of 100 microg of a IFN-omega pDNA DMRIE/DOPE complex (1:1 DNA:DMRIE mass ratio) for 6 consecutive days resulted in a significant reduction in the tumor volume of NIH: OVCAR-3 ovarian carcinoma or A375 melanoma (P = 0.02).IFN-omega pDNA delivered by i.m. injection also had an antitumor effect.
Evaluation of NOS1 levels in melanomas and IFN responsiveness of purified PBMCs from patients indicated a negative correlation between NOS1 expression in melanomas and the responsiveness of PBMCs to IFN-α.
In a previous study on melanoma cell lines we found that greatest sensitivity to IFN was found in cell lines with the greatest number of copies of chromosome 9p, where the IFN gene family is located.
In the molecularly defined low-risk subgroup, patients treated with high-dose IFN had a significantly improved RFS compared with patients in the other two subgroups (<i>P</i> < 0.05).<b>Conclusions:</b> These results validate the independent impact of combined expression levels of SPP1, RGS1, and NCOA3 on survival of melanoma in a prospectively collected cohort.<i></i>.
In these contexts, targeted overexpression of hPNPase(old-35) might be a novel therapeutic strategy for c-myc-overexpressing and IFN-resistant tumors, such as melanomas.
Infection by measles virus (MV) induces type I IFN via the retinoic acid-inducible gene I/melanoma differentiation-associated gene 5/mitochondrial antiviral signaling protein (MAVS) pathway in human cells.
LOH was detected in 10 out of 27 informative naevi (37%) at D9S171 and in eight out of 19 (42%) at IFNA in the dissected naevus cell clusters, and in nine out of 27 (33%) at D9S171 and seven out of 19 (36%) at IFNA in the associated melanomas.
Low-dose outpatient chemobiotherapy with temozolomide, granulocyte-macrophage colony stimulating factor, interferon-alpha2b, and recombinant interleukin-2 for the treatment of metastatic melanoma.
Mice incapable of downregulating the IFN receptor and Ch25h were resistant to TEV uptake, TEV-induced pre-metastatic niche, and melanoma lung metastases; however, ablation of Ch25h reversed these phenotypes.
Our results suggest that CSF-470 vaccine plus BCG plus GM-CSF can significantly prolong, with lower toxicity, the DMFS of high-risk CM pts with respect to medium-dose IFN-α2b.
Patients who undergo surgical excision of stage III MM appear to enjoy prolonged DFS and OS when treated with TIL + IFN-<i>α</i> compared to IFN-<i>α</i> alone.
Poly I:C was not able to induce melanocytes or melanoma cells to produce detectable amounts of IFN-alpha protein, but able to induce a significant amount of IFN-beta in melanocytes and two of the melanoma cell lines: MMAc and VMRC-MELG.
Randomized trial of dacarbazine versus bleomycin, vincristine, lomustine and dacarbazine (BOLD) chemotherapy combined with natural or recombinant interferon-alpha in patients with advanced melanoma.
