A recombinant human RNASET2 glycoprotein with antitumorigenic and antiangiogenic characteristics
Authors: Smirnoff Patricia , Roiz Levava , Angelkovitch Boaz , Schwartz Betty , Shoseyov Oded
Published: November 2006

BACKGROUND.

Human RNASET2 is a T2‐RNase glycoprotein encoded by the RNASET2 gene, which is located on chromosome 6 (6q27). Deletion in 6q27 is associated with several human malignancies.

BACKGROUND.

A synthetic RNASET2 gene that was optimized for expression in the yeast Pichia pastoris was designed according to the cDNA sequence and was cloned under the control of the methanol‐induced promoter fused to the α‐mating secretion peptide. The recombinant protein was purified from the culture supernatant of transformed P. pastoris through an affinity Sepharose‐concanavalin A column. Actin‐binding activity was examined by membrane blotting using monoclonal mouse antiactin immunoglobulin M and by cross‐linking in solution to G‐actin using 1‐[3‐(dimethylamino)propyl]‐3‐ethyl‐carboimide methiodide. The antiangiogenic activity of RNASET2 (from 0.5 μM to 10 μM) was assessed by a human umbilical vein endothelial (HUVE) cell assay in the presence of 1 μg/mL angiogenin, basic fibroblast growth factor (bFGF), or recombinant human vascular endothelial growth factor (VEGF). Cell colony formation was examined in human colon HT29 cancer cells to assess the antitumorigenic activity of RNASET2 or the enzymatic‐inactivated RNASET2 (EI‐RNASET2) (1 μM each). In an athymic mouse xenograft model, LS174T human cancer cells were injected subcutaneously. When tumors were palpable, the mice were treated for 3 weeks with RNASET2 (1 mg/kg), paclitaxel (10 mg/kg or 15 mg/kg), or a combination of the 2 drugs.

RESULTS.

The recombinant RNASET2 was identified as a 27‐kilodalton glycoprotein that possessed the ability to bind actin in vitro. RNASET2 significantly inhibited clonogenicity in HT29 cells. EI‐RNASET2 produced a similar effect, suggesting that its antitumorigenic activity is unrelated to its RNase activity. In HUVE cells, RNASET2 inhibited angiogenin‐, bFGF‐, and VEGF‐induced tube formation in a dose‐dependent manner. In athymic mice, RNASET2 inhibited the development of an LS174T‐derived xenograft by 40%. A synergistic effect was obtained with combined RNASET2 and paclitaxel treatments.

CONCLUSIONS.

The current results suggested that RNASET2 represents a new class of antitumorigenic and antiangiogenic drugs, and the findings of this study emphasize the advantage of using agents like RNASET2 in combined therapy. Cancer 2006. © 2006 American Cancer Society.
Multicenter, noncomparative study of caspofungin in combination with other antifungals as salvage therapy in adults with invasive aspergillosis

Published: November 2006

BACKGROUND.

Caspofungin inhibits synthesis of β‐1,3‐glucan, an essential component of the Aspergillus cell wall. This echinocandin has demonstrated efficacy (45% success) as salvage monotherapy of invasive aspergillosis (IA). Interest remains as to whether caspofungin, in combination with other antifungal classes, can improve the efficacy against IA.

METHODS.

The study involved 53 adults with documented IA who were refractory to or intolerant of standard antifungal therapy and received caspofungin and 1 other mold‐active antifungal agent (at the investigator's discretion). Efficacy was assessed by signs, symptoms, and radiographs at the end of combination therapy and Day 84 after combination therapy initiation. Favorable (complete or partial) responses required significant clinical and radiographic improvement. Diagnoses and outcomes were assessed by an independent expert.

RESULTS.

Among the 53 patients enrolled the most common underlying diseases were acute leukemia (53%), lymphoma (11%), and chronic leukemia (6%). Pulmonary aspergillosis (81%) was the most common site, and most patients (87%) were refractory to prior therapy. Success at the end of combination therapy and Day 84 was 55% (29/53) and 49% (25/51), respectively. Fifty‐seven percent of patients with neutropenia and 54% who received an allogeneic hematopoietic stem cell transplant responded favorably. Survival at Day 84 was 55%. Combination therapy, dosed on average for 31.3 days, was well tolerated. Two (4%) serious drug‐related adverse events, both attributed to voriconazole, occurred. None of the patients discontinued caspofungin due to toxicity.

CONCLUSIONS.

Caspofungin in combination with a triazole or polyene was an effective alternative as salvage therapy for patients with recalcitrant Aspergillus infections. Cancer 2006. © 2006 American Cancer Society.
Cisplatin and gemcitabine with either vinorelbine or paclitaxel in the treatment of carcinomas of unknown primary site
Authors: Palmeri Sergio , Lorusso Vito , Palmeri Laura , Vaglica Marina , Porta Camillo , Nortilli Rolando , Ferraú Francesco , Comella Giuseppe , Massidda Bruno , Danova Marco
Published: November 2006

BACKGROUND.

To date, the standard treatment for patients who have carcinoma of unknown primary site has not been established.

METHODS.

In this randomized Phase II study, 66 previously untreated patients (33 patients per arm) with carcinomas of unknown primary site received cisplatin (35 mg/m2) and gemcitabine (1000 mg/m2) with either paclitaxel (70 mg/m2) or vinorelbine (25 mg/m2), and all drugs were administered intravenously on Days 1 and 8 of a 21‐day cycle. Twenty‐nine patients (44%) presented with ≥2 involved sites. The pathologic diagnosis was mainly adenocarcinoma (48 patients; 72.7%) and squamous carcinoma (7 patients; 10.6%).

RESULTS.

In the first arm, 16 patients (48.5%) experienced an objective response, and 9 patients (27.2%) had disease stabilization. In the vinorelbine‐containing arm, 14 patients (42.3%) experienced an objective response, and 8 patients (24.2%) had disease stabilization. The median response duration and the median time to progression were similar in both treatment arms; the median overall survival was 9.6 months (95% confidence interval, 7.11–12.09 months) for patients who received the cisplatin/gemcitabine/paclitaxel regimen and 13.6 months (95% confidence interval, 6.61–20.59 months) for patients who received the vinorelbine combination. Grade 3 and 4 toxicities were more frequent in the paclitaxel‐containing arm.

CONCLUSIONS.

Both combinations satisfied the 2‐step design, demonstrating antitumor activity without relevant differences in response rates or response duration; however, the vinorelbine‐containing regimen yielded superior results both in terms of overall survival (13.6 months vs 9.6 months) and in terms of treatment tolerability. Therefore, according to a pick the winner attitude, the combination of cisplatin/gemcitabine/vinorelbine may be considered in the design of future randomized, Phase III trials for patients with carcinomas of unknown primary site.

High‐dose therapy and autologous stem‐cell transplantation can improve event‐free survival for indolent lymphoma
Authors: Vignot Steéphane , Mounier Nicolas , Larghero Jeérôme , Brice Pauline , Quero Laurent , de Bazelaire Ceédric , Ertault Marjan , Brière Josette , Madelaine Isabelle , Gisselbrecht Christian
Published: November 2006

BACKGROUND.

High‐dose therapy (HDT) and autologous stem‐cell transplantation (ASCT) remain controversial for indolent lymphoma patients.

METHODS.

The study was designed to evaluate the benefit of this strategy by retrospectively comparing for each patient the event‐free survival (EFS) after ASCT with the duration of the disease phase just before the phase including ASCT (ie, the last qualifying phase, LQP).

RESULTS.

A total of 109 indolent lymphoma (mostly follicular lymphoma) patients were treated with HDT and ASCT. Before ASCT, patients experienced a median of 2 disease phases (range, 1–4). After a median 5‐year follow‐up from ASCT, overall survival was 67% and EFS was 43%. When each of the 92 patients experiencing recurrence was taken as her/his own control, EFS was longer after ASCT than the duration of LQP (62%, P < .01). During LQP, 86 patients (93%) experienced recurrence in less than 5 years, compared with only 58 (63%) who experienced recurrence in the 5 years after ASCT (P < .01).

CONCLUSION.

HDT and ASCT can significantly increase EFS in comparison with the duration of the LQP for indolent lymphoma patients and can change disease course. This methodology has been found useful for evaluating new strategies, especially with monoclonal antibodies. Cancer 2007. © 2006 American Cancer Society.
Neural specialization for hovering in hummingbirds: Hypertrophy of the pretectal nucleus lentiformis mesencephali
Authors: Iwaniuk Andrew N. , Wylie Douglas R.W.
Published: November 2006

Hummingbirds possess an array of morphological and physiological specializations that allow them hover such that they maintain a stable position in space for extended periods. Among birds, this sustained hovering is unique to hummingbirds, but possible neural specializations underlying this behavior have not been investigated. The optokinetic response (OKR) is one of several behaviors that facilitates stabilization. In birds, the OKR is generated by the nucleus of the basal optic root (nBOR) and pretectal nucleus lentiformis mesencephali (LM). Because stabilization during hovering is dependent on the OKR, we predicted that nBOR and LM would be significantly enlarged in hummingbirds. We examined the relative size of nBOR, LM, and other visual nuclei of 37 species of birds from 13 orders, including nine hummingbird species. Also included were three species that hover for short periods of time (transient hoverers; a kingfisher, a kestrel, and a nectarivorous songbird). Our results demonstrate that, relative to brain volume, LM is significantly hypertrophied in hummingbirds compared with other birds. In the transient hoverers, there is a moderate enlargement of the LM, but not to the extent found in the hummingbirds. The same degree of hypertrophy is not, however, present in nBOR or the other visual nuclei measured: nucleus geniculatus lateralis, pars ventralis, and optic tectum. This selective hypertrophy of LM and not other visual nuclei suggests that the direction‐selective optokinetic neurons in LM are critical for sustained hovering flight because of their prominent role in the OKR and gaze stabilization.

Epidermal growth factor receptor in adult retinal neurons of rat, mouse, and human
Authors: Chen Huiyi , Liu Bin , Neufeld Arthur H.
Published: November 2006

During development, the epidermal growth factor receptor (EGFR) regulates proliferation and differentiation of many types of cells, including precursors of neurons and glia. In the adult, EGFR continues to drive the growth and differentiation of epithelial cells but is absent from glia in the CNS. However, the localization and functions of EGFR in adult neurons are not well defined. By using immunohistochemistry and Western blotting, we have identified EGFR and its ligands in adult retinal ganglion cells in the normal rat, mouse, and human retina. EGFR and its ligands were also present in certain other adult retinal neurons, for example, horizontal cells and amacrine cells, and had different distribution patterns among these species. In addition, we found that EGFR was expressed in the rat retinal ganglion cell line RGC‐5. One of the EGFR ligands, EGF, caused a cell shape change and increased neurofilament phosphorylation in RGC‐5 cells. The expression of EGFR in postmitotic, terminally differentiated adult retinal neurons suggests that EGFR has pleiotropic functions. In addition to the conventional mitogenic role in adult epithelial cells, EGFR must serve a different, nonmitogenic function in adult neurons. Our work localizes EGFR and its ligands in the adult retinas of several species as a step toward investigating the nonmitogenic functions of EGFR in adult neurons. J. Comp.

The present report compares the morphology of callosal axon arbors projecting from and to the hind‐ or forelimb representations in the primary somatosensory cortex (SI) of the agouti (Dasyprocta primnolopha), a large, lisencephlic Brazilian rodent that uses forelimb coordination for feeding. Callosal axons were labeled after single pressure (n = 6) or iontophoretic injections (n = 2) of the neuronal tracer biotinylated dextran amine (BDA, 10 kD), either into the hind‐ (n = 4) or forelimb (n = 4) representations of SI, as identified by electrophysiological recording. Sixty‐nine labeled axon fragments located across all layers of contralateral SI representations of the hindlimb (n = 35) and forelimb (n = 34) were analyzed. Quantitative morphometric features such as densities of branching points and boutons, segments length, branching angles, and terminal field areas were measured. Cluster analysis of these values revealed the existence of two types of axon terminals: Type I (46.4%), less branched and more widespread, and Type II (53.6%), more branched and compact. Both axon types were asymmetrically distributed; Type I axonal fragments being more frequent in hindlimb (71.9%) vs. forelimb (28.13%) representation, while most of Type II axonal arbors were found in the forelimb representation (67.56%). We concluded that the sets of callosal axon connecting fore‐ and hindlimb regions in SI are morphometrically distinct from each other. As callosal projections in somatosensory and motor cortices seem to be essential for bimanual interaction, we suggest that the morphological specialization of callosal axons in SI of the agouti may be correlated with this particular function.
