Circular dichroism study of DNA binding by a potential anticancer peptide nucleic acid targeted against the MYCN oncogene
Authors: Faccini Andrea , Tortori Andrea , Tedeschi Tullia , Sforza Stefano , Tonelli Roberto , Pession Andrea , Corradini Roberto , Marchelli Rosangela 
Published: October 2007

AbstractThe interaction with DNA of a peptide nucleic acid (PNA) oligomer (16nt) conjugated with a nuclear localization signal (NLS) peptide, which was previously found to be able to inhibit tumor cell proliferation through block of transcription of the MYCN oncogene, was studied by UV and CD spectroscopy. While data obtained by UV were not conclusive, the use of circular dichroism gave clear‐cut evidence of the formation of a PNA:DNA duplex of exceptionally high stability (Tm ≥ 90°C). Using the same approach, the effect of mutations on DNA:PNA stability was evaluated, and was found in accordance with that expected for a Watson–Crick interaction. The role of the NLS peptide was evaluated by using a PNA lacking of this part, which gave rise to less stable PNA:DNA duplexes. Finally, a competition experiment carried out with a 26mer dsDNA, containing the target 16mer sequence in its middle region, in the presence of PNA‐NLS gave evidence for the formation of a ternary complex at 25°, while at higher temperature, the PNA:DNA duplex and the displaced homologous DNA strand were detected. The present results support the possibility of an analogous mechanism of action of this antitumor PNA in vivo. Chirality, 2008. © 2007 Wiley‐Liss, Inc.

Authors: Altundag Kadri , Bondy Melissa L. , Mirza Nadeem Q. , Kau Shu‐Wan , Broglio Kristine , Hortobagyi Gabriel N. , Rivera Edgardo 
Published: October 2007

AbstractBACKGROUND.Breast cancer is the second most common cause of central nervous system (CNS) metastases. Several risk factors for CNS metastases have been reported. The objective of the current study was to describe clinicopathologic characteristics and prognostic factors in breast cancer patients with CNS metastases.METHODS.The authors retrospectively evaluated clinical data from 420 patients who had been diagnosed with breast cancer and CNS metastasis between 1994 and 2004 at the University of Texas M. D. Anderson Cancer Center.RESULTS.The median age of the patients at the time of diagnosis of breast cancer was 45 years (range, 25–77 years). Premenopausal and postmenopausal patients were distributed equally. Most patients had invasive ductal histology (91.2%), grade 3 tumors (81.4%) (using the modified Black nuclear grading system), T2 tumor classification (40.1%), and N1 lymph node status (59.7%) diagnosis. Forty percent of patients had estrogen receptor (ER)‐positive disease, and 34% had progesterone receptor‐positive disease. HER‐2/neu status was recorded for only 248 patients, and 39% of the patients in that group had HER‐2/neu‐positive disease. The most common sites of first metastasis were liver, bone, and lung. CNS metastasis was the site of first recurrence in 53 patients (12%). In total, 329 patients had received either neoadjuvant treatment (113 patients) or adjuvant chemotherapy (216 patients). The majority of those patients (74.4%) had received anthracycline‐based regimens. Metastasis was solitary in 111 patients (26.4%), and 29 patients had only leptomeningeal metastases. The median time from breast cancer diagnosis to CNS metastasis was 30.9 months (range, from −5 months to 216.7 months). The median follow‐up after a diagnosis of CNS metastasis was 6 months (range, 7–95.9 months). In all, 359 patients died, and the overall median survival was 6.8 months. Only age at diagnosis and ER status were associated significantly with overall survival in the multivariate analysis.CONCLUSIONS.The current results indicated that the prognosis remains patients with breast cancer metastatic to the CNS. More effective treatment approaches are needed for patients with CNS metastases, even for those with favorable prognostic factors, such as ER‐positive tumors or younger age.

Survival improvements for advanced stage nonbronchioloalveolar carcinoma‐type nonsmall cell lung cancer cases with ipsilateral intrapulmonary nodules
Authors: Zell Jason A. , Ou S.‐H. Ignatius , Ziogas Argyrios , Anton‐Culver Hoda 
Published: October 2007

AbstractBACKGROUND.Survival improvements have been demonstrated for patients with bronchioloalveolar (BAC) nonsmall cell lung cancer (NSCLC) with intrapulmonary satellite T4 nodules compared with other patients with stage IIIB disease, and for ipsilateral intrapulmonary M1 tumors versus contralateral or distant metastasis. However, it is not known whether these differences are observed in patients with non‐BAC NSCLC.METHODS.A case‐only analysis of the U.S. Surveillance, Epidemiology, and End Results (SEER) data (1999–2003) was conducted. Overall survival (OS) and lung cancer‐specific survival (LCSS) univariate analyses were conducted using the Kaplan‐Meier method. Multivariate survival analyses were performed using Cox proportional hazards ratios.RESULTS.A total of 27,435 incident cases of histologically confirmed, advanced stage NSCLC were identified. Cases with stage IIIB NSCLC due to multiple lesions in the same lobe (n = 633) had a significantly improved median OS (21 months) and LCSS (31 months) compared with other cases with stage IIIB NSCLC (n = 7695), with an OS of 7 months and an LCSS of 9 months (P < .0001 for both comparisons). Among cases with stage IV NSCLC, those with intrapulmonary nodules (n = 3010) had a significantly improved median OS (9 months) and LCSS (10 months) compared with those with distant metastasis (n = 16,097), with an OS of 4 months and an LCSS of 5 months (P < .0001 for both comparisons). These survival differences persisted after adjustment for age, sex, ethnicity, surgery, and radiotherapy. Among cases with stage IV NSCLC, those with ipsilateral intrapulmonary nodules (n = 1120) had improved OS (12 months) compared with those with bilateral intrapulmonary nodules (n = 1890), with an OS of 7 months (P < .0001).CONCLUSIONS.Cases with stage IIIB and IV NSCLC with ipsilateral intrapulmonary nodules were found to have improved survival outcomes compared with other cases with stage IIIB and IV disease. The results of the current study add additional support for modifications to the current NSCLC staging system. Cancer 2008. © 2007 American Cancer Society.
CMV‐specific central memory T cells reside in bone marrow

Published: October 2007

AbstractCMV‐specific CD8+ T cell responses in peripheral blood (PB) are characterized by a preponderance of effector and effector memory T cells. CMV‐specific central memory T cells (TCM), which are considered crucial in maintaining long‐term immunity, are rarely detectable in PB. In this study we have analyzed differentiation and function of CMV pp65‐specific CD8+ T cells in paired samples of human PB and BM using intracellular cytokine and tetramer staining. Overall frequencies of CMV pp65‐specific T cells were similar in PB compared to BM; however, CMV‐specific CD45RA–CCR7+ TCM were almost exclusively detectable in BM, which was not related to a general accumulation of TCM in BM. In vitro, CMV‐specific T cells could be more efficiently expanded from BM (median 128‐fold, n=6) than from PB (median 72‐fold, p=0.01). Taken together, these data show that the BM is a compartment harboring CMV‐specific TCM and underline the concept of the BM as a secondary immune organ. CMV specific BM‐derived TCM might be a valuable source for generating T cells for adoptive transfer.
New Polymorphs of Magnesium‐Based Metal–Organic Frameworks Mg3(ndc)3 (ndc = 2,6‐Naphthalenedicarboxylate)
Authors: Senkovska Irena , Fritsch Julia , Kaskel Stefan 
Published: October 2007

AbstractTwo new magnesium 2,6‐naphthalenedicarboxylate (ndc) metal–organic frameworks, [Mg3(ndc)3(dif)4] (1) (dif = N,N‐diisopropylformamide) and [Mg3(ndc)3(dmf)2(CH3OH)(H2O)](dmf) (2 = TUDMOF‐3) (dmf = N,N‐dimethylformamide), have been synthesised under solvothermal conditions from Mg(NO3)2·6H2O and pure 2,6‐naphthalenedicarboxylic acid. According to single‐crystal X‐ray crystallographic studies, complex 1 crystallises in the space group P21/n [a = 14.769(3) Å, b = 13.325(3) Å, c = 17.998(4) Å, β = 108.67(2)°] and complex 2 in the space group P$\bar {1}$ [a = 11.1116(11) Å, b = 12.6229(13) Å, c = 17.800(2) Å, α = 88.568(14)°, β = 83.833(13)°, γ = 70.167(11)°]. The structures of compounds 1 and 2 consist of trinuclear magnesium clusters connected to six dicarboxylate ligands; for 2, the clusters act as distorted octahedral nodes to give a 3D network. In contrast, the trinuclear clusters in 1 act as pseudo‐planar‐hexagonal nodes to give a 2D network assembly. According to nitrogen and hydrogen physisorption measurements at 77 K for compounds 1 and 2, TUDMOF‐3 has a permanent porosity with a Langmuir surface area of 632 m2 g–1, a specific pore volume of 0.21 cm3 g–1 and a hydrogen storage capacity of 1.23 wt.‐% at 77 K and 1 bar, whereas compound 1 is not porous.(© Wiley‐VCH Verlag GmbH & Co.

Flexible CuI–Thiolate Clusters with Relevance to Metallothioneins
Authors: Maiti Biplab K. , Pal Kuntal , Sarkar Sabyasachi 
Published: October 2007

AbstractSimple Cu–thiolate chemistry was developed to demonstrate the presence of copper clusters with {Cu4S6}, {Cu5S7} and {Cu6S4} cores in relevance to copper‐containing metallothioneins. The new hexanuclear tricoordinate triply bridging thiolatocopper(I) clusters [NEt4]4[Cu6(SPh)4Cl6] (1) and[NEt4]4[Cu6(SPh)4Br6] (2) were synthesized from the soup of polymeric [CuISPh]n and quaternary ammonium halide. These complexes readily converted into [Et4N]2[Cu5(SPh)7] (3) and [Et4N]2[Cu4(SPh)6] (4) in the presence of excess amounts of thiol. All are structurally characterized by single‐crystal X‐ray crystallography and these smaller clusters may be inscribed into the structurally characterized larger cluster {Cu8S10} obtained from synthetic copper yeast metallothioneins. Like Cu–MT proteins, all these clusters show photoluminescence around 560 nm on excitation at 350 nm, and these emission spectra are completely quenched by molecular oxygen. Variable copper stoichiometry and the interconversion of only monodentate thiolate ligands in these clusters convey the importance of flexibility, which is relevant to metallothioneins.

AbstractThe influence and reactivity of fluorine‐containing Lewis acids such as neat BF3, BF3·OEt2, and B(C6F5)3 on Me3SiCl elimination in (Me3Si)2N–N(SiMe3)–PCl2 was investigated. The reaction with B(C6F5)3 resulted in the formation of a novel diazadiphosphetidine with a phosphorus(III) atom attached to a pentafluorophenyl group, which can be regarded as a formal NNP fragment insertion into a B–C bond.(© Wiley‐VCH Verlag GmbH & Co.
