    Opis:
    Supercoiled state corresponds to the active form for plasmid applications. The relaxed circular form of plasmids is often inactive or poorly active. To obtain significant amounts of almost fully supercoiled DNA, we modified the standard protocol of a commercially available Qiagen plasmid purification kit. Our changes led to isolation of almost 100% of the plasmids in the supercoiled state. The modified protocol was used to purify different plasmids with consistent results. The purified plasmids maintain supercoiled state for about two months. The modified protocol is very advantageous because it allows easy DNA production with high degree of supercoiled form at low cost.

    Opis:
    Gel filtration and velocity of sedimentation analyses on native and on lysine- and arginine- modified forms of the annelid worm Chaetopterus variopedatus sperm H1 histone indicate that anion-mediated lysine - arginine interactions play a relevant role in the stabilization of the oligomeric states of the molecule. CD spectroscopy shows that phosphate anions are at least an order of magnitude more efficient than chloride as negatively charged groups connecting H1 lysines and arginines. Acetylation of lysines, although not altering grossly the H1 properties, causes a tenfold decrease of the structuring efficiency of phosphates. This suggests that DNA phosphates may be sandwiched between lysine and arginine groups of H1 histone when this molecule binds to chromatin, constituting a relevant parameter for the reciprocal stabilization of the protein and of the chromatin higher order structures.

    Opis:
    Self-association of histones H1 from calf thymus and from sperm of the marine worm Chaetopterus variopedatus was studied on native and glutaraldehyde cross-linked molecules by PAGE and by salt-induced turbidity measurements. Multiple polymers were generated by native sperm histone H1-like after glutaraldehyde cross-linking while the same treatment on its lysine- or arginine-modified derivatives and on somatic histone H1 failed to induce polymerization. This result suggests the relevance of arginine content in the formation of histone H1-like polymers particularly because Chaetopterus variopedatus and calf thymus histones H1 have similar content of lysine but different K/R ratio (2 and 15, respectively). Salt-induced turbidity experiments confirmed the high tendency of sperm histone H1-like to form oligomers, particularly in the presence of phosphate ions. Native PAGE analysis in the presence of phosphate supported this hypothesis. The reported results suggest that phosphate ions connecting lysine and arginine side chain groups contribute to the interaction of sperm histone H1-like with DNA in chromatin and play a key role in organization and stabilization of the chromatin higher order structures.

    Opis:
    Methylation of specific lysine residues in histone tails has been proposed to function as a stable epigenetic marker that directs biological functions altering chromatin structure. Recent findings have implicated alteration in heterochromatin formation as a contributing factor in cancer development. In order to verify whether changes in the overall level of H3K4 histone methylation could be involved in oral squamous carcinoma, the levels of H3K4me1, me2 and me3 were measured in oral squamous carcinoma, leukoplakias and normal tissues. The levels of H3K4me2 and me3 were significantly different in oral squamous cell carcinoma in comparison with normal tissue: the level of H3K4me2 was increased while that of H3K4me3 decreased. No significant differences could be found between the two types of tissues in the level of H3K4me1. A similar trend was found in the leukoplakias that appeared more like the pathological than normal tissue. These results support the idea that alteration of chromatin structure could contribute to oncogenic potential.

    Opis:
    Here we report the industrial pollution effects due to cadmium on the reproductive health of Mytilus galloprovincialis. Mussels were removed from the biofouling of a Conatex panel after one year exposition at a polluted site near a disposal metallurgical factory. A high cadmium bioaccumulation was observed in the testis of mussels housed at the polluted site, with respect to a control site, as determined by inductively coupled plasma-mass spectrometry, along with a 10 fold increase in metallothionein 20 kDa gene (mt20) expression levels determined by qPCR. Furthermore, mussels transferred into laboratory tanks from the reference site, and exposed to 1.5, 5 and 10 µM CdCl2, revealed a 1.7, 3.2 and 4.5 fold expression increase in the testis mt20, respectively, and a positive correlation with cadmium bioaccumulation was found. To evaluate a potential detrimental risk of such alterations on spermatozoa, we carried out electrophoretic analyses on their protamine-like proteins. As determined by AU-PAGE, after 1.5 µM CdCl2 exposure, protamine-like proteins also display major alterations with respect to those obtained after 5 and 10 µM CdCl2 exposure. All protamine-like proteins isolated from the polluted biofouling were in an aggregated form and displayed the same reduced DNA binding affinity of the protamine-like proteins obtained after 1.5 µM CdCl2 as demonstrated EMSA with sperm genomic DNA. Our results contribute to the studies concerning cadmium induced testis alterations and highlight protamine-like proteins' analysis as an emerging biotechnique for cadmium impact assessment on Mytilus galloprovincialis, for the sensitivity of the in vivo and in vitro changes of protamine-like proteins' state and their DNA binding affinity.
