El secreto son los &lt;span style="font-weight: bold;"&gt;desmosomas&lt;/span&gt;, una suerte de anclajes que "enganchan" unas células con otras. Un estudio publicado en la revista &lt;span style="font-style: italic;"&gt;Nature &lt;/span&gt;ha conseguido fotografiar estas estructuras. Los anclajes de las células deben su capacidad de unión a las&lt;span style="font-weight: bold;"&gt; caderinas&lt;/span&gt;, una familia de moléculas de adhesión que resultan esenciales para preservar la integridad de los tejidos. Investigadores del Laboratorio de Biología Molecular Europeo (EMBL) han conseguido visualizar estas proteínas en su medio natural gracias a una avanzada técnica microscópica, llamada &lt;span style="font-weight: bold;"&gt;tomografía por criogenización&lt;/span&gt;. Se toman imágenes desde diferentes puntos y un programa informático reconstruye en el ordenador una imagen tridimensional.&lt;br /&gt;"Literalmente, hemos congelado la muestra, de modo que nos intentamos asegurar que durante todo el proceso va a estar lo más cerca posible de su estado original", aclara el investigador español, encargado de crear el software que reconstruye las imágenes que se toman de las caderinas. Es la primera vez que se utiliza esta técnica para estudiar las estructuras que unen las células de la piel a ese nivel de resolución (es decir, a escala molecular). "Este es un hito real en dos aspectos", ha dicho Achilleas Frangakis, líder del grupo de investigación. "Nunca antes ha sido posible mirar en tres dimensiones un tejido tan cerca de su estado primitivo y a semejante resolución. Ahora podemos ver detalles a la escala de unas millonésimas partes de milímetro. De este modo hemos logrado una nueva visión de las interacciones de las moléculas que subyacen a la adhesión celular en los tejidos, un mecanismo que se ha cuestionado durante décadas", añade. Y lo que han visto es que las &lt;span style="font-weight: bold;"&gt;caderinas &lt;/span&gt;"se distribuyen de forma muy estructurada. &lt;span style="font-weight: bold;"&gt;Funcionan como una especie de velcro&lt;/span&gt;", aclara Castaño. A saber: &lt;span style="font-weight: bold;"&gt;cada célula tiene unos pequeños ganchitos (las caderinas) que serían como los pequeños pelos del velcro.

Se conocían diferentes piezas (detalles de proteínas concretas, su morfología global) pero no se había conseguido organizar la imagen total y precisa de esta estructura. El último número de la revista "&lt;span style="font-style: italic;"&gt;Nature&lt;/span&gt;" publica finalmente esta arquitectura.&lt;br /&gt;&lt;/div&gt;El resultado es una suerte de &lt;span style="font-weight: bold;"&gt;rosquilla multicolor&lt;/span&gt; (embebida en la membrana nuclear, dentro de los poros) en la que quedan ubicados los diferentes componentes de este complejo. Las &lt;span style="font-weight: bold;"&gt;proteínas &lt;/span&gt;forman un andamio que cubre la membrana nuclear, con un gran número de proteínas en su cara interna. Pese a su tamaño, "sólo consiste en unos cuantos módulos estructurales que recuerdan unos a otros", explican los autores. Lo más "llamativo", según sus propias palabras, es que este andamiaje está formado por &lt;span style="font-weight: bold;"&gt;pilares repetitivos&lt;/span&gt;. Hasta ahora se sabía que los poros nucleares están compuestos de ocho pilares, rodeando un tubo central (como si de un cilindro se tratase). Los autores se han encontrado ahora con una asombrosa simetría dentro de estos pilares: cada uno se compone de dos columnas simétricas, es decir, que los poros estarían formados por 16 columnas emparejadas. Este hallazgo da pistas sobre cómo pudo haber evolucionado de esta estructura. Asimismo, la estructura también contiene varios anillos internos y externos que conforman un andamiaje central que, según los autores, "probablemente tenga un papel clave para mantener la estabilidad de la membrana nuclear". La mayoría de las proteínas estructurales (bastante escasas, teniendo en cuenta la complejidad y tamaño del poro) se encuentran en la superficie de estos anillos. Las responsables del tráfico a través de estas compuertas (&lt;span style="font-weight: bold;"&gt;nucleoporinas&lt;/span&gt;) también se organizan de un modo bastante simple: "desordenadas nubes de filamentos que rellenan el canal central y las zonas próximas de la membrana, proyectándose al nucleoplasma y el citoplasma. Estas nubes actúan como una barrera selectiva para regular el tráfico", aclaran los autores. Columnas, pilares, anillos... "&lt;span style="font-weight: bold;"&gt;Como resultado, uno puede considerar que el complejo del poro nuclear está hecho de sólo unos cuantos módulos estructurales, cada uno formado de sólo dos o cuatro proteínas. Estos módulos recuerdan unos a otros, tanto por estar compuestos por proteínas homólogas como por su similar disposición&lt;/span&gt;", resumen los investigadores.&lt;br /&gt;Estudiar los poros nucleares resulta de sumo interés, tanto por su tamaño (es uno de los mayores complejos macromoleculares de la célula) como por la flexibilidad de sus componentes.&lt;br /&gt;&lt;/div&gt;&lt;p&gt;&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8195582002181546649-1490633068891603366?l=bio2bach.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://bio2bach.blogspot.com/feeds/1490633068891603366/comments/default' title='Enviar comentarios'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=8195582002181546649&amp;postID=1490633068891603366' title='0 comentarios'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/8195582002181546649/posts/default/1490633068891603366'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/8195582002181546649/posts/default/1490633068891603366'/><link rel='alternate' type='text/html' href='http://bio2bach.blogspot.com/2007/12/poros-nucleares.html' title='Poros Nucleares'/><author><name>emh</name><uri>http://www.blogger.com/profile/00615831767892978073</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='25' height='32' src='http://4.bp.blogspot.com/_sqpw7zMH3OU/SQQdfThstnI/AAAAAAAAArw/lvHoaGTqwcM/S220/EDU2.jpg'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://3.bp.blogspot.com/_sqpw7zMH3OU/R1uifVRk-nI/AAAAAAAAAVg/CsuVqg3Z4mI/s72-c/poros_nucl.jpg' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-8195582002181546649.post-5466007639758739902</id><published>2007-11-28T18:41:00.000+01:00</published><updated>2007-12-09T09:33:45.248+01:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='biomoléculas'/><title type='text'>Bioelementos, agua y disoluciones</title><content type='html'>&lt;div style="width: 425px;

como un tipo de difusión pasiva caracterizada por el paso del agua (disolvente) a través de la &lt;span style="font-weight: bold;"&gt;membrana semipermeable&lt;/span&gt; desde la solución más diluida a la más concentrada. Y se entiende por presión osmótica la presión que sería necesaria para detener el flujo de agua a través de la membrana semipermeable.&lt;br /&gt;La &lt;span style="font-style: italic;"&gt;membrana plasmática&lt;/span&gt; de la célula puede considerarse como una membrana semipermeable; por ello, las células de los organismos pluricelulares deben permanecer en equilibrio osmótico con los líquidos titulares que las bañan. Cuando la concentración de solutos de los fluidos extracelulares es igual a la concentración intracelular, ambas disoluciones son &lt;span style="font-weight: bold;"&gt;isotónicas&lt;/span&gt;, pero si los líquidos extracelulares aumentan su concentración, se hacen &lt;span style="font-weight: bold;"&gt;hipertónicos&lt;/span&gt; respecto a las células y, como consecuencia, las células pierden agua, se deshidratan y mueren (&lt;span style="font-style: italic;"&gt;plasmolisis&lt;/span&gt;). De modo similar, si los líquidos extracelulares se diluyen, se hacen &lt;span style="font-weight: bold;"&gt;hipotónicos&lt;/span&gt; respecto a las células, el agua tiende a pasar al protoplasma interior y las células se hinchan, se vuelven turgentes &lt;span style="font-style: italic;"&gt;(turgescencia&lt;/span&gt;) y llegan incluso a estallar (&lt;span style="font-style: italic;"&gt;hemólisis&lt;/span&gt;, en el caso de los eritrocitos), si no disponen de una pared  celulosa como los vegetales (ver animación &lt;a href="http://www.ac-creteil.fr/biotechnologies/doc_osmosis.htm"&gt;L'osmose&lt;/a&gt; realizado por Laurent Martorell, profesor de bioquímica).&lt;/div&gt;&lt;p style="text-align: justify;" class="MsoNormal"&gt;&lt;span style="" lang="ES-TRAD"&gt;&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8195582002181546649-3738908724639923363?l=bio2bach.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://bio2bach.blogspot.com/feeds/3738908724639923363/comments/default' title='Enviar comentarios'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=8195582002181546649&amp;postID=3738908724639923363' title='0 comentarios'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/8195582002181546649/posts/default/3738908724639923363'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/8195582002181546649/posts/default/3738908724639923363'/><link rel='alternate' type='text/html' href='http://bio2bach.blogspot.com/2007/11/smosis.html' title='Ósmosis'/><author><name>emh</name><uri>http://www.blogger.com/profile/00615831767892978073</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='25' height='32' src='http://4.bp.blogspot.com/_sqpw7zMH3OU/SQQdfThstnI/AAAAAAAAArw/lvHoaGTqwcM/S220/EDU2.jpg'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://2.bp.blogspot.com/_sqpw7zMH3OU/Rz32hhUoUMI/AAAAAAAAAMY/svLVAQc15Go/s72-c/osmosis.jpg' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-8195582002181546649.post-1838721409355463474</id><published>2007-11-16T13:22:00.000+01:00</published><updated>2008-12-10T13:54:51.843+01:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='actividades'/><category scheme='http://www.blogger.com/atom/ns#' term='orgánulos'/><title type='text'>Respiración Celular.

La meiosis, que comparte mecanismos con la mitosis pero que no debe confundirse con ella, produce células genéticamente distintas y, combinada con la fecundación, es el fundamento de la reproducción sexual.&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify;"&gt;Este proceso se lleva a cabo en dos divisiones nucleares y citoplasmáticas, llamadas, primera y segunda división meiótica o simplemente Meiosis I y Meiosis II. Ambas comprenden Profase, Metafase, Anafase y Telofase. Durante la meiosis I los miembros de cada par homólogo de cromosomas se unen primero y luego se separan y se distribuyen en diferentes núcleos. En la Meiosis II, las cromátidas hermanas que forman cada cromosoma se separan y se distribuyen en los núcleos de las células hijas. Entre estas dos etapas sucesivas no existe la etapa S (duplicación del ADN).&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify;"&gt;&lt;a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://www.pbs.org/wgbh/nova/baby/divi_flash.html"&gt;&lt;img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer;" src="http://1.bp.blogspot.com/_sqpw7zMH3OU/Rz0-bRUoUDI/AAAAAAAAALQ/ZqsnRSAWGEY/s200/meiosis1.jpg" alt="" id="BLOGGER_PHOTO_ID_5133327788499554354" border="0" /&gt;&lt;/a&gt;Los errores en la meiosis son responsables de las principales &lt;span style="font-weight: bold;"&gt;anomalías cromosómicas&lt;/span&gt;.

a partir de la información genética que les llega del ADN transcrita en forma de ARN mensajero (ARNm). Sólo son visibles al microscopio electrónico, debido a su reducido tamaño (29 nm en células procariotas y 32 nm en eucariotas). Bajo el microscopio electrónico se observan como estructuras redondeadas, densas a los electrones. Están en todas las células (excepto en los espermatozoides). Los ribosomas se elaboran en el núcleo pero desempeñan su función de síntesis de proteínas en el citoplasma. Están formados por &lt;span style="font-weight: bold;"&gt;ARN ribosómico&lt;/span&gt; (ARNr) y por proteínas. Estructuralmente, tienen &lt;span style="font-weight: bold;"&gt;dos subunidades&lt;/span&gt;. En las células, estos orgánulos aparecen en diferentes estados de disociación. Cuando están completos, pueden estar aislados o formando grupos (&lt;span style="font-weight: bold;"&gt;polisomas&lt;/span&gt;). También pueden aparecer asociados al retículo endoplasmático rugoso o a la membrana nuclear. En células eucariotas, los ribosomas del citoplasma se denominan 80 S. En mitocondrias y plastos de eucariotas así como en procariotas son 70 S. Tanto los ARNr como las subunidades de los ribosomas se suelen nombrar por su coeficiente de sedimentación en subunidades Svedberg.&lt;br /&gt;&lt;div style="text-align: center;"&gt;&lt;object width="320" height="266" class="BLOG_video_class" id="BLOG_video-ff14252fd6bcb5c4" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0"&gt;&lt;param name="movie" value="http://www.youtube.com/get_player"&gt;&lt;param name="bgcolor" value="#FFFFFF"&gt;&lt;param name="allowfullscreen" value="true"&gt;&lt;param name="flashvars" value="flvurl=http://v12.nonxt8.googlevideo.com/videoplayback?id%3Dff14252fd6bcb5c4%26itag%3D5%26app%3Dblogger%26ip%3D0.0.0.0%26ipbits%3D0%26expire%3D1331626443%26sparams%3Did,itag,ip,ipbits,expire%26signature%3D53920C3CB55F8187B0A106633E4CAF018586ED89.29C7FDCF513E38DCAC0E204B680D926547A13177%26key%3Dck1&amp;amp;iurl=http://video.google.com/ThumbnailServer2?app%3Dblogger%26contentid%3Dff14252fd6bcb5c4%26offsetms%3D5000%26itag%3Dw160%26sigh%3DRtH9VmLpPvmc_SPJaZCmMwXOKZs&amp;amp;autoplay=0&amp;amp;ps=blogger"&gt;&lt;embed src="http://www.youtube.com/get_player" type="application/x-shockwave-flash"width="320" height="266" bgcolor="#FFFFFF"flashvars="flvurl=http://v12.nonxt8.googlevideo.com/videoplayback?id%3Dff14252fd6bcb5c4%26itag%3D5%26app%3Dblogger%26ip%3D0.0.0.0%26ipbits%3D0%26expire%3D1331626443%26sparams%3Did,itag,ip,ipbits,expire%26signature%3D53920C3CB55F8187B0A106633E4CAF018586ED89.29C7FDCF513E38DCAC0E204B680D926547A13177%26key%3Dck1&amp;iurl=http://video.google.com/ThumbnailServer2?app%3Dblogger%26contentid%3Dff14252fd6bcb5c4%26offsetms%3D5000%26itag%3Dw160%26sigh%3DRtH9VmLpPvmc_SPJaZCmMwXOKZs&amp;autoplay=0&amp;ps=blogger"allowFullScreen="true" /&gt;&lt;/object&gt;&lt;/div&gt;&lt;/div&gt;&lt;span style="font-size:85%;"&gt;[Miguel Moreno, 2003 (selección, edición-conversión a formato .wmv y presentación).
