Roles of cell volume in molecular and cellular biology

Extracellular tonicity and volume regulation control a great number of molecular and cellular functions including: cell proliferation, apoptosis, migration, hormone and neuromediator release, gene expression, ion channel and transporter activity and metabolism. The aim of this review is to describe these effects and to determine if they are direct or are secondarily the result of the activity of second messengers.     

Supporting taxonomic names in cell and molecular biology databases

Groups of organisms require labels or names to refer to them; however, the idea of a single static name index, although tempting for its simplicity, is both impractical and unadvisable as a basis for referring to organisms for which data has been collected and stored for analyses and sharing. The relevant issues are described and some of the challenges facing database researchers are discussed.     

植物原生质体在分子细胞生物学研究中的应用

植物原生质体是去除了细胞壁的裸露细胞,其具有细胞全能性,现广泛应用于植物分子细胞生物学的研究中,可以大大缩减实验周期,并有助于得到体内实验的实时检测数据。该文除了介绍植物原生质体的提取和纯化方法外,还对国内外利用各种植物的原生质体进行细胞瞬时转化、亚细胞定位、细胞融合和大分子复合物相互作用等试验进行了总结和讨论。植物原生质体还可用于基因表达模式的实时检测,并作为生物反应器的受体细胞进行代谢物的体外生产。此外,还对当前该技术所面临的瓶颈进行了分析,为植物原生质体在分子细胞生物学领域的应用提供帮助,为技术的优化和推广提供参考。     

Towards the molecular biology of cell adhesion in Drosophila

The characterization of extracellular matrix molecules and their putative receptors is rapidly evolving in Drosophila. Where corresponding vertebrate and Drosophila extracellular proteins have been identified they are very similar with respect to their structural properties, suggesting a high degree of conservation during evolution. By contrast, indications for components homologous to vertebrate cell-cell adhesion molecules are still very sparse. Studies on the regulation of the Drosophila genes encoding cell adhesion molecules that are involved in general basic functions during morphogenesis, together with a knowledge of the function of the genes responsible for pattern formation, should lead towards a more complete understanding of the organism's developmental program.     

Role of molecular cell biology in understanding disease.

Molecular techniques have revolutionised our knowledge of cell and tissue function in both health and disease. We already have new and powerful treatments based on an understanding of communication between cells by messenger molecules called cytokines. Furthermore, there is great therapeutic promise in defining molecules which regulate cell adhesion, motility, proliferation, survival, and death. Rational manipulation of cell and tissue function for therapeutic ends may be much closer than you think.     

Firefly luciferase as a tool in molecular and cell biology

The unique properties of firefly luciferase and the cloning of the gene for this enzyme have spawned a number of novel applications of this protein. We summarize a few of these applications including its use as a reporter gene, as a model for the study of protein import into peroxisomes, and as a component of a heterologous gene expression system.     

Recent developments in the cell and molecular biology of root hairs

Recent results in root hair research show that these tip-growing cells are useful models in plant cell biology research. The review covers a range of topics, but there is particular emphasis on the use of mutants in molecular (genetic) analysis.     

A decade of molecular cell biology: achievements and challenges

Nature Reviews Molecular Cell Biology celebrated its 10-year anniversary during this past year with a series of specially commissioned articles. To complement this, here we have asked researchers from across the field for their insights into how molecular cell biology research has evolved during this past decade, the key concepts that have emerged and the most promising interfaces that have developed. Their comments highlight the broad impact that particular advances have had, some of the basic understanding that we still require, and the collaborative approaches that will be essential for driving the field forward.
