RNA interference reveals the escape response mechanism of Paramecium to mechanical stimulation
In Paramecium, a mechanical stimulus applied to the posterior portion of the cell causes a transient increase in membrane permeability to potassium ions, transiently rendering the membrane in a hyperpolarized state.

Density-and trait-mediated effects of a parasite and a predator in a tri-trophic food web [PDF]
1. Despite growing interest in ecological consequences of parasitism in food webs, relatively little is known about effects of parasites on long-term population dynamics of non-host species or about whether such effects are density- or trait- mediated ...

Pdsg1 and Pdsg2, novel proteins involved in developmental genome remodelling in Paramecium. [PDF]
The epigenetic influence of maternal cells on the development of their progeny has long been studied in various eukaryotes. Multicellular organisms usually provide their zygotes not only with nutrients but also with functional elements required for ...

Using Paramecium as a Model for Ciliopathies [PDF]
Paramecium has served as a model organism for the studies of many aspects of genetics and cell biology: non-Mendelian inheritance, genome duplication, genome rearrangements, and exocytosis, to name a few. However, the large number and patterning of cilia that cover its surface have inspired extraordinary ultrastructural work.

Evolution of the Exon-Intron Structure in Ciliate Genomes. [PDF]
A typical eukaryotic gene is comprised of alternating stretches of regions, exons and introns, retained in and spliced out a mature mRNA, respectively.

Calmodulin in Paramecium: Focus on Genomic Data
Calcium (Ca2+) is a universal second messenger that plays a key role in cellular signaling. However, Ca2+ signals are transduced with the help of Ca2+-binding proteins, which serve as sensors, transducers, and elicitors. Among the collection of these Ca2+
