The elucidation of the entire complement of genes encoding protein tyrosine phosphatases (PTPs) in human genome, the human 'PTPome', has made it possible to experimentally address the entire family in an unbiased manner. Here we describe a functional RNA interference-based assay, in which we evaluate 87 of the known 107 PTPs for effects on cell survival in a high throughput manner. The details of assay rationale and design, instrumentation, pitfalls, data analysis, and further validation steps are described. We also discuss the suitability of this technology for further assay development and application to other functional read-outs and signaling pathways.

Background: Rex rabbit is famous for its silky and soft fur coat, a characteristic predominantly attributed to its hair follicles. Numerous studies have confirmed the crucial roles of mRNAs and non-coding RNAs (ncRNAs) in regulating key cellular processes such as cell proliferation, differentiation, apoptosis and immunity. However, their involvement in the regulation of the hair cycle in Rex rabbits remains unknown.

Mares with endometrosis exhibit histological changes not only in the endometrium but also in the myometrium that suggest possible functional impairment. The molecular background of these changes is not well understood. We hypothesize that the transcriptomic profile of the mare myometrium varies depending on the degree of endometrosis in mares.

The 40S ribosomal subunit recycling pathway is an integral link in the cellular quality control network, occurring after translational errors have been corrected by the ribosome-associated quality control (RQC) machinery. Despite our understanding of its role, the impact of translation quality control on cellular metabolism remains poorly understood. Here, we reveal a conserved role of the 40S ribosomal subunit recycling (USP10-G3BP1) complex in regulating mitochondrial dynamics and function.

Background: Accurate quantification of microRNA (miRNA) is of great significance because it provides opportunities for the accurate early diagnosis of a series of human diseases including cancers. Currently, complicated nucleic acid amplification technologies are always required for the highly sensitive miRNA detection. The introduction of nucleic acid signal amplification coupled with various enzymes will inevitably lead to tedious work and increase the complexity of the analysis process.
