Unfortunately, in most cases the technology to be transferred to learning students is complex and requires multi-step approaches. In this respect, simple and straightforward experimental protocols might be of great interest. This study was aimed at presenting a laboratory exercise focusing (a) on a very challenging therapeutic strategy, i.e. microRNA therapeutics, and (b) on the employment of biomolecules of great interest in applied biology and pharmacology, i.e. peptide nucleic acids (PNAs). The aims of the practical laboratory were to determine: (a) the possible PNA-mediated arrest in RT-qPCR, to be eventually used to demonstrate PNA targeting of selected miRNAs; (b) the possible lack of activity on mutated PNA sequences; (c) the effects (if any) on the amplification of other unrelated miRNA sequences. The results which can be obtained support the following conclusions: PNA-mediated arrest in RT-qPCR can be analyzed in a easy way; mutated PNA sequences are completely inactive; the effects of the employed PNAs are specific and no inhibitory effect occurs on other unrelated miRNA sequences. This activity is simple (cell culture, RNA extraction, RT-qPCR are all well-established technologies), fast (starting from isolated and characterized RNA, few hours are just necessary), highly reproducible (therefore easily employed by even untrained students). On the other hand, these laboratory lessons require some facilities, the most critical being the availability of instruments for PCR. While this might be a problem in the case these instruments are not available, we would like to underline that determination of the presence or of a lack of amplified product can be also acquired using standard analytical methods based on agarose gel electrophoresis.

Accordingly, practical laboratory classrooms based on teaching molecular pharmacology methods employed in the development of therapeutic strategies are of great interest for Etofenamate students of courses in Biotechnology, Applied Biology, Pharmaceutic and Technology Chemistry, Translational Oncology. Regrettably, despite several experiences are important, they are challenging as, in most of the cases, the technology to be transferred to learning students is complex and requires multi-step methods [3]. Furthermore, several technologies require complex instrumentation(s) and costly reagents and materials [3]. Finally, several techniques are hard to be followed in in actual lab (wet-lab) setting in the case of large class size resulting in student crowding [4]. Based on these considerations virtual laboratories have been proposed, which facilitate learning of technologies requiring complex devices, costly reagents and materials, highly trained staff [2, 5C8]. However, we should underline that this students expectation might require also the organization of wet-labs for acquiring complex skills and the ability to discuss challenging biomedical methods [9,10]. In this respect, simple and straightforward experimental protocols might be useful and of great interest, especially in the era of personalized medicine and molecular targeting. This study is aimed at presenting a laboratory exercise focusing (a) on a very challenging therapeutic strategy, i.e. microRNA therapeutics [11C14], and (b) around the employment of biomolecules of great desire for applied biology and pharmacology, i.e. Peptide Nucleic Acids (PNAs) [15C17]. MicroRNAs (miRNAs) are a family of evolutionary conserved small (19 to 25 nucleotides in length) noncoding RNAs playing important functions in the post-transcriptional control of gene expression, operated at the level of mRNA translation and based on the miRNA-dependent acknowledgement of 3UTR, CDS and 5UTR mRNA sequences [18C22]. Excellent reviews on miRNA biology are available and might be considered in the teaching materials available to the students [23,24]. A second point is usually that microRNAs are novel and very important targets for therapeutic strategies [13,14, 25C28]; the anti-miRNA and miRNA replacement approaches to change miRNA-regulated gene expression are summarized in Physique A in S1 File).

The aims of the practical laboratory were to determine: (a) the possible PNA-mediated arrest in RT-qPCR, to be eventually used to demonstrate PNA targeting of chosen miRNAs; (b) having less activity on mutated PNA sequences; (c) the consequences (if any) in the amplification of various other unrelated miRNA sequences. The outcomes which may be attained support the next conclusions: PNA-mediated arrest in RT-qPCR could be analyzed within a easy method; mutated PNA sequences are totally inactive; the consequences from the utilized PNAs are particular no inhibitory result occurs on various other unrelated miRNA sequences. This activity is easy (cell lifestyle, RNA removal, RT-qPCR are well-established technology), fast (beginning with isolated and characterized RNA, few hours are simply necessary), extremely reproducible (as a result easily utilized by also untrained learners). Alternatively, these lab lessons need some services, the most significant being the option of musical instruments for PCR. While this may be a issue in the event these musical instruments are not obtainable, we wish to underline that perseverance from the existence or of too little amplified product could be also attained using regular analytical techniques predicated on agarose gel electrophoresis.

Exceptional review articles on miRNA biology can be found and might be looked at in the teaching components open to the college students [23,24]. Another point can be that microRNAs are book and very essential targets for restorative strategies [13,14, 25C28]; the anti-miRNA and.On the other hand, U251 cell culture and RNA extraction/characterization (a) or just RNA extraction (b) may be considered. generally the technology to become used in learning college students is complicated and requires multi-step techniques.
