The plastid-encoded RNA polymerase (PEP) plays an essential role in the transcription of the chloroplast genome. Here, we present a strategy to purify the transcriptionally active protein complex from transplastomic tobacco (Nicotiana tabacum) lines in which one of the PEP core subunits is fused to an epitope tag. We describe experimental procedures for designing transformation constructs for PEP purification, selection, and analysis of transplastomic tobacco plants.

Mechanistic target of rapamycin complex 1 (mTorC1) activity plays a crucial role in brain development. Here, we present an approach for rapamycin microinjection into the habenula of larval zebrafish to achieve localized inhibition of the mTorC1 pathway and explore the role of mTorC1 in habenula function. We describe steps for performing microinjections and maintaining zebrafish larvae before and after the procedure.

Laboratory of Renal Toxicopathology & Medicine, P.G. Department of Environmental Sciences, Sambalpur University, Burla, Odisha, 768019, India.
Background: The present community-based study assessed the prevalence of chronic kidney disease (CKD)/chronic kidney disease of unknown origin (CKDu) as well as anemia in some intense agricultural zones under Hirakud Command Area and evaluated their association with pesticides and heavy metal exposure.
Methods: Random cluster sampling method was used to assess the prevalence of CKD and anemia. Hematological analysis was carried out using autoanalyzer.

Hair follicle (HF) development and pigmentation are complex processes governed by various signaling pathways, such as TGF-β and FGF signaling pathways. Nestin + (neural crest like) stem cells are also expressed in HF stem cells, particularly in the bulge and dermal papilla region. However, the specific role and differentiation potential of these Nestin-positive cells within the HF remain unclear, especially regarding their contribution to melanocyte formation and hair pigmentation.

MicroRNAs (miRNAs) and transfer RNA-derived stress-induced RNAs (tiRNAs) have emerged as crucial players in the post-transcriptional regulation of gene expression in various cellular processes, including immunity and host defense against infections. In recent years, increasing evidence has highlighted their complex role in influencing the host response during viral and bacterial infections. miRNAs have been shown to play multiple roles in host-pathogen interaction like TLR activation and altered disease virulence during bacterial infections.
