Expression of the DeaD RNA Helicase Is Regulated at Multiple Levels through Its Long mRNA 5' Untranslated Region.

DEAD-box proteins (DBPs) are a prominent class of RNA remodeling proteins that alter RNA structure, a process they typically perform through an ATP-dependent RNA helicase activity. Although many DBPs have been characterized at the structural and functional level in detail, much less is known about how they are regulated. We previously showed that the mRNA for the Escherichia coli DeaD DBP contains an unusually long 5' untranslated region (5' UTR) of 838 nucleotides (nt) and that it is the primary RNA determinant of DeaD autoregulation.

Early rRNA processing is a stress-dependent regulatory event whose inhibition maintains nucleolar integrity.

The production of ribosomes is an energy-intensive process owing to the intricacy of these massive macromolecular machines. Each human ribosome contains 80 ribosomal proteins and four non-coding RNAs. Accurate assembly requires precise regulation of protein and RNA subunits.

Actionable Cytopathogenic Host Responses of Human Alveolar Type 2 Cells to SARS-CoV-2.

Human transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causative pathogen of the COVID-19 pandemic, exerts a massive health and socioeconomic crisis. The virus infects alveolar epithelial type 2 cells (AT2s), leading to lung injury and impaired gas exchange, but the mechanisms driving infection and pathology are unclear. We performed a quantitative phosphoproteomic survey of induced pluripotent stem cell-derived AT2s (iAT2s) infected with SARS-CoV-2 at air-liquid interface (ALI).

snoRNPs: Functions in Ribosome Biogenesis.

Ribosomes are perhaps the most critical macromolecular machine as they are tasked with carrying out protein synthesis in cells. They are incredibly complex structures composed of protein components and heavily chemically modified RNAs. The task of assembling mature ribosomes from their component parts consumes a massive amount of energy and requires greater than 200 assembly factors.

Dual-level autoregulation of the DeaD RNA helicase via mRNA stability and Rho-dependent transcription termination.

DEAD-box proteins (DBPs) are RNA remodeling factors associated with RNA helicase activity that are found in nearly all organisms. Despite extensive studies on the mechanisms used by DBPs to regulate RNA function, very little is known about how DBPs themselves are regulated. In this work, we have analyzed the expression and regulation of DeaD/CsdA, the largest of the DBPs in ().

eIF4G has intrinsic G-quadruplex binding activity that is required for tiRNA function.

As cells encounter adverse environmental conditions, such as hypoxia, oxidative stress or nutrient deprivation, they trigger stress response pathways to protect themselves until transient stresses have passed. Inhibition of translation is a key component of such cellular stress responses and mounting evidence has revealed the importance of a class of tRNA-derived small RNAs called tiRNAs in this process. The most potent of these small RNAs are those with the capability of assembling into tetrameric G-quadruplex (G4) structures.

Adenocarcinoma in a tailgut cyst: A rare case report.

Tailgut cysts (TGCs) are rare congenital lesions derived from the remnants of primitive hindgut and are usually lined by squamous, transitional, or glandular epithelium. Malignant transformation in TGC may occur which is still rarer. Most common malignancies that arise from these cysts are adenocarcinomas.

Transforming the attitudes of young men about gender roles and the acceptability of violence against women, Bihar.

Although the importance of working with young men to transform traditional gender norms has been widely acknowledged, programmes for young men remain sparse in highly gender stratified settings such as India, and those that have been implemented have not reached those in rural areas and those out-of-school. Drawing on data from a cluster randomised controlled trial with panel surveys, of a gender-transformative life skills education and sports-coaching programme conducted among young men aged 13-21 who were members of youth clubs, this paper examines the extent to which it transformed the gender role attitudes of young men and instilled in them attitudes rejecting violence against women and girls. The intervention succeeded in changing gender role attitudes and notions of masculinity, attitudes about men's controlling behaviours over women/girls, attitudes about men's perpetration of violence on a woman/girl and perceptions about peer reactions to young men acting in gender-equitable ways.

Role of Field Staining in the Cytological Assessment of Intraoperative Surgical Specimens.

Objective: To study the role of Field staining in scrape smears for intraoperative cytological (IOC) diagnosis. Specimens were assessed for categorizing among benign and malignant lesions, lymph node status, and adequacy of surgical cut margins as per specimen. Technique, adequacy, and quality were assessed along with comparison of cytological diagnosis with final histopathological diagnosis obtained on routine hematoxylin and eosin-stained slides.

Role of fine needle aspiration cytology in diagnosis of brown tumor secondary to parathyroid adenoma.

Brown tumor (BT) is caused by altered metabolism of calcium resulting from hyperparathyroidism (primary or secondary). The most common cause of hyperparathyroidism is isolated parathyroid adenoma (PA), and the most common symptoms are hypercalcemia related. BT is considered as a late manifestation of PA and usually diagnosed after surgical treatment of the bony lesion.

Cytomorphological Findings of Follicular Dendritic Cell Sarcoma on Fine-Needle Aspiration Cytology.

Background: Follicular dendritic cell sarcoma (FDCS) is a rare neoplasm arising from follicular dendritic cells of germinal centers. The most common site of origin is lymph nodes and it may mimic a variety of tumors at that location, including carcinomas and sarcomas. Diagnosis is frequently missed on cytology as there are very few case reports describing the cytological characteristics of the lesion.

Leiomyosarcoma of Renal Vein - A Rare Case Report.

Leiomyosarcomas (LMS) arising from vascular channel are rare and more often arise from inferior vena cava and pulmonary arteries. Primary renal vein LMS are even rarer and occur predominantly in females with peak in fifth and sixth decade. Preoperative diagnosis is difficult because these are rare tumours and present with symptoms and radiological findings similar to Renal Cell Carcinoma (RCC).

A host factor supports retrotransposition of the TRE5-A population in Dictyostelium cells by suppressing an Argonaute protein.

Background: In the compact and haploid genome of Dictyostelium discoideum control of transposon activity is of particular importance to maintain viability. The non-long terminal repeat retrotransposon TRE5-A amplifies continuously in D. discoideum cells even though it produces considerable amounts of minus-strand (antisense) RNA in the presence of an active RNA interference machinery.

Post-transcriptional regulation of ribosomal protein genes during serum starvation in Entamoeba histolytica.

Ribosome synthesis involves all three RNA polymerases which are co-ordinately regulated to produce equimolar amounts of rRNAs and ribosomal proteins (RPs). Unlike model organisms where transcription of rRNA and RP genes slows down during stress, in E. histolytica rDNA transcription continues but pre-rRNA processing slows down and unprocessed pre-rRNA accumulates during serum starvation.

Diagnosis of histoplasmosis on lymph node fine needle aspiration cytology utilizing Giemsa stain: a report of three cases.

Background: Histoplasmosis is a fungal infection caused by Histoplasma capsulatum; it mostly occurs in immunocompromised individuals. Disseminated histoplasmosis may affect almost all systems. The lymph node is frequently involved in the reticuloendothelial dissemination.

Amyloid goiter: cytomorphological features and differential diagnosis on fine needle aspiration cytology: a case report.

Background: Amyloid goiter is a rare cause of thyroid enlargement which can be confused clinically as well as cytologically with both colloid goiter and neoplastic process of thyroid.

Case: A 30-year-old man, diagnosed with chronic kidney disease 5 months previously and currently on dialysis and awaiting renal transplant, was referred by clinicians for fine needle aspiration cytology (FNAC) for thyroid swelling. FNAC showed dense amorphous clumps of extracellular material which appeared magenta colored on Giemsa and eosinophilic on Papanicolaou stain.

Ribosomal RNA and protein transcripts persist in the cysts of Entamoeba invadens.

In most organisms rDNA transcription ceases under conditions of growth stress. However, we have earlier shown that pre-rRNA accumulates during encystation in Entamoeba invadens. We labeled newly-synthesized rRNA during encystation, with [methyl-(3)H] methionine in the presence of chitinase to enable uptake of isotope.

The role of squash cytology in rapid on-site adequacy checking and rapid diagnosis in image-guided gun biopsy at a tertiary cancer center.

Objective: To evaluate the role of squash cytology in rapid on-site adequacy checking (ROSAC) of image-guided gun biopsy and to determine its diagnostic accuracy at a tertiary cancer center.

Study Design: This was a prospective study on 183 patients undergoing image-guided biopsy. Squash smears were prepared from biopsy cores and checked for adequacy by cytotechnologists.

The ribosomal RNA transcription unit of Entamoeba invadens: accumulation of unprocessed pre-rRNA and a long non coding RNA during encystation.

The ribosomal RNA genes in Entamoeba spp. are located on extrachromosomal circular molecules. Unlike model organisms where rRNA transcription stops during growth stress, Entamoeba histolytica continues transcription; but unprocessed pre-rRNA accumulates during stress, along with a novel class of circular transcripts from the 5'-external transcribed spacer (ETS).
