Hundreds of tRNA genes and pseudogenes are encoded by the human genome. tRNAs are the second most abundant type of RNA in the cell. Advancement in deep-sequencing technologies have revealed the presence of abundant expression of functional tRNA-derived RNA fragments (tRFs). They are either generated from precursor (pre-)tRNA or mature tRNA. They have been found to play crucial regulatory roles during different pathological conditions. Herein, we briefly summarize the discovery and recent advances in deciphering the regulatory role played by tRFs in the pathophysiology of different human diseases.

Edible seeds play a significant role in contributing essential nutritional needs and impart several health benefits to improve the quality of human life. Previous literature evidence has confirmed that edible seed proteins, their enzymatic hydrolysates, and bioactive peptides (BAPs) have proven and potential attributes to ameliorate numerous chronic disorders through the modulation of activities of several molecular markers. Edible seed-derived proteins and peptides have gained much interest from researchers worldwide as ingredients to formulate therapeutic functional foods and nutraceuticals. In this review, four main methods are discussed (enzymatic hydrolysis, gastrointestinal digestion, fermentation, and genetic engineering) that are used for the production of BAPs, including their purification and characterization. This article’s main aim is to provide current knowledge regarding several health-promoting properties of edible seed BAPs in terms of antihypertensive, anti-cancer, antioxidative, anti-inflammatory, and hypoglycemic activities.

Dengue is potentially a life-threatening arthropod-borne viral infection for which there are no known therapeutic agents till date. Early stage diagnosis of dengue infection is still lacking. Diagnosis is only made after severe manifestations and later stages of infection. Timely prognosis can prevent dengue related mortalities. The nucleic acid-based therapy has potential to emerge as a promising approach for early diagnosis and treatment of this viral infection. Many studies have been carried out suggested the regulatory role of ncRNAs thereby revealing the importance of protein-RNA and RNA-RNA interactions during infection. Various regulatory RNAs are either expressed by mammalian cells or generated by viral RNA have reported to play important roles in viral life cycle including dengue virus. Thus exploring host-virus interaction will pave the novel path for understanding the pathophysiology of febrile infection in dengue. Rapid advances in sequencing techniques along with significant developments in the field of RNA studies has made RNA therapeutics as one of the promising approaches as antiviral targets. The idea of RNA based therapies has been greatly backed by a Hepatitis C virus drug, Miravirsen which has successfully completed phase II clinical trial. In the present review, we will discuss the implications of different non-coding RNAs in dengue infection. Differential expression of small ncRNA may serve as a reliable biomarker of disease severity during different stages of infection and can also play regulatory roles in disease progression.
