Over the past decade, high-throughput RNA sequencing (RNA-seq) has vastly expanded our understanding of transcriptome dynamics in human physiology and disease. As a powerful tool for investigating systematic changes in RNA biology, RNA-seq has facilitated the discovery of novel functional RNA species. Mature RNA transcripts, which transmit genetic information from DNA to proteins, undergo intricate transcriptional and post-transcriptional regulation. This process allows a single gene to produce multiple RNA transcripts, each performing specific functions depending on the physiological or pathological context. Specific RNA transcripts (SRTs) are uniquely expressed in particular tissues or tumors and are closely associated with tissue-specific functions or disease states, particularly cancer. This review explores the generation of SRTs through key mechanisms, such as alternative splicing (AS), transcriptional regulation, polyadenylation (polyA), and the influence of transposable elements (TEs). We also examine their critical roles in normal tissue development and diseases, with an emphasis on their relevance to cancer. Furthermore, the potential applications of SRTs in diagnosing and treating diseases, especially malignancies, are discussed. By serving as diagnostic markers and therapeutic targets, SRTs hold significant promise in the development of personalized medicine and precision therapies. This review aims to provide new insights into the importance of SRTs in advancing the understanding and treatment of human diseases.

Cystic fibrosis (CF) is an autosomal recessive inherited disease affecting multiple body systems.Pseudo-Bartter syndrome (PBS) is a common manifestation of CF, with such clinical features as hypochloremia, hyponatremia, hypokalemia and metabolic alkalosis.However, PBS patients do not have renal tubulopathy.Children with CF are prone to develop electrolyte abnormalities due to fluid and electrolyte loss.In this article, the pathogenesis, clinical manifestations, diagnosis, and treatment of CF associated PBS were reviewed in order to enhance clinical understan-ding of this disease.
