For a long time, noncoding RNAs (ncRNAs) were considered irrelevant fragments of the genome, dismissed as genetic noise. However, recent breakthroughs have unveiled their crucial Role in regulating gene expression, influencing fundamental biological processes such as chromatin remodeling, epigenetic modifications, and cellular communication. Among them, long noncoding RNAs (lncRNAs) and microRNAs (miRNAs) have drawn considerable attention due to their strong association with neurodegenerative disorders and cardiovascular diseases (CVDs). Despite their apparent differences, these conditions share molecular regulatory networks that ncRNAs help orchestrate. LncRNAs, like ANRIL and MEG3, play a Role in vascular integrity and cardiac fibrosis, while MIAT and MALAT1 are implicated in heart failure and ischemic injury. In Alzheimer's disease, BACE1-AS and BC200 contribute to the buildup of amyloid plaques and tau protein tangles, worsening cognitive decline. The ability of ncRNAs to act as molecular sponges-binding to miRNAs and modulating gene expression-demonstrates their intricate Role in disease progression. With advances in sequencing technologies and computational biology, ncRNAs are emerging as promising biomarkers and therapeutic targets. New approaches, including CRISPR-based gene editing and RNA therapeutics, present exciting possibilities for intervention. However, challenges such as stability, precise delivery, and potential side effects must be addressed before these treatments can be translated into clinical practice. This chapter delves into the expanding field of ncRNA research, highlighting its potential to reshape the future of precision medicine and targeted therapies. Show less

Millions of people around the globe are affected by Alzheimer's disease (AD). This crippling condition has no treatment despite intensive studies. Some phytocompounds have been shown to protect against Alzheimer's in recent studies. Thus, this work aimed to examine Bacopa monnieri phytocompounds' synergistic effects on neurodegeneration, antioxidant activity, and cognition in the scopolamine-induced AD mice model. The toxicity study of two phytocompounds: quercetin and bacopaside X revealed an LD The neuroprotection experiment consists of 6 groups i.e., control (saline), scopolamine (1 mg/kg), donepezil (5 mg/kg), Q (25 mg/kg), BX (20 mg/kg), and Q + BX (25 mg/kg + 20 mg/kg). Visual behavioral assessment using the Morris water maze showed that animals in the diseased model group (scopolamine) moved more slowly toward the platform and exhibited greater thigmotaxis behavior than the treatment and control groups. Likewise, the concentration of biochemical NO, GSH, and MDA improved in treatment groups concerning the diseased group. mRNA levels of different marker genes including ChAT, IL-1α, IL-1 β, TNF α, tau, and β secretase (BACE1) improved in treatment groups with respect to the disease group. Both bacopaside X and quercetin synergistically have shown promising results in neuroprotection. Therefore, it is suggested that Q and BX may work synergistically due to their antioxidant and neuroprotective property. Show less
