Research on Circular RNA Characteristics and Diseases

Circular RNAs are covalently closed RNA molecules produced mainly by back-splicing, in which a downstream splice donor joins an upstream acceptor. They were once treated largely as rare splicing by-products, but high-throughput RNA sequencing and dedicated computational methods revealed abundant, conserved, and tissue-specific circles in animals. Their closed structure lacks free 5-prime and 3-prime ends and often gives greater resistance to exonucleases than linear RNA. Current research examines circRNA biogenesis, localization, turnover, function, and disease association, with particular interest in their stability as biomarkers and their capacity to regulate gene expression[1][2][3].

Biogenesis depends on spliceosomal activity, intronic complementarity such as inverted Alu repeats, and RNA-binding proteins that bring splice sites together or oppose circularization. Exonic circRNAs commonly accumulate in the cytoplasm, whereas some intron-containing circles remain nuclear and influence transcription. Mechanisms include binding proteins, competing for selected microRNAs when sufficiently abundant and rich in binding sites, modulating parental-gene expression, organizing molecular complexes, and in some cases serving as templates for cap-independent translation. A circRNA's function cannot be inferred from circularity or predicted sites alone; investigators must quantify absolute abundance, distinguish the circle from its linear host transcript, demonstrate direct binding, and show a molecular consequence at endogenous concentration[1][2][3].

Disease studies report altered circRNA profiles in cancer, cardiovascular and neurological disorders, diabetes, and inflammatory conditions. Their stability and presence in blood or extracellular vesicles support diagnostic research, while tissue-specific circles may identify cell injury or tumor lineage. Functional studies use junction-targeting oligonucleotides or CRISPR-based disruption of circularization to test effects on proliferation, apoptosis, metastasis, synaptic function, or immune signaling. Engineered circRNAs are also being explored for durable protein production and RNA therapeutics because circularization can extend RNA persistence. However, most proposed clinical biomarkers remain in retrospective cohorts, and many disease-associated circles have not shown incremental value beyond established tests[1][3].

Major gaps arise from measurement and specificity. Reverse transcription can create template-switching artifacts, repetitive sequences complicate alignment, RNase R does not remove every linear RNA, and host-gene changes can mimic circRNA regulation. Rigorous validation should combine divergent-junction PCR, sequencing of the back-splice junction, resistance testing, northern blotting or orthogonal size analysis, and controls for linear transcripts. Perturbation should target the junction or flanking circularization elements and include rescue with a circle that preserves sequence but avoids the intervention. Long-read and single-cell methods can resolve isoforms and cellular origin, while standardized reporting can improve comparison across cohorts. Clinical translation requires prospective validation, reproducible preanalytics, and evidence that manipulating the circle is safe and mechanistically superior to targeting its associated protein or linear RNA pathway Biomarker studies should predefine the circular junction assay, normalization strategy, disease stage, and clinical comparator. Hemolysis, platelet activation, and sample storage can change extracellular RNA measurements and require controls. For therapeutic circles, innate immune sensing, translation fidelity, tissue delivery, and product heterogeneity need direct evaluation. These criteria separate a biologically interesting RNA from a clinically reliable diagnostic or drug platform. Independent cohorts should confirm both analytical stability and decision-relevant clinical performance[1][2][3].

HY-L251 Ionizable Lipid Compound Library
Ionizable lipids are a class of specialized, functional lipid molecules with pH-sensitive charge characteristics. They are primarily divided into two major categories: ionizable cationic lipids and ionizable anionic lipids, though the term typically specifies ionizable cationic lipids within the biomedical field. Structurally, these lipids consist of an ionizable hydrophilic headgroup, a biodegradable linker, and hydrophobic tails. Their primary application is serving as the key delivery vehicle in lipid nanoparticles (LNPs) to encapsulate negatively charged nucleic acid macromolecules, such as mRNA vaccines, siRNA therapeutics, and CRISPR gene-editing components. In a physiological, neutral environment, they remain electrically neutral to minimize systemic toxicity and prolong circulation time. Upon entering the acidic microenvironment of cellular endosomes, however, they undergo protonation to become positively charged, thereby inducing membrane fusion and enabling the highly efficient intracellular release of the nucleic acid cargo. Consequently, they serve as the technological cornerstone for bringing nucleic acid therapies into clinical application. To accelerate the translational process of cutting-edge nucleic acid drugs, MCE has meticulously constructed an ionizable lipid compound library containing 93 high-performance molecules, aiming to provide researchers and pharmaceutical professionals with a high-throughput, multi-dimensional lipid screening platform.

HY-P5415 DABCYL-GABA-Ser-Gln-Asn-Tyr-Pro-Ile-Val-Gln-EDANS
DABCYL-GABA-Ser-Gln-Asn-Tyr-Pro-Ile-Val-Gln-EDANS is a biological active peptide. (DABCYL-GABA-Ser-Gln-Asn-Tyr-Pro-Ile-Val-Gln-EDANS is also called HIV protease substrate I in some literature. It is widely used for the continuous assay for HIV protease activity. The 11-Kd protease (PR) encoded by the human immunodeficiency virus 1 (HIV-1) is essential for the correct processing of viral polyproteins and the maturation of infectious virus, and is therefore a target for the design of selective acquired immunodeficiency syndrome (AIDS) therapeutics. The FRET-based fluorogenic substrate is derived from a natural processing site for HIV-1 PR. Incubation of recombinant HIV-1 PR with the fluorogenic substrate resulted in specific cleavage at the Tyr-Pro bond and a time-dependent increase in fluorescence intensity that is linearly related to the extent of substrate hydrolysis. The fluorescence quantum yields of the HIV-1 PR substrate in the FRET assay increased by 40.0- and 34.4-fold, respectively, per mole of substrate cleaved. Because of its simplicity and precision in the determination of reaction rates required for kinetic analysis, this substrate offers many advantages over the commonly used HPLC or electrophoresis-based assays for peptide substrate hydrolysis by retroviral PRs. Abs/Em = 340nm/490nm.)
