On this interview, business professional Dr. Lohit Khera discusses the evolving position of microRNA in analysis, diagnostics, and precision drugs. He additionally highlights the newest RNA extraction and evaluation improvements and the way these superior applied sciences deal with key challenges in small RNA analysis.
What initially sparked the scientific curiosity in microRNA, and the way has that focus advanced over the previous decade?
The invention that microRNAs (miRNAs) regulate gene expression post-transcriptionally was a paradigm shift, and their position in developmental biology and most cancers caught researchers’ consideration globally.
Over the past decade, the sector has exploded with biomarker discovery from liquid biopsy samples, diagnostics, and even therapeutics, the place researchers are designing miRNA mimics and inhibitors. It’s changing into a translational science, with sturdy business and medical ties.
What makes microRNA such a strong goal in present organic and biomedical analysis?
MicroRNAs have a uncommon leverage as a result of they act like molecular switches that fine-tune complete gene networks; they could or won’t be particular to single genes. They’re additionally secure in biofluids, making them ideally suited candidates for non-invasive diagnostics from liquid biopsy samples. Their tissue- and disease-specific expression patterns present specificity, and optimized miRNA extraction kits deliver ease of use and sensitivity, which is exactly what researchers need of their biomarker or therapeutic targets.
Why is the flexibility to isolate all sizes of RNA—particularly microRNA—so important for researchers right now?
Small RNAs are notoriously tough to seize with conventional kits that favor longer transcripts, however their practical significance is large. Many labs would possibly miss out on important knowledge as a result of their extraction strategies will not be optimized for “actual” complete RNA restoration. Whether or not for focused microRNA expression profiling or performing sequencing, you want high-quality microRNA in applicable concentrations. This ensures reproducibility and accuracy, particularly when working with low-input like biofluids or degraded samples like FFPE tissue.
What are the most important challenges researchers face when working with small RNA, and the way are these being addressed by rising applied sciences?
Low abundance and contaminating background noise are persistent hurdles. Small RNAs are sometimes misplaced throughout extraction because of low abundance and the widespread extraction applied sciences affected by inherent bias towards giant nucleic acids. Though higher binding chemistries and ultra-low enter kits promise higher extraction, they should depend upon both utilizing giant service RNA or sturdy chemical compounds that may finally make their method into the ultimate eluted RNA and intrude with downstream purposes. Silicon carbide is a revolutionary resin that may seize small RNA with out the necessity for service RNA or undesirable chemical compounds.
Background noise is one other prevalent situation that’s extra regarding for NGS-based downstream purposes. This background noise makes use of up essential reagents throughout small RNA sequencing and impacts the genome-mapped reads and miRNA mapping. Norgen has not too long ago launched the EXTRAClean package, which eliminates this situation, considerably enhancing the output from small RNA sequencing.
Are you able to share the story behind Norgen Biotek Corp.’s founding and the issue it initially got down to remedy in RNA analysis?
Norgen Biotek was based by Dr. Yosef Haj-Ahmad, a scientist with a mission to develop and manufacture revolutionary nucleic acid (NA) purification kits, particularly from advanced samples like serum or FFPE tissue. The core situation was yield and integrity for small NAs like exosomal RNA and cell-free DNA (cfDNA). We needed to develop a platform that delivered constant, high-quality small RNAs throughout all fragment sizes all the way down to 20-25-nucleotide-long miRNAs. Our silicon carbide-based know-how was born out of that want. It’s now utilized by researchers who can not afford to lose sign because of partial restoration.

Norgen has developed its distinctive silicon carbide-based know-how for RNA isolation. How does this strategy evaluate to extra conventional silica-based strategies?
Silicon carbide has a broader binding profile than silica, significantly for low molecular weight nucleic acids. This implies we will retain lengthy and small RNAs and RNA with high and low GC content material with excessive effectivity. Conventional silica columns are likely to favor longer and high-GC-content transcripts and should underrepresent microRNAs or fragmented RNAs. Our strategy provides higher consistency, significantly for advanced or low-input samples.

What are among the most promising purposes of microRNA in fields like oncology, agriculture, or diagnostics?
In oncology, circulating microRNAs are reworking how we detect and monitor cancers. They provide real-time snapshots of tumor burden and therapy response.
In agriculture, plant microRNAs are being explored to enhance crop resilience and illness resistance. Diagnostic purposes like salivary microRNAs for oral cancers or urinary microRNAs for kidney illness are additionally booming.
How is microRNA used to drive innovation in non-invasive or minimally invasive diagnostics?
MicroRNAs are perfect for liquid biopsies—they are often remoted from plasma (blood), urine, and saliva, and their expression patterns change with illness state. This makes them good for early detection and monitoring without having tissue biopsies. We’re seeing diagnostic panels emerge for cancers, cardiovascular situations, and even neurodegenerative ailments. Some corporations are even combining microRNA profiles with machine studying to boost predictive energy. It’s a leap towards accessible, non-invasive diagnostics that can be utilized in routine screening.
As demand grows for precision drugs, how do you see RNA—particularly small RNA—shaping the way forward for customized therapy?
Small RNAs have gotten the molecular fingerprints of illness. Their skill to replicate dynamic physiological states makes them extremely helpful for tailoring remedies. For instance, microRNA signatures can assist stratify sufferers and predict therapeutic response in most cancers. As we combine multi-omics into precision drugs, microRNA profiling provides a complementary layer that bridges gene expression with medical phenotype. I believe within the close to future, we are going to see increasingly more inclusion of microRNA-informed therapeutic choices.
The final two Nobel Prizes in physiology have spotlighted RNA-based discoveries—what does that say about the way forward for this subject?
It underscores RNA’s central position in biology and drugs. From figuring out miRNA a few years in the past to the latest impression of modified mRNA for the COVID-19 vaccine, the Nobel wins replicate many years of foundational work lastly bearing fruit. This validation helps to extend funding, innovation, and public curiosity. RNA is now not only a messenger, it’s a software, a therapeutic, and a diagnostic molecule. The way forward for biomedicine may have RNA on the centre.
How do you envision the position of automation and AI in the way forward for RNA extraction and evaluation?
Automation is vital to consistency, particularly as labs scale up testing or function in regulated environments. We’re seeing extra demand for pre-filled, automation-ready kits and scalable protocols for various volumes of liquid biopsy samples. In the meantime, AI is reworking knowledge interpretation from microRNA-based diagnostics, the place expression patterns might be delicate. Machine studying algorithms can detect clinically related patterns involving many various miRNAs which are simple to overlook with conventional strategies. Collectively, automation and AI speed up discovery whereas minimizing human error, making RNA workflows extra environment friendly and reproducible.
