pre-mRNA Processing

pre-mRNA Processing

In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor mRNA or pre-mRNA to distinguish it from mature mRNA.
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...

mRNA Stability and Gene Expression

mRNA Stability and Gene Expression

The structure and stability of mRNA molecules regulates gene expression, as mRNAs are a key step in the pathway from gene to protein. In eukaryotes, the half-life of mRNA varies from a few minutes up to several days. mRNA stability is essential in growth and development. The absence of the proteins regulating its stability, such as tristetraprolin in mice, can cause systemic issues, including bone marrow overgrowth, inflammation, and autoimmunity.

The Proteasome

The Proteasome

Eukaryotic cells can degrade proteins through several pathways. One of the most important amongst these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. A series of enzymes carry out the ubiquitination of the target proteins - E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...

Molecular Chaperones and Protein Folding

Molecular Chaperones and Protein Folding

The native conformation of a protein is formed by interactions between the side chains of its constituent amino acids. When the amino acids cannot form these interactions, the protein cannot fold by itself and needs chaperones. Notably, chaperones do not relay any additional information required for the folding of polypeptides; the native conformation of a protein is determined solely by its amino acid sequence. Chaperones catalyze protein folding without being a part of the folded protein.

Initiation of Translation

Initiation of Translation

Initiating translation is complex because it involves multiple molecules. Initiator tRNA, ribosomal subunits, and eukaryotic initiation factors (eIFs) are all required to assemble on the initiation codon of mRNA. This process consists of several steps that are mediated by different eIFs.
First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...

Nuclear Export of mRNA

Nuclear Export of mRNA

Before mRNAs are exported to the cytoplasm, it is crucial to check each mRNA for structural and functional integrity. Eukaryotic cells use several different mechanisms, collectively known as mRNA surveillance, to look for irregularities in mRNAs. Irregular or aberrant mRNA are rapidly degraded by various enzymes. If a defective mRNA escapes the surveillance, it would be translated into a protein which would either be non-functional or not function properly. One of the primary irregularities in...

Summary

A 1-year-old boy with profound sensorineural hearing loss received a cochlear implant. This case highlights cochlear implantation for severe hearing loss and developmental delay in infants.

Area of Science:

Pediatric Otolaryngology
Neuroscience
Ophthalmology

Background:

A 1-year-old boy presented with bilateral profound sensorineural hearing loss diagnosed neonatally.
Despite hearing aid use from 3 months, no behavioral responses were observed, indicating limited efficacy.
The child also exhibited mild developmental delays in motor milestones.

Observation:

Normal tympanic membranes and physical examination ruled out syndromic features.
Ophthalmological assessment revealed bilateral anesthetic corneas with abrasions, necessitating a tarsorrhaphy.
Auditory brainstem testing confirmed profound hearing loss with no responses in either ear.

Findings:

Magnetic Resonance Imaging (MRI) of the temporal lobe and brain, along with thin-section Computed Tomography (CT) of the temporal bones, were performed for cochlear implant assessment.

The patient underwent successful left cochlear implantation.

Implications:

Cochlear implantation is a viable option for infants with profound sensorineural hearing loss unresponsive to hearing aids.
This case underscores the importance of multidisciplinary assessment, including ophthalmology, for complex pediatric cases.
Early intervention with cochlear implants can potentially improve auditory outcomes and support developmental progress in affected children.
