Transcription Elongation Factors

Transcription elongation is a dynamic process that alters depending upon the sequence heterogeneity of the DNA being transcribed. Hence, it is not surprising that the elongation complex's composition also varies along the way while transcribing a gene. The transcription elongation is regulated via pausing of RNA polymerase on several occasions during transcription. In bacteria, these halts are necessary because the transcription of DNA into mRNA is coupled to the translation of that mRNA into a...

The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...

Here we detail protocols specifically designed to monitor morphogenic defects that occur during early and late phases of embryonic elongation of the nematode Caenorhabditis elegans. Ultimately, these protocols are designed to identify genes that regulate these phases and to characterize their differential requirements along the antero-posterior axis of the embryo.

This report describes a method to induce chronic experimental autoimmune dry eye in Lewis rats through immunization with an emulsion of rat lacrimal gland extract, ovalbumin, and complete Freund's adjuvant, followed by the injection of lacrimal gland extract and ovalbumin into the forniceal subconjunctiva and lacrimal glands six weeks later.
FAQs
Standardization makes axial-length values more comparable across individuals, experimental conditions, and time points. Without a consistent measurement approach, observed differences could reflect variation in assessment rather than actual ocular growth. This consistency is especially important when researchers examine developmental changes, compare control and intervention conditions, or relate eye structure to visual performance.
Changes in axial length provide a structural indicator that can be evaluated alongside visual function. When measurements are collected at multiple time points, researchers can identify growth-related changes and examine whether they correspond with altered visual performance. This helps connect physical development of the eye with broader processes involved in sensory development.
These measurements give neuroscience studies an objective ocular outcome that complements analyses of neural visual processing. Researchers can relate retinal and ocular development to how visual information is processed, rather than considering neural function in isolation. The approach therefore supports investigations linking changes in eye structure with sensory development and vision-related outcomes.
A study first obtains a standardized estimate of axial length, then records the value for each participant, condition, or time point. Researchers compare those values to identify structural differences or growth-related changes. The resulting comparisons can then be examined alongside visual-function measures or other study outcomes to assess relationships between ocular development and vision.
Researchers can use the measure when investigating refractive development and myopia, because changes in ocular growth provide an objective structural outcome. Values may be compared across individuals, conditions, or time points to evaluate growth patterns. In intervention studies, the measurements can help determine whether an approach is associated with changes in eye growth.
Repeated standardized measurements allow researchers to compare axial-length values before and after, or between, relevant conditions. A difference in the measured values can indicate a change in ocular growth associated with the intervention, while accompanying visual-function data help place that structural result in context. This makes the measure useful for assessing developmental and vision-related outcomes.
