Summary
Chromatin structure in mouse kidney macula densa cells becomes less complex after birth. This age-related decrease in chromatin complexity occurs independently of texture, suggesting intrinsic nuclear factors play a role in development.
Area of Science:
- Developmental Biology
- Cell Biology
- Genomics
Background:
- Postnatal development involves significant cellular and tissue remodeling.
- Chromatin structure plays a crucial role in regulating gene expression during development.
Purpose of the Study:
- To investigate changes in chromatin structural complexity within kidney macula densa cells (MDC) during mouse postnatal development.
Main Methods:
- Kidney tissue from Swiss albino mice at four age points (0, 10, 20, 30 days) was analyzed.
- Fractal dimension, lacunarity, and Grey Level Co-occurrence Matrix (GLCM) texture parameters were used to quantify MDC nuclear chromatin complexity.
Main Results:
- A significant decrease in chromatin fractal dimension was observed in MDC from 10, 20, and 30-day-old mice compared to newborns.
- This reduction in chromatin complexity was consistent across age groups and independent of texture parameters.
Conclusions:
- Chromatin structural complexity in MDC decreases during postnatal development.
- Age-related intrinsic nuclear factors, not chromatin texture, appear to influence this developmental process.

03:17Inheritance of Chromatin Structures
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying DNA...
01:01Euchromatin
The extent of chromatin compaction can be studied by staining chromatin using specific DNA binding dyes. Under the microscope, the dense-compacted regions take up more dye, appearing darker, while the less-compact areas take up less dye and appear lighter. Based on the compaction level, chromatins are classified into two primary forms – euchromatin and heterochromatin.
Euchromatin is the less dense region of the chromatin and stains lighter. Euchromatin contains histone H3 extensively...

02:38Heterochromatin
The extent of chromatin compaction can be studied by staining chromatin using specific DNA binding dyes. Under the microscope, the dense-compacted regions that take up more dye are called heterochromatin. Heterochromatin is further classified into two forms – constitutive heterochromatin and facultative heterochromatin.
Constitutive heterochromatin: It is a highly compact region of chromatin that is mostly concentrated in the centromere and telomere. Unlike euchromatin, the amino acid at 9th...

01:32Chromatin Modification in iPS Cells
Chromatin modification alters gene expression; therefore, scientists can add histone-modifying enzymes, histone variants, and chromatin remodeling complexes to somatic cells to aid reprogramming into pluripotent stem (iPS) cells.
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...

02:04Polytene Chromosomes
Polytene chromosomes are giant interphase chromosomes with several DNA strands placed side by side. They were discovered in the year 1881 by Balbiani in salivary glands, intestine, muscles, malpighian tubules, and hypoderm of larvae Chironomus plumosus. Hence, these are also called "Salivary gland chromosomes." These are found in insects of the order Diptera and Collembola; in certain organs of mammals; and synergids, antipodes of flowering plants. Polytene chromosomes are also regularly...
02:05Duplication of Chromatin Structure
The process of chromosome duplication during cell division requires genome-wide disruption and re-assembly of chromatin. The chromatin structure must be accurately inherited, reassembled, and maintained in the daughter cells to ensure lineage propagation.
The basic unit of the chromatin is the nucleosome, consisting of DNA wrapped around octameric histone proteins and short stretches of linker DNA separating individual nucleosomes. The histone proteins within the nucleosome have their...
