C-banding, fluorescent staining and NOR location in holokinetic chromosomes of bugs of the Neotropical genus Antiteuchus (Heteroptera: Pentatomidae: Discocephalinae)

European Journal of Entomology, 2006
Different cytogenetic techniques including C-banding, base-specific fluorochromes and silver nitrate staining were used to compare the karyotypes of three species of bugs, representatives of the Neotropical genus Antiteuchus, namely A.

Quantitative Analysis of Constitutive Heterochromatin in Couples with Fetal Wastage

American Journal of Reproductive Immunology, 1997
PROBLEM: Heteromorphism of constitutive heterochromatin is a stable evolutionary feature that is thought to cause no phenotypic alterations. Nevertheless, the role of constitutive heterochromatin is still unknown. The instability of constitutive heterochromatin was generally restricted to T‐lymphocytes and was associated with variable immunodeficiency.

Nortriptyline Inhibits Lysosomal Exocytosis‐Mediated SASP During Gastric Cancer Progression via Targeting HOXA1‐PITX2 Phase Separation

Advanced Science, Volume 12, Issue 46, December 11, 2025.
This study identifies that HOXA1 facilitates transcriptional activity of PITX2 in liquid condensates, resulting in up‐regulation of MCOLN1 and RAB3A followed by lysosomal exocytosis of LGALS1 and IGFBP7 from senescent cells, thus activating AKT signaling and EMT.

Chromosome banding of two Litoria species (Anura, Hylidae) [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2013
This research was the first cytogenetic studies of green-eyed tree frog (Litoria genimaculata) and Nyakala frog(L. nyakalensis). The mitotic chromosomes were prepared directly from bone marrow after in vivo colchicine treatment andanalysed following ...

Constitutive heterochromatin distribution in pig (Sus scrofa) chromosomes

Caryologia, 1998
Constitutive heterochromatin (HC = C-banding) distribution was studied in pig (Sus5crofa) chromosomes from 20 animals belonging to Cinta Senese and Calabrese breeds raised in southern Italy. The use of CBG-banding, sequential GBG/CBA-banding and sequential GBG/ Ag-NOR/CBA-banding techniques allowed more detailed characterization of C-banding patterns ...

Preventing Neurons and Glial Cells Destruction in Substantia Nigra Pars Compacta and Striatum Using St. John's Wort and Stem Cells on Parkinson's Model

Brain and Behavior, Volume 15, Issue 12, December 2025.
‐ ABSTRACT Study Objective St. John's wort (Hypericum perforatum) has been used for centuries as a medicinal plant to remedy external disorders such as burns and wounds, as well as internal disorders such as nerve pain, anxiety, and depression. Bone marrow mesenchymal stem cells (BMSCs) are a heterogeneous population of pluripotent stromal cells that ...

Constitutive heterochromatin in chromosomes of duck hybrids and goose hybrids

Poultry Science, 2017
Constitutive heterochromatin is a highly condensed fraction of chromatin in chromosomes. It is characterized by a high degree of polymorphism. Heterochromatin is located in the centromeric, telomeric, and interstitial parts of chromosomes. We used the CBG ( C: banding using B: arium hydroxide by G: iemsa) staining technique to identify heterochromatin ...

The Aging Gut–Brain Axis: Effects of Dietary Polyphenols and Metal Exposure

Chronic Diseases and Translational Medicine, Volume 11, Issue 4, Page 251-268, December 2025.
The influence of gut microbiota on brain health ABSTRACT Diet provides essential metals, which are required for the growth, development, and well‐functioning of the body. Nonetheless, some natural and human activities add toxic heavy metals to the diet, consequently introducing them to our bodies, resulting in several disorders and death. The intestine,

CHARACTERIZATION OF HUMAN CHROMOSOMAL CONSTITUTIVE HETEROCHROMATIN

Gulustan-Black Sea Scientific Journal of Academic Research, 2020
Heterochromatin of centromeric chromosome regions contains late replicating, largely repetitive DNA. It is suggested that heterochromatin participates in chromosome pairing, crossing-over and in chromosome disjunction control (1,3). Centromeric heterochromatin, a variety of heterochromatin, is a tightly packed form of DNA.Centromeric heterochromatin is
