Distribution of constitutive heterochromatin in Triatoma melanocephala (Hemiptera, Triatominae)

Genetics and Molecular Research, 2014
In principle, Triatoma melanocephala was included in the Brasiliensis subcomplex on the basis of morphological parameters and geographical layout, since there were no other relevant data available in the literature. On the basis of karyotype, it has been proposed to exclude T. melanocephala, as well as of T. vitticeps and T.

ATRX: From Chromatin Remodeling to Disease

genesis, Volume 63, Issue 6, December 2025.
ABSTRACT Chromatin remodeling proteins are evolutionarily conserved factors involved in a wide range of biological processes. In this review, we describe ATRX, a chromatin remodeling protein belonging to the SWI/SNF2 family. Its association with different protein complexes, and its roles in embryonic development, sexual differentiation, as well as ...

Comparative cytogenetics in different populations of the cavernicolous diplopod Pseudonannolene strinatii (Diplopoda, Pseudonannolenidae)

Iheringia: Série Zoologia, 2013
Different populations of Pseudonannolene strinatii Mauriès, 1974 collected from three caves in Iporanga, state of São Paulo, were cytogenetically compared using techniques of conventional coloration, C-banding and silver nitrate impregnation.

Mechanical Signaling: Molecular Mechanisms, Biological Functions, Diseases, and Therapeutic Targets

MedComm, Volume 6, Issue 12, December 2025.
In this review, we summarize cell–ECM interactions and delve into the complex mechanotransduction. We introduce advanced research methods and emerging clinical tools used to study cellular mechanical phenotypes, mechanotransduction, and disease progression. Additionally, we analyze the role of mechanical biomarkers in the development and progression of

Alternative Splicing: Molecular Mechanisms, Biological Functions, Diseases, and Potential Therapeutic Targets

MedComm, Volume 6, Issue 12, December 2025.
Alternative splicing (AS) expands proteomic diversity and functional complexity in eukaryotes, regulated by spliceosomal components, RNA elements, and epigenetic modifications. Dysregulated AS contributes to diseases, including cancer, neurodegenerative disorders, and cardiovascular conditions, among others. Therapeutic interventions, such as antisense
