Genomic‐Guided Conservation Actions to Restore the Most Endangered Conifer in the Mediterranean Basin

open access: yesMolecular Ecology, Volume 34, Issue 23, December 2025.
ABSTRACT Species with extremely small population sizes are critically endangered because of reduced genetic diversity, increased inbreeding and hybridisation threats. Genomic tools significantly advance conservation by revealing genetic insights into endangered species, notably in monitoring frameworks.

Targeting RBM10‐Repressed RORB Activity in Liquid Condensates Inhibits Lysosomal Biogenesis and Neuroblastoma Progression via Affecting NF‐κB Signaling

open access: yesAdvanced Science, Volume 12, Issue 44, November 27, 2025.
This study identifies that RBM10 represses the transcriptional activity of RORB in liquid condensates, resulting in down‐regulation of NR1D1 and RIOK3 that further activates NF‐κB activity to facilitate lysosomal biogenesis and aggressive features of NB cells.

Chromosome counts of some Zingiberaceous species from Thailand [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2002
The data on chromosome numbers of 22 species belonging to 10 genera of Zingiberaceae distributed in Thailand were investigated. The somatic numbers range from 20 to 48 showing diploidy and polyploidy.

Structure of 5S rDNA sequence of the gibel carp (Carassius gibelio) with 2n=100 chromosomes

open access: yesFrontiers in Marine Science, 2015
In vertebrate, the 5S ribosomal DNA (rDNA) consists of a conserved coding (transcriptional) unit of 120 bp (5S), which is separated from the next unit by a nontranscribed spacer (NTS). The coding sequence and the NTS together form a repeat unit which can

Automictic Reproduction in Interspecific Hybrids of Poeciliid Fish [PDF]

open access: yes, 2007
SummaryAutomixis, the process whereby the fusion of meiotic products restores the diploid state of the egg, is a common mode of reproduction in plants but has also been described in invertebrate animals [1, 2].

The polyploid continuum and the landscape of polyploid genomic variation

open access: yesAmerican Journal of Botany, Volume 112, Issue 11, November 2025.
Abstract Polyploid research has traditionally distinguished between autopolyploids and allopolyploids on the basis of evolutionary origins, modes of inheritance, or chromosomal pairing behavior during meiosis. It has long been recognized, however, that a binary classification does not accurately reflect the complexity and diversity inherent to ...

Nuclear DNA Content of Fine Needle Aspirates of Invasive Ductal Carcinomas of the Breast

open access: yesAnalytical Cellular Pathology, 1997
Patients with aggressive breast cancers benefit from chemotherapy prior to surgery. If the biology of the breast cancers were better characterised pre‐operatively, more patients at risk could be offered chemotherapy.

Genetic Divergence and Antibody Expression Influence the N‐Glycomes of CHO‐K1 and CHO‐S Cells

open access: yesBiotechnology and Bioengineering, Volume 122, Issue 11, Page 3160-3175, November 2025.
ABSTRACT While Chinese hamster ovary (CHO) cells continue to be the workhorse of recombinant therapeutic protein production, decades of genetic divergence in the industrially relevant CHO‐K1 and CHO‐S cell lines, are likely to have resulted in differing glycosylation capabilities. Glycosylation can influence the efficacy, serum half‐life, and safety of

CHROMOSOME NUMBERS OF CHILEAN PTERIDOPHYTES: FIRST CONTRIBUTION NUMEROS CROMOSOMICOS DE PTERIDOFITOS CHILENOS: PRIMERA CONTRIBUCION

open access: yesGayana: Botanica, 2006
Mitotic chromosome counts in Chilean pteridophytes confirm the diploidy described for Equisetum L. (2n = 216) and Blechnum L. (2n = 66), as well as the tetraploidy of Asplenium L. (2n = 144). Megalastrum spectabile (Kaulf.) A.R.Sm.

Social Evolution: New Horizons [PDF]

open access: yes, 2014
Cooperation is a widespread natural phenomenon yet current evolutionary thinking is dominated by the paradigm of selfish competition. Recent advanced in many fronts of Biology and Non-linear Physics are helping to bring cooperation to its proper place ...
