Differential expression of conserved germ line markers and delayed segregation of male and female primordial germ cells in a hermaphrodite, the leech helobdella. [PDF]

open access: yes, 2013
In sexually reproducing animals, primordial germ cells (PGCs) are often set aside early in embryogenesis, a strategy that minimizes the risk of genomic damage associated with replication and mitosis during the cell cycle.

Evolving Lessons on Metazoan Primordial Germ Cells in Diversity and Development

open access: yesMolecular Reproduction and Development, Volume 92, Issue 5, May 2025.
ABSTRACT Germ cells are pivotal for the continuation of biological species. The metazoan germline develops from primordial germ cells (PGCs) that undergo multiple rounds of mitotic divisions. The PGCs are specified by either maternal inheritance of asymmetrically polarized cytoplasmic mRNAs/proteins (found in roundworms, flies, fishes, frogs, and fowl)

The Lokve Barite Deposit, Croatia: an Example of Early Diagenetic Sedimentary Ore Deposits

open access: yesGeologia Croatica, 2010
Syngenesis versus epigenesis in the Kupferschiefer genetic model is still a matter of controversy. The title of the article seems to be a paraphrase of a well-known paper by WEDEPOHL (1971), “Kupferschiefer as a prototype of syngenetic sedimentary ...

An Anaerobic Microbial Community Mediates Epigenetic Native Sulfur and Carbonate Formation During Replacement of Messinian Gypsum at Monte Palco, Sicily

open access: yesGeobiology, Volume 23, Issue 2, March/April 2025.
ABSTRACT The microbially mediated replacement of sulfate‐bearing evaporites by authigenic carbonate and native sulfur under anoxic conditions is poorly understood. Sulfur‐bearing carbonates from the Monte Palco ridge (Sicily) replacing Messinian gypsum were therefore studied to better characterize the involved microorganisms.

Association Between rs920778 Polymorphisms and Cancer Risk: An Updated Meta‐Analysis

open access: yesGenetics Research , Volume 2025, Issue 1, 2025.
Background: A growing number of studies are exploring the association between HOTAIR rs920778 polymorphisms and cancer risk, but to date, there has been controversy and uncertainty. Preliminary evidence suggests that this polymorphism may influence cancer susceptibility, particularly in Asian populations and specific cancer types such as cervical ...
