Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization

open access: yesAdvanced Science, EarlyView.
This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...

Extragonadal germ-cell tumors – a review of the pathogenesis, histopathological findings, diagnosis and treatment [PDF]

open access: yesArchives of the Balkan Medical Union, 2019
Primary extragonadal germ-cell tumors (EGCTs) are a rare group of neoplasms, that can exist anywere along the midline of the body, without the evidence of a primary gonadal tumor.

Cell division promotes efficient retrotransposition in a stable L1 reporter cell line [PDF]

open access: yes, 2013
Background: Long interspersed element type one (L1) actively modifies the human genome by inserting new copies of itself. This process, termed retrotransposition, requires the formation of an L1 ribonucleoprotein (RNP) complex, which must enter the ...

Testicular mRNA‐LNP Delivery: A Novel Therapy for Genetic Spermatogenic Disorders

open access: yesAdvanced Science, EarlyView.
In the current study, we developed a novel therapy for genetic spermatogenic disorders. It was revealed that in vivo delivery of mRNA LNP3 could restore spermatogenesis in Msh5D486Y/D486Y and Maps KO mouse models with meiotic arrest. Notably, the offspring without genomic integration was born using ICSI derived from the rescue of Msh5D486Y/D486Y mouse ...

Embryonic Stem Cells and the Germ Cell Lineage

open access: yes, 2011
Stem cells possess the unique ability to either propagate by self-renewal or to differentiate to mature tissues under the influence of appropriate molecular cues. This remarkable feature, also termed “stem cell potency” has been the focus of both a historical and current research spotlight on stem cells, and particularly the potential for human stem ...

Comprehensive Profiling of N6‐methyladnosine (m6A) Readouts Reveals Novel m6A Readers That Regulate Human Embryonic Stem Cell Differentiation

open access: yesAdvanced Science, EarlyView.
This research deciphers the m6A transcriptome by profiling its sites and functional readout effects: from mRNA stability, translation to alternative splicing, across five different cell types. Machine learning model identifies novel m6A‐binding proteins DDX6 and FXR2 and novel m6A reader proteins FUBP3 and L1TD1.

Establishment of a Human Embryonic Germ Cell Line and Comparison with Mouse and Human Embryonic Stem Cells

open access: yesMolecules and Cells, 2004
Human embryonic stem (ES) cells and embryonic germ (EG) cells are pluripotent and are invaluable material for in vitro studies of human embryogenesis and cell therapy. So far, only two groups have reported the establishment of human EG cell lines, whereas at least five human ES cell lines have been established.

Pluripotent human stem cells: Standing on the shoulders of giants [PDF]

open access: yes, 2016
The advent of human pluripotent stem cells, with the first derivation of human embryonic stem cells in 1998, and of human induced pluripotent stem cells in 2007, has ushered in an era of considerable excitement about the prospects of using these cells to

Integrated Single‐Cell and Spatial Transcriptomics Reveal Cell‐Type‐Specific Immune Regulatory Networks in Maize Responding to Southern Corn Rust

open access: yesAdvanced Science, EarlyView.
By integrating single‐nuclei and spatial transcriptomics, this study presents a stereoscopic landscape of maize leaf to Puccinia polysora infection. Epidermal and mesophyll cells initiate primary defenses via RLPs/RLKs and jasmonic acid signaling. Cell‐cell communication analyses further reveal the underlying the dynamics of the underlying immune ...

Primary embryonal carcinoma of the prostate

open access: yesUrology Case Reports
Extragonadal germ cell tumors originating in the prostate are extremely rare. Thus far, less than 20 cases were described in the literature. To our knowledge, there are no published cases of primary embryonal carcinoma of the prostate.
