Neural crest cells (NCCs) are a transient, migratory cell population, which originates during neurulation at the neural folds and contributes to the majority of tissues, including the mesenchymal structures of the craniofacial skeleton. The deregulation of the complex developmental processes that guide migration, proliferation, and differentiation of NCCs may result in a wide range of pathological conditions grouped together as neurocristopathies. Recently, due to their multipotent properties neural crest stem cells have received considerable attention as a possible source for stem cell based regenerative therapies. This exciting prospect underlines the need to further explore the developmental programs that guide NCC differentiation. This review explores the particular importance of ribosome biogenesis defects in this context since a specific interface between ribosomopathies and neurocristopathies exists as evidenced by disorders such as Treacher-Collins-Franceschetti syndrome (TCS) and Diamond-Blackfan anemia (DBA).

Heart transplantation remains the ultimate treatment strategy for neonates and children with medically refractory end-stage heart failure and utilization of donors after circulatory death (DCD) can expand th donor pool. We have previously shown that mitochondrial transplantation preserves myocardial function and viability in neonatal swine DCD hearts to levels similar to that observed in donation after brain death (DBD). Herein, we sought to investigate the transcriptomic and proteomic pathways implicated in these phenotypic changes using ex situ perfused swine hearts.

Background: The dysregulation of ribosome biogenesis has been extensively identified in various cancers, making it emerge as a hallmark of malignant cells. This highlights the potential of targeting ribosome biogenesis as an effective approach for treating cancer patients. Although chemotherapy drugs including doxorubicin and cisplatin often target ribosome biogenesis to induce DNA damage or inhibit tumor cell proliferation, they are associated with significant side effects.

Maintenance and exit from pluripotency of embryonic stem cells (ESCs) are controlled by highly coordinated processes of protein synthesis and ribosome biogenesis (RiBi). ESCs are characterized by low rates of global protein synthesis and high levels of RiBi. Transient reduction of RiBi is a characteristic molecular event during the exit from pluripotency, of which the regulatory mechanism is unclear.

Moderating the pool of active ribosomal subunits is critical for maintaining global translation rates. A factor crucial for modulating the 60S ribosomal subunit is eukaryotic translation initiation factor-6 (eIF6). Release of eIF6 from the 60S subunit is essential to permit 60S interactions with the 40S subunit.
