    Abstract The transplantation of healthy hematopoietic stem cells (HSCs) contained in the bone marrow is a frontline treatment option for hematopoietic diseases. Detailed analysis of post-transplant HSC kinetics is crucial as the initial engraftment of HSCs influences prognosis. Dong et al. have explored the dynamic change in HSC cell fate upon bone marrow transplantation through the utilization of single-cell transcriptomic analysis.

    Abstract Hematopoietic stem cell (HSC) divisional fate and function are determined by cellular metabolism, yet the contribution of specific cellular organelles and metabolic pathways to blood maintenance and stress-induced responses in the bone marrow remains poorly understood. The outer mitochondrial membrane-localized E3 ubiquitin ligase MITOL/MARCHF5 (encoded by the Mitol gene) is known to regulate mitochondrial and endoplasmic reticulum (ER) interaction and to promote cell survival. Here, we investigated the functional involvement of MITOL in HSC maintenance by generating MX1-cre inducible Mitol knockout mice. MITOL deletion in the bone marrow resulted in HSC exhaustion and impairment of bone marrow reconstitution capability in vivo. Interestingly, MITOL loss did not induce major mitochondrial dysfunction in hematopoietic stem and progenitor cells. In contrast, MITOL deletion induced prolonged ER stress in HSCs, which triggered cellular apoptosis regulated by IRE1α. In line, dampening of ER stress signaling by IRE1α inihibitor KIRA6 partially rescued apoptosis of long-term-reconstituting HSC. In summary, our observations indicate that MITOL is a principal regulator of hematopoietic homeostasis and protects blood stem cells from cell death through its function in ER stress signaling.

    Abstract Previously we reported that, lactic acid bacteria (LAB) can induce human dermal fibroblast (HDF) cells to form multipotent cell clusters which are able to transdifferentiate into three germ layer derived cell lineages. Later on, we confirmed that ribosome is responsible for the LAB-induced transdifferentiation and ribosomes from diverse organisms can mimic the LAB effect on HDF cells. In our present study we have shown that, upon incorporation of ribosomes, non-small cell lung cancer cell line A549 and gastric tubular adenocarcinoma cell line H-111-TC are transformed into spheroid like morphology those can be transdifferentiated into adipocytes and osteoblast. Our qPCR analysis has revealed that, during the formation of ribosome induced cancer cell spheroids, the expression of the cancer cell associated markers and cell cycle/proliferation markers were altered at different time point. Through our investigation, here we report a novel and a non-invasive approach for cancer cell reprogramming by incorporating ribosomes.

    Abstract Although ribosomes are generally known to be a translational machinery, some ribosomal proteins also have accessory functions involving early development and differentiation. Previously, we reported that ribosome incorporation into human dermal fibroblasts generated embryoid body-like cell clusters, altered cellular fate, and differentiated into cells of all 3 germ layers. However, the molecular phenomena induced by ribosome incorporation in the cell remained unknown. Here, we demonstrate that ribosome incorporation into human breast cancer cell MCF7 leads to ribosome-induced cell clusters (RICs) formation accompanying with epithelial-mesenchymal transition (EMT)-like gene expression. Following ribosome incorporation, MCF7 cells cease proliferation, which is caused by inhibition of cell cycle transition from G0 to G1 phase. Further, MCF7 RICs show induced expression of EMT markers, TGF-β1 and Snail along with autophagy markers and tumor suppressor gene p53. These findings indicate that the incorporation of ribosome into cancer cells induces an EMT-like phenomenon and changes the cancer cell characteristics.

    Abstract Tsukushi (TSK) is a small signaling molecule which takes part in different developmental processes of multiple vertebrate organisms. The diverse activity of TSK depends on its ability to bind various intermediate molecules from different major signaling pathways. Interactions of TSK with BMP, FGF, TGF-β and Wnt pathways have already been confirmed. In this review, we will introduce the latest information regarding the involvement of TSK in developmental events. We suggest a fine tuning role for TSK in multiple signaling cascades. Also, we recommend further studies on the developmental role of TSK to fully reveal its potential.

    Abstract Secreted proteoglycan molecule Tsukushi (TSK) regulates various developmental processes, such as early body patterning and neural plate formation by interacting with major signaling pathways like Wnt, BMP, Notch etc. In central nervous system, TSK inhibits Wnt signaling to control chick retinal development. It also plays important roles for axon guidance and anterior commissure formation in mouse brain. In the present study, we investigated the role of TSK for the development and proper functioning of mouse hippocampus. We found that TSK expression is prominent at hippocampal regions of early postnatal mouse until postnatal day 15 and gradually declines at later stages. Hippocampal dimensions are affected in TSK knockout mice (TSK-KO) as shown by reduced size of hippocampus and dentate gyrus (DG). Interestingly, neural stem cell (NSC) density at the neural niche of DG was higher in TSK-KO compared with wild-type. The ratio of proliferating NSCs as well as the rate of overall cell proliferation was also higher in TSK-KO hippocampus. Our in vitro study also suggests an increased number of neural stem/progenitor cells residing in TSK-KO hippocampus. Finally, we found that the terminal differentiation of NSCs in TSK-KO was disturbed as the differentiation to neuronal cell lineage was increased while the percentages of astrocytes and oligodendrocytes were decreased. Overall, our study establishes the involvement of TSK in hippocampal development, NSC maintenance and terminal differentiation at perinatal stages.

    Abstract In order to support bone marrow regeneration after myeloablation, hematopoietic stem cells (HSCs) actively divide to provide both stem and progenitor cells. However, the mechanisms regulating HSC function and cell fate choice during hematopoietic recovery remain unclear. We herein provide novel insights into HSC regulation during regeneration by focusing on mitochondrial metabolism and ATP citrate lyase (ACLY).

    Abstract Ribosomes are intracellular organelles ubiquitous in all organisms, which translate information from mRNAs to synthesize proteins. They are complex macromolecules composed of dozens of proteins and ribosomal RNAs. Other than translation, some ribosomal proteins also have side-jobs called "Moonlighting" function. The majority of these moonlighting functions influence cancer progression, early development and differentiation. Recently, we discovered that ribosome is involved in the regulation of cellular transdifferentiation of human dermal fibroblasts (HDFs). In vitro incorporation of ribosomes into HDFs arrests cell proliferation and induces the formation of cell clusters, that differentiate into three germ layer derived cells upon induction by differentiation mediums. The discovery of ribosome induced transdifferentiation, that is not based on genetic modification, find new possibilities for the treatment of cancer and congenital diseases, as well as to understand early development and cellular lineage differentiation.
