Publication date: Available online 3 November 2018Source: Journal of Genetics and GenomicsAuthor(s): Ying Cheng, Dahua ChenAbstractServed as a model organism over a century, fruit fly has significantly pushed forward the development of global scientific research, including in China. The high similarity in genomic features between fruit fly and human enables this tiny insect to benefit the biomedical studies of human diseases. In the past decades, Chinese biologists have used fruit fly to make numerous achievements on understanding the fundamental questions in many diverse areas of biology. Here, we review some of the recen...

Publication date: Available online 3 November 2018Source: Biochimica et Biophysica Acta (BBA) - Gene Regulatory MechanismsAuthor(s): Tina Lence, Chiara Paolantoni, Lina Worpenberg, Jean-Yves RoignantSummaryThe field of RNA modifications, so-called epitranscriptomics, has flourished over the past years owing to improvements of detection methods and the identification of important regulatory players. N6-methyladenosine (m6A) is the most abundant internal modification in messenger (mRNA) and long non-coding (lncRNA), and controls most steps of RNA metabolism. Its physiological roles range from gametogenesis, stem cell differe...

Abstract Cancer stem cells are the cancer cells that have abilities to self-renew, differentiate into defined progenies, and initiate and maintain tumor growth. They also contribute to cancer metastasis and therapeutic resistance, both of which are the major causes of cancer mortality. Among the reported makers of the cancer stem cells, CD133 is the most well-known marker for isolating and studying cancer stem cells in different types of cancer. The CD133high population of cancer cells are not only capable of self-renewal, proliferation, but also highly metastatic and resistant to therapy. Despite very limited inf...

(UCLA Samueli School of Engineering) A cancer therapy based on fusing two types of cells into a single unit shows promise in strengthening existing treatments for acute myeloid leukemia. The approach joins blood platelets that carry cancer drugs with stem cells that guide the platelets into bone marrow where leukemia begins.

Authors: Tang B, Liang W, Liao Y, Li Z, Wang Y, Yan C Abstract Liver metastasis is one of the major causes of death in patients with colorectal cancer, and although treatment has improved recently, the long‑term survival rate of patients has not improved significantly. In the present study, we used immunohistochemistry to determine that phosphoprotein enriched in astrocytes‑15 kDa (PEA15) was highly expressed in colorectal cancer tissues and liver metastatic cancer tissues. It was also highly expressed in metastatic colorectal cancer patients compared to non‑metastatic patients. Through clinicopathologic...

CONCLUSIONS: although the aggressiveness of treatment affects quality of life, patients consider it satisfactory after the first year. There are few significant differences between autologous and allogenic patients, and both groups have recovered in the course of the process. PMID: 30379249 [PubMed - in process]

This study indicates that PDGFRβ and TGFβ-TGFβR signaling cooperatively promote the differentiation of MSCs into CAFs in tumor microenvironments independently of canonical PDGF-PDGFR signaling. We propose that blockade of the interaction between PDGFRβ and TGFβR is a potential strategy to prevent TGFβ-mediated differentiation of MSCs into CAFs. PMID: 30344924 [PubMed]

In this report, we propose that the molecular mechanisms of beneficial actions of CR should be classified and discussed according to whether they operate under rich or insufficient energy resource conditions. Future studies of the molecular mechanisms of the beneficial actions of CR should also consider the extent to which the signals/factors involved contribute to the anti-oxidative, anti-inflammatory, anti-tumor and other CR actions in each tissue or organ, and thereby lead to anti-aging and prolongevity.
