OBJECTIVES@#The biomarkers targeting colorectal cancer (CRC) prognosis are short of high accuracy and sensitivity in clinic. Through bioinformatics analysis, we aim to identify and confirm a series of key genes referred to the diagnosis and prognosis of CRC.@*METHODS@#GSE31905, GSE35279, and GSE41657 were selected as complete RNA sequencing data sets of CRC and colorectal mucosa (CRM) tissues from the NCBI-GEO database, and the differentially expressed genes (DEGs) were analyzed. The common DEGs in these 3 data sets were obtained by Venn map, and enriched by STRING network system and Cytoscape software. The Kaplan-Meier plotter website was used to verify the correlation between the enriched genes and the prognosis of CRC.@*RESULTS@#For the whole RNA sequencing data sets of CRC and normal intestinal mucosa samples, the DEGs of CRC and CRM in the 3 data sets (|log@*CONCLUSIONS@#The above 11 genes verified by bioinformatics retrieval and analysis can predict the poor prognosis of CRC to a certain extent, and they provide a possible target for the diagnosis and treatment of CRC.

Formins are widely distributed in eukaryotes such as fungi, plants and animals. They play crucial roles in regulating the polymerization of actin, coordinating the synergistic interactions between actin and microtubules, and determining cell growth and morphology. Unlike formins from fungi and animals, plant formins have been evolved into two plant-specific types. Generally, type Ⅱ formins are believed to regulate the polarized growth of cells, and type Ⅰ formins may regulate the cell expansion and division processes. Recent studies on the function of plant formins suggest it is inappropriate to classify the function of formins purely based on their structures. This review summarizes the domain organization of formins and their corresponding functions, as well as the underpinning mechanisms. Furthermore, the unsolved or unexplored issues along with future perspectives on plant formins are proposed and discussed.

OBJECTIVE@#To deeply understand the clinical manifestation, laboratory examination characteristics, diagnosis and treatment of an eight p11 myeloproliferative syndrome (EMS) with rare phenotypes.@*METHODS@#The clinical and laboratory characteristics and the process of allogeneic hematopoietic stem cell transplantation (allo-HSCT) were summarized in 1 rare EMS case involving T/B/myeloid cells. Meanwhile, 2 similar cases in the previous literature were also discussed.@*RESULTS@#The bone marrow examination indicated that the patient with B-cell acute lymphocytic leukemia. The lymph node biopsy showed that the patient was T lymphoblastic/myeloid lymphoma. The 8p11 abnormality was found by the examination of bone marrow chromosomes. The RT-PCR examination showed that the BCR-ABL fused gene was negtive. The FGFR1 breakage was found by using the FISH with FGFR1 probe in lymph node. The Mutation of FMNL3, NBPF1 and RUNX1 genes was found by using the whole exome sequencing. The patient received allo-HSCT under CR2. By the follow-up till to September 2019, the patient survived without the above-mentioned disease.@*CONCLUSION@#EMS manifest as neoplasms involving T-lineage, B-lineage, and myeloid-lineage simultaneously is extremely rare. Although the FGFR1 gene-targeted therapy can be conducted, allo-HSCT should be actively considered.
