Elderly Hodgkin lymphoma (HL) is an aggressive lymphoma subgroup with high 18F-FDG avidity at 18F-FDG-PET/CT but no shared criteria for PET/CT in treatment evaluation and prediction of outcome are available. The aim of our bicentric study was to investigate whether the metabolic baseline PET/CT parameters can predict treatment response and prognosis in elderly HL. We retrospectively included 123 patients who underwent baseline 18F-FDG-PET/CT and end of treatment PET/CT scans. The PET images were analyzed visually and semi-quantitatively by measuring the lesion to liver SUVmax ratio (L-L SUV R), lesion to blood-pool SUVmax ratio (L-BP SUV R), metabolic tumor volume (MTV), and total lesion glycolysis (TLG). Survival curves were plotted according to the Kaplan-Meier method. At a median follow-up of 40 months, the median PFS and OS were 29 and 37 months. L-BP SUV R, L-L SUV R, MTV, and TLG were significantly higher in patients with no complete response compared with complete response group at end of treatment. Moreover, these parameters were demonstrated to be independent prognostic factors for PFS together with tumor stage, while only L-L SUV R and L-BP SUV R for OS. End of treatment PET/CT results using Deauville criteria were significantly correlated with outcome survival. End of treatment PET/CT results (using Deauville criteria) and semiquantitative baseline PET/CT parameters were significantly correlated with response to treatment and long-term outcome.Coagulative dysfunction is frequently observed among patients with extranodal nasal-type natural killer/T cell lymphoma (NKTCL) in our clinical practice. However, the true prognostic value of coagulation factors in patients with NKTCL has not been evaluated systemically. Data for patients with stage I/II NKTCL who were treated in the Cancer Hospital, Chinese Academy of Medical Sciences, from January 2008 to January 2019 were collected retrospectively. The patients enrolled in this study were initially diagnosed as having early-stage disease. The patients’ baseline characteristics and pretreatment laboratory tests for coagulation function, including fibrinogen (FIB) and D-dimer (D-D), were reviewed and analyzed. The influence of coagulative factors on the responses and prognosis of patients with early-stage NKTCL was evaluated. Among 394 patients assessed, 154 were included in this study. Abnormal coagulation function was found in nearly half of the patients (48.1%). Univariate analysis showed that reduced complete remission (CR) was associated with elevated D-D (P = 0.001) and elevated FIB levels (P = 0.006). The D-D level was demonstrated as associated with unfavorable progression-free survival (PFS) (P = 0.003) and overall survival (OS) (P = 0.002). Multivariate analysis indicated that an elevated D-D level was an independent factor for poor clinical response (P = 0.019), PFS (P = 0.046), and OS (P = 0.024). Elevated pretreatment levels of coagulation factors, especially D-D and plasma FIB, are unfavorable predictors for clinical response, OS, and PFS in early-stage NKTCL.This is the first evidence that replicating vectors can be successfully used for transient protein expression in BY-2 plant cell packs. Transient recombinant protein expression in plants and recently also plant cell cultures are of increasing interest due to the speed, safety and scalability of the process. Currently, studies are focussing on the design of plant virus-derived vectors to achieve higher amounts of transiently expressed proteins in these systems. Here we designed and tested replicating single and multi-cassette vectors that combine elements for enhanced replication and hypertranslation, and assessed their ability to express and particularly co-express proteins by Agrobacterium-mediated transient expression in tobacco BY-2 plant cell packs. Substantial yields of green and red fluorescent proteins of up to ~ 700 ng/g fresh mass were detected in the plant cells along with position-dependent expression. This is the first evidence of the ability of replicating vectors to transiently express proteins in BY-2 plant cell packs.MsCBL4 expression in tobacco enhanced its salt and saline-alkali stress tolerance by regulating calcium accumulation in roots, indicating the important role of calcium metabolism in plant saline-alkali stress tolerance The calcineurin B-like (CBL) family of proteins play important roles in plant abiotic stress tolerance and signal transduction. CBL4 is known to participate in the Salt Overly Sensitive pathway; however, little is currently known regarding the mechanisms underlying the response of CBL4 to saline-alkali stress. In this study, we cloned and characterized the alfalfa MsCBL4 gene. We found that MsCBL4 showed the highest expression in root tissues and was induced by salt and saline-alkali stress, with the latter causing higher induction. Ulixertinib Overexpression of MsCBL4 in tobacco enhanced salt and saline-alkali stress tolerance and reduced the Na+/K+ ratio in roots of transgenic lines. Salt (30 and 300 mM NaCl) and saline-alkali (30 mM NaHCO3) stress assays performed for MsCBL4 transgenic tobacco lines revealed a substantial influx of sodium ions in roots under saline-alkali stress and indicated that the expression of MsCBL4 had little influence on sodium ion content reduction. In contrast, in roots subjected to saline-alkali stress, calcium accumulation occurred and was significantly enhanced by the overexpression of MsCBL4. Physiological and biochemical analyses indicated that MsCBL4 plays an important role in saline-alkali stress tolerance via its influence on the regulation of calcium transport and accumulation. These results provide novel insights into the saline-alkali stress tolerance mechanisms of plants.Overexpression of CpbHLH1 in Arabidopsis and tobacco resulted in a dramatic decrease in anthocyanin accumulation by repressing the expression of late biosynthesis genes in the flavonoid biosynthesis pathway. Many basic helix-loop-helix (bHLH) transcription factors (TFs) of subgroup IIIf have been characterized as anthocyanin-associated activators in higher plants, but information regarding bHLH TFs that inhibit anthocyanin accumulation remains scarce. In this study, the subgroup IIIf bHLH TF CpbHLH1 from Chimonanthus praecox (L.) was identified as a negative regulator of anthocyanin accumulation. Our results showed that overexpression of CpbHLH1 in model plant species, Arabidopsis and tobacco, resulted in a dramatic decrease in anthocyanin content, whereas the content of proanthocyanidin was little affected. Quantitative RT-PCR (qRT-PCR) assays of the structural genes in the flavonoid biosynthesis pathway revealed that CpbHLH1 inhibits anthocyanin accumulation mainly through repressing the expression of late biosynthesis genes (LBGs).
