New Transferrin Receptor-Targeted Peptide-Doxorubicin Conjugates: Synthesis and In Vitro Antitumor Activity.

Poor selectivity to tumor cells is a major drawback in the clinical application of the antitumor drug doxorubicin (DOX). Peptide-drug conjugates (PDCs) constructed by modifying antitumor drugs with peptide ligands that have high affinity to certain overexpressed receptors in tumor cells are increasingly assessed for their possibility of tumor-selective drug delivery. However, peptide ligands composed of natural L-configuration amino acids have the defects of easy enzymatic degradation and insufficient biological stability.

Gene pyramiding for boosted plant growth and broad abiotic stress tolerance.

Abiotic stresses such as salinity, heat and drought seriously impair plant growth and development, causing a significant loss in crop yield and ornamental value. Biotechnology approaches manipulating specific genes prove to be effective strategies in crop trait modification. The Arabidopsis vacuolar pyrophosphatase gene AVP1, the rice SUMO E3 ligase gene OsSIZ1 and the cyanobacterium flavodoxin gene Fld have previously been implicated in regulating plant stress responses and conferring enhanced tolerance to different abiotic stresses when individually overexpressed in various plant species.

Additive screening and formula optimization of microbial inhibitor having disease prevention and growth promotion effects on .

Antagonistic activity of the tested bacterium and cell-free fermentation liquid against pathogenic fungi was evaluated on potato dextrose agar (PDA) substratum plates by dual culture technique. Oxford cup method was used to measure antagonistic reaction between screened bacteria.

Room Temperature Broadband BiTe/PbS Colloidal Quantum Dots Infrared Photodetectors.

Lead sulfide colloidal quantum dots (PbS CQDs) are promising optoelectronic materials due to their unique properties, such as tunable band gap and strong absorption, which are of immense interest for application in photodetectors and solar cells. However, the tunable band gap of PbS CQDs would only cover visible short-wave infrared; the ability to detect longer wavelengths, such as mid- and long-wave infrared, is limited because they are restricted by the band gap of the bulk material. In this paper, a novel photodetector based on the synergistic effect of PbS CQDs and bismuth telluride (BiTe) was developed for the detection of a mid-wave infrared band at room temperature.

Dry matter recovery, ensiling characteristics and aerobic stability of oat silage treated with microbial inoculants at different temperatures.

To evaluate the effects of temperature and lactic acid bacteria (LAB) inoculants on oat silage in Loess Plateau of China, oat was harvested at dough stage, inoculated without (Control) or with LAB inoculants Synlac I (SLI, and ) and a selected strain HT1 () and ensiled at 25°C (T25), 35°C (T35) and 45°C (T45). The fermentation quality was measured after 60 d of ensiling and the aerobic exposure was conducted at 30°C for 9 d. The results showed that control silage (stored at 25°C) had better fermentation quality than that ensiled at 35°C or 45°C.

Key factors for differential drought tolerance in two contrasting wild materials of Artemisia wellbyi identified using comparative transcriptomics.

Background: Drought is a significant condition that restricts vegetation growth on the Tibetan Plateau. Artemisia wellbyi is a unique semi-shrub-like herb in the family Compositae, which distributed in northern and northwest of Tibetan Plateau. It is a dominant species in the community that can well adapt to virous environment stress, such as drought and low temperature.

Effects of Oat Varieties and Growing Locations on Seed-Borne Fungal Communities.

Many species of seed-borne fungi are closely allied with seed varieties and growing regions, including many seed-borne pathogens, but their species richness and distribution remain largely unknown. This study was conducted to explore the seed-borne fungal composition, abundance and diversity in (B7) and (B2) seed samples collected from Baicheng (BB), Dingxi (DB) and Haibei (HB) city, using Illumina sequencing techniques. Our results show that a total of 543,707 sequences were obtained and these were assigned to 244 operational taxonomic units (OTUs) with 97% similarity.

First Report of Leaf Spot Caused by Alternaria brassicae on Avena sativa in China.

Oat (Avena sativa) is an annual gramineous crop, which contains a source of soluble dietary fiber, β-glucan, unsaturated fatty acids, vitamins, minerals, phenolic acids and avenanthramides. It widely cultivated in cool and semi-arid areas in northern China (Li et al, 2017).

Transferrin Receptor Targeted Cellular Delivery of Doxorubicin Via a Reduction-Responsive Peptide-Drug Conjugate.

Purpose: Transferrin receptors (TfRs) are overexpressed in tumor cells but are scarce in normal tissues, which makes TfR an attractive target for drug treatment of cancer. The objective of this study was to evaluate the potential of BP9a (CAHLHNRS) as a peptide vector for constructing TfR targeted peptide-drug conjugates and selective drug delivery.

Methods: Doxorubicin (DOX) was connected to BP9a via a disulfide-intercalating linker to afford a reduction-responsive BP9a-SS-DOX conjugate.

Design, synthesis, and in vitro antitumor activity of a transferrin receptor-targeted peptide-doxorubicin conjugate.

In this study, a peptide-drug conjugate was designed and synthesized by connecting a transferrin receptor (TfR)-targeted binding peptide analog BP9a (CAHLHNRS) with doxorubicin (DOX) through N-succinimidyl-3-maleimidopropionate (SMP) as the cross-linker. Confocal laser scanning microscopy results indicated that free DOX mainly accumulated in the nuclei of both TfR overexpressed HepG2 hepatoma cells and L-O2 normal liver cells expressing low level of TfR; most of the BP9a-DOX conjugate displayed cytoplasmic location, and its cellular uptake by HepG2 cells was obviously reduced by TfR blockage test. Nevertheless, the cellular uptake of this conjugate by L-O2 cells was much less than that of free DOX.
