Reduction of peritoneal cavity B1a cells in adult Slc7a5 knockdown mice via dysregulating the mTOR pathway.

Slc7a5 is an important amino acid transporter that is highly expressed in metabolically active and rapidly proliferating cells. To explore the effect of Slc7a5 on adult B cell development, we conditionally deleted Slc7a5 in murine B cells and observed a significant reduction of B1a cells. In contrast to PI3K-Akt pathway activation, activity of the mTOR pathway was decreased.

Aurora A kinase inhibition compromises its antitumor efficacy by elevating PD-L1 expression.

Aurora A plays a critical role in G2/M transition and mitosis, making it an attractive target for cancer treatment. Aurora A inhibitors showed remarkable antitumor effects in preclinical studies, but unsatisfactory outcomes in clinical trials have greatly limited their development. In this study, the Aurora A inhibitor alisertib upregulated programmed death ligand 1 (PD-L1) expression in a panel of tumor cells both in vitro and in vivo.

A review of the species group within the genus (Coleoptera, Chrysomelidae, Criocerinae).

A new species group of the genus Reitter, 1913 is proposed and reviewed, the group. It includes six species: Medvedev, 1958; (Baly, 1865); (Heyden, 1887); (Heyden, 1887); (Reitter, 1898) ; and (Pic, 1916). Among them, is resurrected as a valid species from synonymy with , and is newly reported from China.

 (Celastraceae): Rediscovered in flowering with respect to its taxonomy, nomenclature, and rarity.

A small population of (Celastraceae) with flowering plants was discovered more than 100 kilometers away from its type locality. The incomplete original description of this species is supplemented here with floral materials since it is known from only two gatherings of fruiting specimens. Its 5-merous flowers and two ovules per locule support its position in , and this inference is further reinforced by phylogenetic analysis based on the nuclear internal transcribed spacer (ITS) of rDNA.

Begoniafimbristipulasubsp.siamensis (sect. Diploclinium, Begoniaceae), a new taxon of the megadiverse genus endemic to Thailand.

The genus has not only been recognised to be one of the mega-diverse plant genera but also as one found to comprise many undiscovered species. In particular, the increase of extensive field surveys in tropical regions of Southeast Asia has added to the discovery of many new species that are often found only in a few localities. In this study, the new taxon Begoniafimbristipulasubsp.

 (Primulaceae), a new species of the primrose from Sichuan, China.

This paper describes and illustrates a new species of Primulaceae, from Wolong National Nature Reserve in Sichuan Province, China. It is very rare and currently only known from its type locality. The new species belongs to subsection Chartacea of the section Petiolares on account of lacking bud scales at flowering, being efarinose and having distinct petiolate leaves with more or less rounded lamina.

 (Poaceae, Bambusoideae), a new combination from Guangxi.

is transferred to the genus following a reassessment based on a new collection with pachymorph and long-necked rhizomes from its type locality in Guangxi, China. Morphologically, it is most similar to , but differs in culm, branch complement and foliage leaf characters. A revised description of its morphology and color photos are also provided.

The floral morphology of four Chinese species (Poaceae, Bambusoideae) previously described only from vegetative material.

Due to their specialised flowering biology where frequent or even annual flowering is uncommon, reproductive materials of bamboos are not always available, so hampering taxonomic interpretation and research into other aspects. , , and were established only based on vegetative materials and flowering or fruiting material has been hitherto unknown. The floral morphology of these four species is described for the first time and, correspondingly, epitypes are designated to support a more complete interpretation of the species.

Reinstatement of (Leguminosae-Caesalpinioideae) - the final piece in the Caesalpinia group puzzle.

A recent molecular phylogenetic analysis of the Caesalpinia group demonstrated that it comprises 26 genera, but the recognition of a putative 27 genus, , remained in doubt. This study presents a phylogenetic analysis of ITS and five plastid loci revealing a robustly supported monophyletic group representing the Ticanto clade, sister to the morphologically distinct genus . Based upon this evidence, along with a morphological evaluation, the genus is here reinstated.

First records of three species (Crustacea, Decapoda, Nematocarcinidae) in the deep-waters of the north-western Pacific.

Background: During two scientific expeditions in the South China Sea and the Kyushu-Palau Ridge area, several specimens of thread-leg shrimp were collected from deep waters. Amongst them, three species, Burukovsky, 2000, (Spence Bate, 1888) and Burukovsky, 2003 were newly recorded from the north-western Pacific. The morphological features of these specimens are in concordance with the original description.

Diversity and distribution of fish in the Qilian Mountain Basin.

The Qilian Mountain Basin, on the north-eastern edge of the Qinghai-Tibet Plateau (QTP), supports a high diversity of native and endemic fish. However, the detailed species inventory and distribution patterns concerning fish in the whole Basin remain unknown, which hinders the conservation of biodiversity and assessment of ecological health. We compiled a comprehensive species richness and distribution database of freshwater fish in the Qilian Mountain Basin, based on field investigations and exhaustive data collection from 50 rivers or lakes.

Review of Verrill, 1899 (Echinodermata, Ophiuroidea, Ophiacanthidae), description of new species in and , and new records from the Northwest Pacific and the South China Sea.

The ophiuroid genus is well characterized by the deep incisions in the disc. Prior to this study, it contained 32 accepted species, but species limits and geographic distributions were not well understood. The manned submersible vehicle 'Shenhaiyongshi' was used to collect ophiuroid specimens from the deep-sea seamounts and cold seeps in the South China Sea and Northwest Pacific at 602-3600 m depth, during 2018 to 2020.

MicroRNAs balance growth and salt stress responses in sweet sorghum.

Salt stress is one of the major causes of reduced crop production, limiting agricultural development globally. Plants have evolved with complex systems to maintain the balance between growth and stress responses, where signaling pathways such as hormone signaling play key roles. Recent studies revealed that hormones are modulated by microRNAs (miRNAs).
