Genome-Wide Transcriptional Profiling and Functional Analysis Reveal That OsPHT4;4 Is Critical for the Growth and Development of Rice.

Phosphorus (P) is an essential macronutrient required for various vital processes in crop growth and development, including signal transduction, CO fixation, and photosynthetic phosphorylation. Phosphate transporters (PHTs) in plants play critical roles in the uptake, distribution, and internal transport of Phosphate (Pi). Among these transporters, the PHT4 family is widely distributed across plant species; however, the specific functions of many members within this family remain to be fully elucidated.

Successive Years of Rice Straw Return Increased the Rice Yield and Soil Nutrients While Decreasing the Greenhouse Gas Intensity.

Straw return has important impacts on black soil protection, food security, and environmental protection. One year of straw return (S1) reduces rice yield and increases greenhouse gas (GHG) emissions. However, the effects of successive years of straw return on rice yield, soil nutrients, and GHG emissions in the northeast rice region are still unclear.

A prognostic model for Schistosoma japonicum infection-associated liver hepatocellular carcinoma: strengthening the connection through initial biological experiments.

Background: Numerous studies have shown that Schistosoma japonicum infection correlates with an increased risk of liver hepatocellular carcinoma (LIHC). However, data regarding the role of this infection in LIHC oncogenesis are scarce. This study aimed to investigate the potential mechanisms of hepatocarcinogenesis associated with Schistosoma japonicum infection.

Serum cytokine biosignatures for identification of tuberculosis among HIV-positive inpatients.

Background: Serum cytokines correlate with tuberculosis (TB) progression and are predictors of TB recurrence in people living with HIV. We investigated whether serum cytokine biosignatures could diagnose TB among HIV-positive inpatients.

Methods: We recruited HIV-positive inpatients with symptoms of TB and measured serum levels of inflammation biomarkers including IL-2, IL-4, IL-6, IL-10, tumour necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ).

-Glycosylation of LRP6 by B3GnT2 Promotes Wnt/β-Catenin Signalling.

Reception of Wnt signals by cells is predominantly mediated by Frizzled receptors in conjunction with a co-receptor, the latter being LRP6 or LRP5 for the Wnt/β-catenin signalling pathway. It is important that cells maintain precise control of receptor activation events in order to properly regulate Wnt/β-catenin signalling as aberrant signalling can result in disease in humans. Phosphorylation of the intracellular domain (ICD) of LRP6 is well known to regulate Wntβ-catenin signalling; however, less is known for regulatory post-translational modification events within the extracellular domain (ECD).

The use of multiplex imaging techniques to characterize tuberculous granuloma heterogeneity.

Caseous granulomas are pathological hallmarks of tuberculosis (TB), and increasing evidence suggests that TB granuloma composition is highly temporally and spatially heterogenous in both animal models and humans. Traditional pathological techniques are limited in their ability to reveal the heterogeneity present in TB granulomas. Multiplex tissue imaging tools combined with powerful, high resolution spatial analysis have enabled the detection of various cell phenotypes, aiding in the visualization of the granuloma complex and revealing the interactions between immune cells and nonimmune cells.

Does low-carbon city pilot affect the enterprise competitiveness in China? Based on a staggered difference-in-difference model.

China has recently instituted the low-carbon city pilot (LCCP) policy in target areas to control its greenhouse gas emissions. Studies examining those environmental regulations have not focused on how they affect enterprise competitiveness, especially emphasizing the LCCP's dynamic effect. Here, we use the quasi-experimental opportunities of the LCCP policy along with a staggered difference-in-difference model to evaluate and explain the influences and transmission mechanisms of the LCCP policy on enterprise competitiveness.

An Alternatively Spliced Variant of METTL3 Mediates Tumor Suppression in Hepatocellular Carcinoma.

Many post-transcriptional mRNA processing steps play crucial roles in tumorigenesis and the progression of cancers, such as N6-methyladenosine (mA) modification and alternative splicing. Upregulation of methyltransferase-like 3 (METTL3), the catalytic core of the mA methyltransferase complex, increases mA levels and results in significant effects on the progression of hepatocellular carcinoma (HCC). However, alternative splicing of METTL3 has not been fully investigated, and the functions of its splice variants remain unclear.

Long Noncoding RNAs Regulate the Inflammatory Responses of Macrophages.

Long noncoding RNAs (lncRNAs) are defined as transcripts with more than 200 nucleotides that have little or no coding potential. In recent years, due to the development of next-generation sequencing (NGS), a large number of studies have revealed that lncRNAs function as key regulators to maintain immune balance and participate in diverse physiological and pathological processes in the human body. Notably, overwhelming evidence suggests that lncRNAs can regulate innate immune responses, the differentiation and development of immune cells, inflammatory autoimmune diseases, and many other immunological processes with distinct regulatory mechanisms.

Elevated HB-EGF expression in neural stem cells causes middle age obesity by suppressing Hypocretin/Orexin expression.

Obesity is common in the middle aged population and it increases the risks of diabetes, cardiovascular diseases, certain cancers, and dementia. Yet, its etiology remains incompletely understood. Here, we show that ectopic expression of HB-EGF, an important regulator of neurogenesis, in Nestin neuroepithelial progenitors with the Cre-LoxP system leads to development of spontaneous middle age obesity in male mice accompanied by hyperglycemia and insulin resistance.

The momentous role of N6-methyladenosine in lung cancer.

Lung cancer is the leading cause of cancer death worldwide. Although diagnostic methods and targeted drugs have been rapidly developed in recent years, the underlying molecular mechanisms in the pathogenesis of lung cancer remain enigmatic. The N6-methyladenosine (m A) modification is the most common modification of messenger RNA in eukaryotes and plays critical roles in many diseases, especially cancers.

Determination of Scrub typhus Suggests a New Epidemic Focus in the Anhui Province of China.

In 2007, 19 cases of a scrub typhus epidemic occurred within a week at a sports school in Mingguang County, Anhui Province, where no previous incidence of this mite borne disease had been reported. Sero-surveillance in 2009 indicated that 10 of the 100 school students possessed anti-Orientia tsutsugamushi antibodies. From 2009 to 2013, 60 small animals and 2250 mites were collected in the vicinity of the school.
