Article Abstract

Bacterial blight (BB) of rice caused by pv. () is one of the most serious bacterial diseases that hinder the normal growth and production of rice, which greatly reduces the quality and yield of rice. The effect of traditional methods such as chemical control is often not ideal. A series of production practices have shown that among the numerous methods for BB controlling, breeding and using resistant varieties are the most economical, effective, and environmentally friendly, and the important basis for BB resistance breeding is the exploration of resistance genes and their functional research. So far, 44 rice BB resistance genes have been identified and confirmed by international registration or reported in journals, of which 15 have been successfully cloned and characterized. In this paper, research progress in recent years is reviewed mainly on the identification, map-based cloning, molecular resistance mechanism, and application in rice breeding of these BB resistance genes, and the future influence and direction of the remained research for rice BB resistance breeding are also prospected.

This review aims to describe the role of poly-ADP-ribose polymerase inhibitors (PARPi) in the treatment of metastatic castration-resistant prostate cancer (mCRPC), an aggressive and lethal form of the disease. The introduction of PARPi has led to improved prognosis, particularly in patients with at least one somatic or germline mutation in DNA damage repair genes such as BRCA1 or BRCA2. Several recent studies have shown that PARPi, used alone or in combination with abiraterone or enzalutamide, improve progression-free survival and overall survival in patients with mCRPC.

Alcohol use disorder (AUD) is characterized by pathological motivation to consume alcohol and cognitive inflexibility, leading to excessive alcohol seeking and use. In this study, we investigated the molecular correlates of impaired extinction of alcohol seeking during forced abstinence using a mouse model of AUD in the automated IntelliCage social system. This model distinguished AUD-prone and AUD-resistant animals based on the presence of ≥2 or <2 criteria of AUD, respectively.

Type I interferon (IFN-I) is highly prevalent in autoimmune disorders and is intricately involved in disease pathogenesis, including Sjögren's disease (SjD), also known as Sjögren's syndrome. Although the T follicular helper (Tfh) cell response has been shown to drive SjD development in a mouse model of experimental Sjögren's syndrome (ESS), the connection between IFN-I and the Tfh cell response remains unclear. As the activation of stimulator of interferon genes (STING) induces IFN-I production, we first demonstrated that mice deficient in STING or IFN-I signaling presented diminished Tfh cells and were completely resistant to ESS development.

Cholesterol biosynthesis is more activated in triple negative breast cancer (TNBC) than in other subtype breast cancer and plays essential role in facilitating TNBC. However, the regulatory network and how cholesterol biosynthesis contribute to TNBC development and progression are not well elucidated. Here, we found that reticulum membrane protein complex 2 (EMC2) is highly expressed in TNBC and predicts short survival of patients.

T-cell receptors (TCRs) recognize antigens derived from fragments of somatically expressed proteins that are degraded by the proteasome and presented by specific human leukocyte antigen (HLA) molecules. Recent therapeutic advances using the TCR as a tumor-targeting moiety have focused attention on loss of heterozygosity (LOH) as a potential resistance mechanism. Allele-specific LOH, rather than allele-agnostic, is particularly pertinent, but rarely evaluated.
