RNA plays important roles in the regulation of gene expression in response to environmental stimuli. , a long noncoding cis-natural antisense RNA, is a key component of regulating the response to cold temperature in . There are three mechanisms through which fine tunes the transcriptional response to cold temperatures. regulates the expression of the (C-Repeat Dehydration Binding Factor 1) transcription factor through a collisional transcription mechanism and a dsRNA and DICER mediated mechanism. also interacts with Polycomb Repressor Complex 2 to regulate the histone methylation of . Both and are key components of the ( regulon that direct the plant's response to cold temperature over time, as well as plant drought adaptation, pathogen responses, and growth regulation. The different isoforms of and its potential to form dynamic RNA conformations are important features in regulating a complex gene network in concert with several other noncoding RNA. This review will summarize the three mechanisms through which participates in gene regulation, describe the ways that dynamic RNA structures support the function of regulatory noncoding RNA, and explore the potential for improving agricultural genetic engineering with a better understanding of the roles of noncoding RNA.

Background: The consequences of natural disasters, such as damage to food systems, destruction of transport infrastructure, and organizational issues, can threaten the food security of people. Hence, food security measures are among the most important responses in the management of natural disasters. This study was conducted to identify the challenges in food security response following a great earthquake in Turkey.

Immune checkpoint blockade (ICB) therapy is a widely favored anti-tumor treatment, but it shows limited response to non-immunogenic "cold" tumors and suffers from drug resistance. Photodynamic therapy (PDT), as a powerful localized treatment approach, can convert a "cold tumor" into a "hot tumor" by inducing immunogenic cell death (ICD) in tumor cells, thereby enhancing tumor immunogenicity and promoting tumor immunotherapy. However, the effectiveness of PDT is largely hindered by the limited penetration depth into tumor tissues.

Jujube (Ziziphus ujuba Mill.) holds great importance as a fruit tree in China, with strong tolerance to drought and saline stress, but its growth is limited by vulnerability to cold stress. Consequently, the role of MAPK cascades in mediating jujube cold stress response remains unclear, with the specific function of ZjMAPKK4 in this context yet to be fully elucidated.

Aim: The objective of pulpotomy is to preserve the pulp vitality. However, the assessment of pulpal status following pulpotomy is often overlooked. This retrospective analysis aimed to compare the pulp responses to EPT (Electric pulp test) and cold test in mature permanent molars that have undergone either complete pulpotomy (CP) or partial pulpotomy (PP) for managing carious pulpal exposure and symptomatic irreversible pulpitis (SIP) and completed 12 months follow-up.

Middle-aged obesity, characterized by excessive fat accumulation and systemic energy imbalance, often precedes various health complications. Recent research has unveiled a surprising link between DNA damage response and energy metabolism. Here, we explore the role of Eepd1, a DNA repair enzyme, in regulating adipose tissue function and obesity onset.
