Summary: Bmp and Fgf signaling are involved in embryonic development, and their modulation of microRNAs plays a crucial role in regulating cell fate during cardiomyogenesis and PE/ST development. However, the role of Bmp and Fgf signaling in mouse PE/ST development is different from that in chicken, and their impact on cardiomyogenesis and fibrogenesis is limited. Species-specific differences in regulating PE/ST cardiomyogenic lineage commitment are supported by the data.

Summary: Plant cell walls are crucial for plant growth and adaptation to environmental stresses. Plants have evolved signaling mechanisms to maintain cell wall integrity, which can be activated by environmental and developmental signals. While the signaling pathways associated with environmental stress have been well studied, less attention has been given to cell wall integrity signaling in relation to normal plant growth and development. This review focuses on the role of cell wall integrity signaling in fruit ripening, including the signaling pathways involved in cell wall fragment, calcium, and NO signaling, as well as the involvement of Receptor-Like Protein Kinases (RLKs), specifically FERONIA and THESEUS, in hormone signal regulation during fruit development and ripening.

Summary: Conditions altering the yeast cell wall lead to the activation of an adaptive transcriptional response mainly governed by the cell wall integrity (CWI) mitogen-activated protein kinase (MAPK) pathway. Two high-throughput screenings were conducted to identify genes related to cell wall integrity and transcriptional program elicited by cell wall stress. Functional groups related to chromatin organization, Golgi vesicle transport, rRNA processing, and protein glycosylation were found to be highly representative. Additionally, genes associated with RNA metabolism, transcription/translation, protein degradation, and chromatin organization were highlighted.

Summary: Loss of FGF signaling leads to defects in salivary gland branching. Disruption of Fgfr1 and Fgfr2 expression in salivary gland epithelial cells reveals their coordinated function in regulating branching. Non-canonical FGF signaling mechanisms involving cell-cell and cell-matrix adhesion play a role in salivary gland branching morphogenesis.

Summary: Asthma is a difficult-to-cure disease and there is an urgent need for more reliable and effective medications. Acteoside, a phenylpropanoid glycoside found in various herbs, has been shown to have anti-inflammatory and antioxidant properties. However, there have been few studies on the impact of acteoside on asthma. Therefore, this study aimed to investigate the protective effects of acteoside on asthma and explore the underlying mechanisms both in vivo and in vitro.

Summary: The authors found that the pool of non-phosphorylated p38 MAPK can modulate signaling to control growth, lysosome formation, and neuronal integrity. By altering the stoichiometry of non-phospho-p38, they enhanced PMK-1 signaling to promote tissue integrity and longevity. Their findings suggest that reducing the reservoir of non-phospho-p38 can enhance signaling without hyper-activation of stress response during aging.

Summary: Vascular endothelial cells are influenced by mechanical forces and the patterns of these forces can regulate endothelial cell function and cardiovascular health. The transcription factor KLF2 plays a key role in the positive effects of laminar flow patterns on endothelial cell phenotype. Identifying endothelial regulators of the KLF2 program could lead to new therapeutic approaches for treating cardiovascular disease. GPCR targets that modulate KLF2 expression were identified through genetic screening, and several GPCRs were found to affect KLF2 transcriptional activation. These targets could be potential candidates for novel treatments targeting the endothelium. Initiating drug discovery efforts for LGR4 and finding synthetic ligands for this receptor demonstrate the potential for identifying new drug targets through pathway-directed phenotypic screening.

Summary: Developmental outcomes in plants are shaped by the interplay between intrinsic and external factors, with light playing a key role in promoting stomatal development. The study by Wang et al. reveals that the light-regulated transcription factor HY5 activates the expression of STOMAGEN, a mesophyll-derived secreted peptide that stabilizes the master regulator of stomatal development in the epidermis, leading to enhanced stomatal production. This work highlights a molecular link between light signaling and stomatal development across different tissue layers.

Summary: This study reveals the essential role of VE-cadherin in the development and maintenance of cardiac lymphatics and its impact on lymphangiogenic signaling pathways. Surprisingly, despite the regression of cardiac lymphatics, Cdh5(flox/flox);Prox1CreER(T2) mice exhibited preserved cardiac function at baseline and after myocardial infarction compared with control mice. Mechanistically, loss of VE-cadherin leads to aberrant cellular internalization of VEGFR3, impairing downstream processes such as cellular proliferation.

Summary: The tracheal epithelium is a crucial element in pulmonary diseases, and its understanding of cell proliferation and differentiation is limited. The Hedgehog (HH) signaling pathway plays a role in communication between epithelial and mesenchymal cells in the lung, affecting stromal cell proliferation, differentiation, and epithelial signaling. This study discovered an autocrine HH signaling function in airway epithelial cells, with its inhibition leading to defects in cell proliferation and differentiation. Additionally, HH function is mediated by transcriptional activation, as inhibition of HH signaling downregulates cell type-specific transcription factor genes in both mouse trachea and human airway epithelial cells. These findings provide new insights into the role of HH signaling in epithelial cell proliferation and differentiation during airway development.

Summary: The epicardium, the outermost layer of the heart, plays an important role in regulating cardiac regeneration. This study investigated the interaction between the epicardium and myocardium during development by creating three models of epicardial impairment in zebrafish. The results showed that the epicardium is required for cardiomyocyte growth during early cardiac morphogenesis and identified FGF and VEGF signaling pathways as important regulators of ventricular growth.

Summary: Tumor-associated macrophages (TAMs), including antitumor M1-like TAMs and protumor M2-like TAMs, play diverse roles in lung cancer development. It has been found that the spatial proximity of HDAC2-overexpressing M2-like TAMs to tumor cells is significantly correlated with poor overall survival of lung cancer patients. Suppression of HDAC2 in TAMs alters macrophage phenotype, migration, and signaling pathways related to interleukins, chemokines, cytokines, and T-cell activation.

Summary: Long noncoding RNAs (lncRNAs) play a role in gene transcription in many cells, but their function in tumor-associated macrophages (TAMs) is not well understood. The lncRNA ADPGK-AS1 is upregulated in M2-like human macrophages, macrophages exposed to lung cancer cells, and TAMs from human lung cancer tissue. Overexpression of ADPGK-AS1 promotes an M2-like, tumor-promoting phenotype in macrophages, while its knockdown induces an M1-like, tumor-suppressive phenotype, inhibiting lung tumor growth.

Summary: Transcriptional adaptation (TA) is a mechanism that modulates gene expression in response to mutations in mRNA. Researchers found a 25-base pair element in the regulatory region of the adapting gene that showed similarity to a sequence in the mutant mRNA. This element can induce ectopic expression of a fluorescent reporter gene, indicating its importance in TA.

Summary: Hepatic cysts are fluid-filled lesions in the liver that occur in about 5% of the population. Previous studies have shown that hepatic cyst formation is associated with increased proliferation and fluid secretion in cholangiocytes, partly due to impaired primary cilia. This study used a zebrafish mutant to investigate the underlying mechanisms of hepatic cysts and found that the cyst formation was caused by defects in biliary cell motility and protrusive activity. Whole-genome sequencing revealed a mutation in the furinb gene, which caused endoplasmic reticulum (ER) stress and contributed to the cystic phenotype. Inhibition of ER stress and mammalian target of rapamycin (mTOR) signaling reduced cyst formation. This study establishes a vertebrate model for studying hepatic cystogenesis and highlights the role of ER stress in the disease pathogenesis.
