Summary: This study explores the transcriptional and metabolic regulations of FoxO3a in early placental development. It demonstrates that FoxO3a plays a crucial role in trophoblast migration and invasion by regulating COX-2, MMP9, aromatic amino acids, energy metabolism, and oxidative stress.

Summary: This study reveals that CHD1L is highly expressed in patients with essential hypertension (EH) and its interference can inhibit the proliferation, migration, invasion, and phenotypic switching of vascular smooth muscle cells (VSMCs). It also reduces inflammation and oxidative stress. Furthermore, it is found that FOXO3a suppresses the proliferation and migration of AngII-induced VSMCs by down-regulating CHD1L.

Summary: Tox4 protein is a regulator of PP1 phosphatases with unknown function in development. In mice, conditional knockout of Tox4 reduces thymic cellularity, partially blocks T cell development, and decreases the ratio of CD8 to CD4 cells. Tox4 loss also impairs proliferation of the fast-proliferating DP blast population within DP cells through downregulation of genes critical for proliferation, and genes with high and low expression level are more dependent on Tox4. Mechanistically, Tox4 may facilitate transcriptional reinitiation and restrict elongation in a dephosphorylation-dependent manner, and it is an evolutionarily conserved regulator of transcriptional elongation and reinitiation. Tox4 controls T cell development in mice by regulating transcription of cell cycle regulation genes via PP1 phosphatases, independent of chromatin accessibility modulation.

Summary: The study demonstrates the importance of PP2A in efficient replication of various IAV subtypes, as decreased PP2Ac levels result in reduced cell viability and increased cell death after IAV infection. This is attributed to a synergistic action of hyper-activated PI3K/Akt, MAPK/JAK-STAT, and NF-kB signaling pathways related to apoptosis, indicating the critical role of PP2A in orchestrating cell survival mechanisms during IAV infection.

Summary: The study found that Butea monosperma, a traditional Indian medicine, has potent anti-IL-6 activity and can be used for the treatment of ovarian cancer. It inhibits IL-6 signaling pathway, suppresses cell proliferation, migration, and invasion, induces cell cycle arrest and apoptosis, and significantly inhibits the growth of ovarian cancer.

Summary: Recent studies have shown that the hypothalamus plays a crucial role in aging by regulating NF-kappa B-directed GnRH decline. Activation of the PI3K/Akt/FoxO3a pathway can protect GnRH neurons from hypoxia-reoxygenation-induced decline, providing new insights into the regulatory mechanisms of hypothalamic GnRH decline associated with hypoxia-reoxygenation.

Summary: The study found an imbalance of the Treg/Th17 axis in PBC patients, with weakened Treg function being a potential reason for disease progression. The imbalance of the Treg/Th17 axis in PBC is likely influenced by FoxP3 hypermethylation, and treatment with DAC can suppress FoxP3 methylation to restore balance and alleviate liver lesions and inflammation in PBC.

Summary: The study found that the expression of SIRT3, FOXO3, and CDT1 was suppressed in lung cancer tissues and cells. Increasing SIRT3 levels can increase the expression of the FOXO3a/CDT1 axis, thereby enhancing the sensitivity of lung cancer cells.

Summary: Osteoimmunology highlights the complex interplay between bone and immune cells, with TCPTP playing a crucial role in regulating immune responses and bone metabolism. TCPTP negatively regulates macrophage activation and inflammatory factors secretion to inhibit bone resorption, while also modulating T lymphocytes and B lymphocytes to maintain bone homeostasis. This review provides valuable insights into the potential therapeutic targeting of TCPTP for inflammatory bone loss.

Summary: The focus of this study is FOXM1, which is identified as a potential therapeutic target for cancer immunotherapy and associated with the modulation of PD-L1 expression. The study found that selective knockdown of FOXM1 or treatment with TST significantly reduces PD-L1 expression in NSCLC cells and inhibits proliferation. Animal studies showed that TST treatment downregulates PD-L1 expression in NSCLC tumors and reduces tumor size without side effects. Combined treatment with TST and anti-4-1BB antibody induces synergistic therapeutic outcomes against immune resistant lung tumors and increases the number of CD3(+) T cells in tumor tissues.

Summary: FOXL2 and ESR2 play key transcriptional roles in ovarian granulosa cells, with FOXL2 activating genes enriched in H3K27ac marks and capable of activating transcription through binding to enhancer sites. Depletion of either Foxl2 or Esr2 in granulosa cells leads to decreased migration, invasion, and adhesion, potentially through modulation of common targets involved in cell motility.

Summary: Vascular barrier dysfunction, characterized by increased permeability and inflammation of endothelial cells, plays a crucial role in acute lung injury, ARDS, sepsis, and COVID-19. Ser/Thr protein phosphatases (PPases), including PP1 and PP2A, are important regulators of endothelial barrier integrity and cytoskeletal remodeling. Understanding the role of PPases in EC barrier regulation can provide insights into the development of therapeutic strategies for these lung diseases.
