Supplementary information

FOXO1A also known as forkhead box O1 FOXO1 or FOXO1 transcription factor is a protein with a molecular weight of approximately 70 kDa. It is an important transcription factor in the FOXO family responsible for regulating gene expression in response to environmental and physiological stimuli. FOXO1A predominantly localizes in the nucleus but can translocate to the cytoplasm under certain conditions. Expression of FOXO1A occurs in various tissues including liver adipose tissue and pancreatic islets indicating its broad functional roles in different organs.
Biological function summary

FOXO1A acts as a regulator of metabolic pathways apoptosis and cell cycle regulation. Its role in glucose metabolism stands out as a critical function where it influences insulin signaling and glucose homeostasis. FOXO1A can also form complexes with other transcription factors like PPARγ enhancing its regulatory capacity. Interactions within these complexes dictate the transcriptional outcomes influencing cellular responses to stress and growth signals.

Pathways

The FOXO1 transcription factor plays a critical role in the insulin signaling and PI3K-Akt pathway. These pathways are essential for maintaining energy balance and cellular survival. FOXO1A interacts with proteins like Akt which phosphorylates FOXO1A resulting in its cytoplasmic sequestration and subsequent inactivation. This regulation is vital for insulin-mediated glucose uptake and overall metabolic homeostasis preserving cellular functions under fluctuating nutrient conditions.

Aberrant FOXO1A activity is associated with type 2 diabetes and certain cancers. Dysregulation leads to impaired insulin signaling and glucose metabolism contributing to insulin resistance and hyperglycemia in diabetes. In cancer altered FOXO1A expression affects apoptosis and cell proliferation influencing tumor progression and survival. Associations with proteins such as Akt and PPARγ in these conditions further exemplify its network in disease mechanisms highlighting its potential as a therapeutic target.

Transcription factor that is the main target of insulin signaling and regulates metabolic homeostasis in response to oxidative stress (PubMed : 10358076, PubMed : 12228231, PubMed : 15220471, PubMed : 15890677, PubMed : 18356527, PubMed : 19221179, PubMed : 20543840, PubMed : 21245099). Binds to the insulin response element (IRE) with consensus sequence 5'-TT[G/A]TTTTG-3' and the related Daf-16 family binding element (DBE) with consensus sequence 5'-TT[G/A]TTTAC-3' (PubMed : 10358076). Activity suppressed by insulin (PubMed : 10358076). Main regulator of redox balance and osteoblast numbers and controls bone mass (By similarity). Orchestrates the endocrine function of the skeleton in regulating glucose metabolism (By similarity). Also acts as a key regulator of chondrogenic commitment of skeletal progenitor cells in response to lipid availability : when lipids levels are low, translocates to the nucleus and promotes expression of SOX9, which induces chondrogenic commitment and suppresses fatty acid oxidation (By similarity). Acts synergistically with ATF4 to suppress osteocalcin/BGLAP activity, increasing glucose levels and triggering glucose intolerance and insulin insensitivity (By similarity). Also suppresses the transcriptional activity of RUNX2, an upstream activator of osteocalcin/BGLAP (By similarity). Acts as an inhibitor of glucose sensing in pancreatic beta cells by acting as a transcription repressor and suppressing expression of PDX1 (By similarity). In hepatocytes, promotes gluconeogenesis by acting together with PPARGC1A and CEBPA to activate the expression of genes such as IGFBP1, G6PC1 and PCK1 (By similarity). Also promotes gluconeogenesis by directly promoting expression of PPARGC1A and G6PC1 (PubMed : 17024043). Important regulator of cell death acting downstream of CDK1, PKB/AKT1 and STK4/MST1 (PubMed : 18356527, PubMed : 19221179). Promotes neural cell death (PubMed : 18356527). Mediates insulin action on adipose tissue (By similarity). Regulates the expression of adipogenic genes such as PPARG during preadipocyte differentiation and, adipocyte size and adipose tissue-specific gene expression in response to excessive calorie intake (By similarity). Regulates the transcriptional activity of GADD45A and repair of nitric oxide-damaged DNA in beta-cells (By similarity). Required for the autophagic cell death induction in response to starvation or oxidative stress in a transcription-independent manner (PubMed : 20543840). Mediates the function of MLIP in cardiomyocytes hypertrophy and cardiac remodeling (By similarity). Positive regulator of apoptosis in cardiac smooth muscle cells as a result of its transcriptional activation of pro-apoptotic genes (PubMed : 19483080). Regulates endothelial cell (EC) viability and apoptosis in a PPIA/CYPA-dependent manner via transcription of CCL2 and BCL2L11 which are involved in EC chemotaxis and apoptosis (PubMed : 31063815).
