Diabetes mellitus, a complex metabolic disorder, continues to pose a significant global health challenge. Conventional approaches to diabetes management primarily focus on pharmacological interventions, often accompanied by adverse effects and limited long-term efficacy. In recent years, the exploration of natural compounds, particularly phytochemicals derived from plants, has garnered increasing attention for their potential role in diabetes management. This comprehensive review synthesizes the current understanding of the role of phytochemicals in anti-diabetic therapy. Phytochemicals, bioactive compounds abundant in various plant sources, exhibit diverse biological activities that can impact key mechanisms underlying diabetes. They interact with cellular pathways involved in glucose metabolism, insulin sensitivity, and oxidative stress, thereby offering potential therapeutic benefits. We delve into the intricate molecular mechanisms through which phytochemicals exert their anti-diabetic effects. Flavonoids, polyphenols, alkaloids, and other classes of phytochemicals are discussed in terms of their ability to modulate glucose uptake, enhance insulin signaling, and mitigate inflammation. Moreover, their antioxidant properties are explored in relation to ameliorating oxidative stress-associated complications observed in diabetes. The review also highlights the challenges associated with translating phytochemical research into practical anti-diabetic interventions. Bioavailability, dose determination, and standardized formulations emerge as critical considerations for clinical application. Furthermore, we underscore the significance of interdisciplinary collaborations between pharmacologists, clinicians, and botanists to bridge the gap between traditional knowledge and modern evidence-based medicine. &nbsp

Cell Permeable Ratiometric Fluorescent Sensors for Imaging Phosphoinositides

Phosphoinositides are critical cell-signal mediators present on the plasma membrane. The dynamic change of phosphoinositide concentrations on the membrane including clustering and declustering mediates signal transduction. The importance of phosphoinositides is scored by the fact that they participate in almost all cell-signaling events, and a defect in phosphoinositide metabolism is linked to multiple diseases including cancer, bipolar disorder, and type-2 diabetes. Optical sensors for visualizing phosphoinositide distribution can provide information on phosphoinositide dynamics. This exercise will ultimately afford a handle into understanding and manipulating cell-signaling processes. The major requirement in phosphoinositide sensor development is a selective, cell permeable probe that can quantify phosphoinositides. To address this requirement, we have developed short peptide-based ratiometric fluorescent sensors for imaging phosphoinositides. The sensors afford a selective response toward two crucial signaling phosphoinositides, phosphatidylinositol-4,5-bisphosphate (PI­(4,5)­P2) and phosphatidylinositol-4-phosphate (PI4P), over other anionic membrane phospholipids and soluble inositol phosphates. Dissociation constant values indicate up to 4 times higher probe affinity toward PI­(4,5)­P2 when compared to PI4P. Significantly, the sensors are readily cell-permeable and enter cells within 15 min of incubation as indicated by multiphoton excitation confocal microscopy. Furthermore, the sensors light up signaling phosphoinositides present both on the cell membrane and on organelle membranes near the perinuclear space, opening avenues for quantifying and monitoring phosphoinositide signaling

An early cortical progenitor-specific mechanism regulates thalamocortical innervation

The cortical subplate is critical in regulating the entry of thalamocortical sensory afferents into the cortex. These afferents reach the subplate at embryonic day (E)15.5 in the mouse, but "wait" for several days, entering the cortical plate postnatally. We report that when transcription factor LHX2 is lost in E11.5 cortical progenitors, which give rise to subplate neurons, thalamocortical afferents display premature, exuberant ingrowth into the E15.5 cortex. Embryonic mutant subplate neurons are correctly positioned below the cortical plate, but they display an altered transcriptome and immature electrophysiological properties during the waiting period. The sensory thalamus in these cortex-specific Lhx2 mutants displays atrophy and by postnatal day (P) 7, sensory innervation to the cortex is nearly eliminated leading to a loss of the somatosensory barrels. Strikingly, these phenotypes do not manifest if LHX2 is lost in postmitotic subplate neurons, and the transcriptomic dysregulation in the subplate resulting from postmitotic loss of LHX2 is vastly distinct from that seen when LHX2 is lost in progenitors. These results demonstrate a mechanism operating in subplate progenitors that has profound consequences on the growth of thalamocortical axons into the cortex. SIGNIFICANCE STATEMENT Thalamocortical nerves carry sensory information from the periphery to the cortex. When they first grow into the embryonic cortex, they "wait" at the subplate, a structure critical for the guidance and eventual connectivity of thalamic axons with their cortical targets. How the properties of subplate neurons are regulated is unclear. We report that transcription factor LHX2 is required in the progenitor "mother" cells of the cortical primordium when they are producing their "daughter" subplate neurons, in order for the thalamocortical pathway to wait at the subplate. Without LHX2 function in subplate progenitors, thalamocortical axons grow past the subplate, entering the cortical plate prematurely. This is followed by their eventual attrition and, consequently, a profound loss of sensory innervation of the mature cortex.</p
