Abstract
Since practically a century ago, the insulin pathway was discovered in both vertebrates and invertebrates, implying an evolutionarily ancient origin. After a century of research, it is now clear that the insulin signal transduction pathway is a critical, flexible and pleiotropic pathway, evolving into multiple anabolic functions besides glucose homeostasis. It regulates paramount aspects of organismal well-being like growth, longevity, intermediate metabolism, and reproduction. Part of this diversification has been attained by duplications and divergence of both ligands and receptors riding on a common general signal transduction system. One of the aspects that is strikingly different is its usage in reproduction, particularly in male versus female development and fertility within the same species. This review highlights sexual divergence in metabolism and reproductive tract differences, the occurrence of sexually "exaggerated" traits, and sex size differences that are due to the sexes' differential activity/response to the insulin signaling pathway.

Abstract
Circadian phenomena rule many activities of life on earth. Disruptions in circadian rhythmicity and rhythms have been recognized as a contributing factor for diseased states, for instance metabolic disruptions like diabetes. Diabetes develops as a consequence of faulty insulin pathway signaling, either by lack of insulin production (diabetes type I), or by loss of responsiveness in target tissues (diabetes type 2). In this work we use the model organism Drosophila melanogaster with three different mutant hypomorphic conditions at different levels of the insulin pathway. The insulin pathway is a very evolutionarily conserved pathway. We study these different diabetic conditions as a source of circadian rhythm abnormalities and circadian-related co-morbidities. We do so by studying circadian rhythmicity, activity, sleep and sleep structure, and feeding behavior. Results show that flies with impaired insulin signaling show circadian rhythm and rhythmic-related co-morbidities, especially female flies, as a consequence of the diabetic state. The most extreme disruptions occur in flies with impaired insulin receptor signaling, which stands at the beginning of the insulin pathway, in principle affecting most if not all aspects of this pathway. Our work shows that defective insulin signaling is a source of circadian rhythm and rhythmic related co-morbidities.

Abstract
Moringa is a common medicinal plant tree with mistletoe infestation and its leaf is widely used as food and traditional medication in alleviating several metabolic and neurodegenerative diseases. Hence, this study investigated the influence of African mistletoe on the antioxidant, antidiabetic, and neuroprotective activities of infested moringa leaf in sucrose induced diabetes in Drosophila melanogaster model. Glucose and triglycerides were evaluated in the flies' hemolymph and all other parameters were evaluated in the tissues. A significant (p < .05) decrease in survival rate and increase in the level of glucose and triglycerides in flies fed with 30% of sucrose when compared with control was obtained. Treated flies had significant (p < .05) positive alteration in the level of glucose, triglycerides, antioxidants (both enzymatic and nonenzymatic), and enzyme activities when compared with normal and sucrose control flies. This study suggests that mistletoe infestation did not alter the antioxidant, antidiabetic, and neuroprotective effects of the moringa leaf. PRACTICAL APPLICATIONS: This present study has shown that mistletoe infestation did not alter the protective activities of moringa leaf, hence, moringa with or without mistletoe infestation could be taken as functional food to mitigate several metabolic diseases.

Abstract
The formation, overgrowth and metastasis of tumors comprise a complex series of cellular and molecular events resulting from the combined effects of a variety of aberrant signaling pathways, mutations, and epigenetic alterations. Modeling this complexity in vivo requires multiple genes to be manipulated simultaneously, which is technically challenging. Here, we analyze how Drosophila research can further contribute to identifying pathways and elucidating mechanisms underlying novel cancer driver (risk) genes associated with tumor growth and metastasis in humans.

Abstract
The robust specification of organ development depends on coordinated cell-cell communication. This process requires signal integration among multiple pathways, relying on second messengers such as calcium ions. Calcium signaling encodes a significant portion of the cellular state by regulating transcription factors, enzymes, and cytoskeletal proteins. However, the relationships between the inputs specifying cell and organ development, calcium signaling dynamics, and final organ morphology are poorly understood. Here, we have designed a quantitative image-analysis pipeline for decoding organ-level calcium signaling. With this pipeline, we extracted spatiotemporal features of calcium signaling dynamics during the development of the Drosophila larval wing disc, a genetic model for organogenesis. We identified specific classes of wing phenotypes that resulted from calcium signaling pathway perturbations, including defects in gross morphology, vein differentiation, and overall size. We found four qualitative classes of calcium signaling activity. These classes can be ordered based on agonist stimulation strength Gαq-mediated signaling. In vivo calcium signaling dynamics depend on both receptor tyrosine kinase/phospholipase C γ and G protein-coupled receptor/phospholipase C β activities. We found that spatially patterned calcium dynamics correlate with known differential growth rates between anterior and posterior compartments. Integrated calcium signaling activity decreases with increasing tissue size, and it responds to morphogenetic perturbations that impact organ growth. Together, these findings define how calcium signaling dynamics integrate upstream inputs to mediate multiple response outputs in developing epithelial organs.

Abstract
Drosophila melanogaster has been used as a very versatile and potent model in the past few years for studies in metabolism and metabolic disorders, including diabetes types 1 and 2. Drosophila insulin signaling, despite having seven insulin-like peptides with partially redundant functions, is very similar to the human insulin pathway and has served to study many different aspects of diabetes and the diabetic state. Yet, very few studies have addressed the chronic nature of diabetes, key for understanding the full-blown disease, which most studies normally explore. One of the advantages of having Drosophila mutant viable combinations at different levels of the insulin pathway, with significantly reduced insulin pathway signaling, is that the abnormal metabolic state can be studied from the onset of the life cycle and followed throughout. In this review, we look at the chronic nature of impaired insulin signaling. We also compare these results to the results gleaned from vertebrate model studies.

Abstract
We review the use of a model organism to study the effects of a slow course, degenerative disease: namely, diabetes mellitus. Development and aging are biological phenomena entailing reproduction, growth, and differentiation, and then decline and progressive loss of functionality leading ultimately to failure and death. It occurs at all biological levels of organization, from molecular interactions to organismal well being and homeostasis. Yet very few models capable of addressing the different levels of complexity in these chronic, developmental phenomena are available to study, and model organisms are an exception and a welcome opportunity for these approaches. Genetic model organisms, like the common fruit fly, Drosophila melanogaster, offer the possibility of studying the panoply of life processes in normal and diseased states like diabetes mellitus, from a plethora of different perspectives. These long-term aspects are now beginning to be characterized.

Abstract
Flying insects are well known for airborne odour tracking and have evolved diverse chemoreceptors. While ionotropic receptors (IRs) are found across protostomes, insect odorant receptors (ORs) have only been identified in winged insects. We therefore hypothesized that the unique signal transduction of ORs offers an advantage for odour localization in flight. Using Drosophila, we found expression and increased activity of the intracellular signalling protein PKC in antennal sensilla following odour stimulation. Odour stimulation also enhanced phosphorylation of the OR co-receptor Orco in vitro, while site-directed mutation of Orco or mutations in PKC subtypes reduced the sensitivity and dynamic range of OR-expressing neurons in vivo, but not IR-expressing neurons. We ultimately show that these mutations reduce competence for odour localization of flies in flight. We conclude that intracellular regulation of OR sensitivity is necessary for efficient odour localization, which suggests a mechanistic advantage for the evolution of the OR complex in flying insects.

Abstract
Inositol phosphate kinase 2 (Ipk2), also known as IP multikinase IPMK, is an evolutionarily conserved protein that initiates production of inositol phosphate intracellular messengers (IPs), which are critical for regulating nuclear and cytoplasmic processes. Here we report that Ipk2 kinase activity is required for the development of the adult fruit fly epidermis. Ipk2 mutants show impaired development of their imaginal discs, the primordial tissues that form the adult epidermis. Although disk tissue seems to specify normally during early embryogenesis, loss of Ipk2 activity results in increased apoptosis and impairment of proliferation during larval and pupal development. The proliferation defect is in part attributed to a reduction in JAK/STAT signaling, possibly by controlling production or secretion of the pathway's activating ligand, Unpaired. Constitutive activation of the JAK/STAT pathway downstream of Unpaired partially rescues the disk growth defects in Ipk2 mutants. Thus, IP production is essential for proliferation of the imaginal discs, in part, by regulating JAK/STAT signaling. Our work demonstrates an essential role for Ipk2 in producing inositide messengers required for imaginal disk tissue maturation and subsequent formation of adult body structures and provides molecular insights to signaling pathways involved in tissue growth and stability during development.

Abstract
Diabetes mellitus is a disease with considerable morbidity and mortality worldwide. Breakdown of the blood-retinal barrier and leakage from the retinal vasculature leads to diabetic macular edema, an important cause of vision loss in patients with diabetes. Although epidemiologic studies and randomized clinical trials suggest that glycemic control plays a major role in the development of vascular complications of diabetes, insulin therapies for control of glucose metabolism cannot prevent long-term retinal complications. The phenomenon of temporary paradoxical worsening of diabetic macular edema after insulin treatment has been observed in a number of studies. In prospective studies on non-insulin-dependent (type 2) diabetes mellitus patients, a change in treatment from oral drugs to insulin was often associated with a significant increased risk of retinopathy progression and visual impairment. Although insulin therapies are critical for regulation of the metabolic disease, their role in the retina is controversial. In this study with diabetic mice, insulin treatment resulted in increased vascular leakage apparently mediated by betacellulin and signaling via the epidermal growth factor (EGF) receptor. In addition, treatment with EGF receptor inhibitors reduced retinal vascular leakage in diabetic mice on insulin. These findings provide unique insight into the role of insulin signaling in mediating retinal effects in diabetes and open new avenues for therapeutics to treat the retinal complications of diabetes mellitus.
