Molecular pathway of pancreatic cancer-associated neuropathic pain.

The pancreas is a heterocrine gland that has both exocrine and endocrine parts. Most pancreatic cancer begins in the cells that line the ducts of the pancreas and is called pancreatic ductal adenocarcinoma (PDAC). PDAC is the most encountered pancreatic cancer type. One of the most important characteristic features of PDAC is neuropathy which is primarily due to perineural invasion (PNI). PNI develops tumor microenvironment which includes overexpression of fibroblasts cells, macrophages, as well as angiogenesis which can be responsible for neuropathy pain. In tumor microenvironment inactive fibroblasts are converted into an active form that is cancer-associated fibroblasts (CAFs). Neurotrophins they also increase the level of Substance P, calcitonin gene-related peptide which is also involved in pain. Matrix metalloproteases are the zinc-associated proteases enzymes which activates proinflammatory interleukin-1ß into its activated form and are responsible for release and activation of Substance P which is responsible for neuropathic pain by transmitting pain signal via dorsal root ganglion. All the molecules and their role in being responsible for neuropathic pain are described below.

The influential responsibility of sirtuins in senescence and associated diseases: A review.

Aging is a process of time-associated depletion in the physiological functions, essential for the survival and reproducibility of living beings. Some age-related disorders can be successfully controlled with some biomedical techniques or pharmaceutical approaches. There are some precise remedies that demonstrate conspicuous promise in the preclinical and clinical setup of extending lifespan or enhancing health by altering natural senescence. The sirtuin family of proteins is one of the most favorable targets for antiaging strategies. Sirtuins were initially identified as transcription repressors in yeast, but today they are known to exist in bacteria and eukaryotes, as well as humans. The SIRT (1-7) family of proteins in humans is made up of seven members, each of which has either mono-ADP ribosyl transferase or deacetylase activity. Researchers suggest that sirtuins are essential for cell metabolism and play a major role in how cells react to various stimuli, such as oxidative or genotoxic stress. A healthy lifestyle, which includes exercise and a balanced diet, has been demonstrated to impact health span by adjusting the levels of sirtuins, suggesting the involvement of sirtuins in extending human longevity. The hunt for sirtuin activators is among the most extensive and comprehensive research subjects in the present scenario. Some optimism has been generated to investigate antiaging therapies by natural compounds, such as curcumin and others. This review article highlights the role of sirtuins in native senescence and their primordial roles in the progression of several life-threatening diseases. Further, it also provides recent information on the sirtuin activators and inhibitors and their therapeutic benefits.

Beneficial effect of 5-HT1b/1d agonist on Parkinson's disease by modulating glutamate and reducing deposition of α-synuclein.

The given investigation examined the neuroprotection role of 5-HT1b/1d agonist in reserpine induced Parkinson's disease (PD) in male Wistar rats. PD was induced in rats by reserpine at 5 mg/kg ip for 3 days and thereafter the rats were provided with the following treatments for 4 days, zolmitriptan (ZLM) group (30 mg/kg ip); STD group (levodopa + carbidopa, 200 + 5 mg/kg ip); ZLM + GA group (zolmitriptan, 30 mg/kg ip and glutamic acid, 1.5 mg/kg); ZLM + DX group (zolmitriptan, 30 mg/kg ip and dextromethorphan, 20 mg/kg ip). All the groups were then assessed for cognitive and motor functions at the end of the protocol. Moreover, oxidative stress parameters and histopathological changes were observed in rats of all treatment groups. Deposition of α-synuclein in the brain tissue was observed by silver staining. Data of this investigation revealed that motor and cognitive functions were improved in the ZLM-treated group compared with the negative control group, which was observed to be reversed in ZLM + GA group. Treatment with ZLM ameliorated oxidative stress and histopathological changes in the brain tissue of PD rats. Further, ZLM reduced the deposition of α-synuclein in PD rats, which reversed in ZLM + GA-treated group. This study concludes by stating that 5-HT1b/1d agonist can prevent neurodegeneration and reduce oxidative stress in PD rats. The probable underlying mechanism of such an effect of 5-HT1b/1d agonist could be by regulating the deposition of α-synuclein and reducing the expression of NMDA receptor.

Rhoifolin protects cecal ligation and puncture induced sepsis mice model by regulating inflammatory pathway.

Sepsis is a systemic infection affects several organs, which needs novel therapy for the management of it, thus protective effect of Rhoifolin was estimated against sepsis. Cecal ligation and puncture (CLP) method was used to induce sepsis and thereafter mice were treated with rhoifolin (20 and 40 mg/kg, i.p.) for one week. Food intake and survival rate was determined sepsis mice, moreover liver function test and cytokines was estimated in the serum of sepsis mice. In the lung tissue homogenate, oxidative stress parameters were determined, histopathological analysis was performed in liver and lung tissue of sepsis mice. Food intake and percentage of survival was improved in rhoifolin treated group than sham group. Level of liver function enzyme and cytokine was reduced significantly in the serum of rhoifolin treated sepsis mice. Treatment with rhoifolin ameliorates the altered oxidative stress parameters, and mRNA expression of Toll-like receptor 4 (TLR-4) in lung tissue of sepsis mice. Histopathological changes were also reverse in rhoifolin treated group than sham group of mice. In conclusion, result of report indicates Rhoifolin treatment reduces oxidative stress and inflammation in CLP induced sepsis mice, as it regulates TLR4/MyD88/NF-κB pathway.

Protective effect of vanillin on the management of cecal ligation and puncture induced sepsis rat model.

Present investigation evaluates the protective effect of vanillin against sepsis. Sepsis was induced by cecal ligation and puncture (CLP) in rat and vanillin was administered at dose of 100 and 200 mg/kg p.o. for five days after induction of sepsis. Effect of vanillin was observed on the percentage of survival, body weight and food intake were determined in CLP induced sepsis rats. Level of liver enzymes in the serum and organ weight was also observed in vanillin treated CLP induced rats. Moreover, histopathological changes were also observed in liver and lung tissue of hematoxylin and eosin (H&E) staining. There was significant improvement in bodyweight and food intake in vanillin treated group than negative control group after the sepsis induction. Moreover, vanillin improves the percentage of survival rate and reduces the level of liver enzymes and spleen weight in CLP induced sepsis rat. It also improves the level of glutathione (GSH) compared to negative control group. In conclusion, data of investigation reveals that vanillin ameliorates the survival rate and oxidative stress in CLP induced sepsis rat model.

A brief review of vitamin D as a potential target for the regulation of blood glucose and inflammation in diabetes-associated periodontitis.

Diabetes is a metabolic disorder associated with various complications, including periodontitis. The risk of periodontitis is increased in patients with diabetes, while vitamin D deficiency is associated with both diabetes and periodontitis. Thus, there is a need to identify the molecular effects of vitamin D on the regulation of inflammation and glucose in diabetes-associated periodontitis. The Web of Science, Scopus, and PubMed databases were searched for studies of the molecular effects of vitamin D. Molecular effects were reportedly mediated by salivary secretions, interactions of advanced glycation end products (AGEs) with receptors of AGEs (RAGEs), cytokines, and oxidative stress pathways linking diabetes with periodontitis. Vitamin D supplementation attenuates inflammation in diabetes-associated periodontitis by reducing the levels of inflammatory cytokines and numbers of immune cells; it also has antibacterial effects. Vitamin D reduces cytokine levels through regulation of the extracellular signal-related kinase 1/2 and Toll-like receptor 1/2 pathways, along with the suppression of interleukin expression. Glucose homeostasis is altered in diabetes either because of reduced insulin production or decreased insulin sensitivity. These vitamin D-related alterations of glucoregulatory factors may contribute to hyperglycaemia; hyperglycaemia may also lead to alterations of glucoregulatory factors. This review discusses the pathways involved in glucose regulation and effects of vitamin D supplementation on glucose regulation. Further studies are needed to characterise the effects of vitamin D on diabetes-associated periodontitis.

Pyrazoline analogues: Design, synthesis, and evaluation of anti-osteoporosis activity.

A series of pyrazoline compounds were synthesised and their osteogenic potential was explored. Out of fifteen, six compounds (3a, 4ac, 5aaa, 7, 8ab and 4aa) showed significant osteoblast differentiation in the range of 1 pM -1 µM concentrations. Amongst all, compound 4aa was identified as most active molecule which showed effective mineralisation of osteoblast cells and up regulates the osteogenic marker gene such as Bmp-2, Runx-2 and Type-1col at both transcriptional and translational level. Besides exhibiting potential osteogenic activity, 4aa also possess significant anti-apoptotic activity at 1 pM &100 pM concentration and increases the osteoblast survival in serum deprived conditions.

Epifriedelinol Ameliorates the Neuropathic Pain and Recovers the Function in Spinal Cord Injury by Downregulation of Neuronal Apoptosis and NMDA Receptor.

Spinal cord injury (SCI) is commonly associated with neuropathic pain, which affects large population. Thus, the presented investigation evaluates the beneficial effect of epifriedelinol against SCI-associated neuropathic pain. SCI injury was induced in rats by clip-compression and rats were treated with epifriedelinol 100 and 200 mg/kg, i.p. for 21 days after the induction of SCI. The effect of epifriedelinol was assessed on neuropathic pain by mechanical allodynia and locomotor function. Level of inflammatory cytokines were assessed in the neuronal tissue using enzyme linked immunosorbent assay (ELISA) and expression of caspase-3 and Bcl2 protein were assessed by western blot assay. Data of investigation reveals that epifriedelinol reduces mechanical allodynia in SCI injured rats. Moreover, it also improves locomotor function in SCI injured rats. There was significant decrease in level of interleukin (IL)-1ß, IL-6 and tumor necrosis factor (TNF)-α in the neuronal tissues of epifriedelinol-treated group than negative control group. Moreover, treatment with epifriedelinol ameliorates the altered expression of caspase 3, Bcl2 and GluN1 and level of glutamate in neuronal tissue of SCI-injured rats. In conclusion, data reveal that epifriedelinol treatment protects neuropathic pain associated with spinal cord injury by downregulating the N-methyl-D-aspartate (NMDA) receptor function.

Phenanthrenoid Coelogin Isolated from Coelogyne cristata Exerts Osteoprotective Effect Through MAPK-Mitogen-Activated Protein Kinase Signaling Pathway.

Osteoporosis is a major health problem in postmenopausal women globally. This study determined the mechanism through which coelogin stimulates osteoblastogenesis and its osteoprotective and bone regenerating potential. Coelogin effect on primary calvarial osteoblast cells was determined by measuring alkaline phosphatase activity, mineralization, osteoblast survival, and apoptosis and protein expression studies. The osteoprotective effect of coelogin was also evaluated on osteopenic adult female Swiss mice. At autopsy, bones were collected for dynamic and histomorphometry studies. Serum samples were also collected for assessment of serum parameters. Coelogin treatment led to increased osteoblast proliferation, survival, differentiation, and mineralization in osteoblast cells. Coelogin supplementation to Ovx mice promoted new bone formation, prevented Ovx-induced deterioration of bone microarchitecture, and enhanced bone regeneration. In addition, signaling studies revealed that coelogin treatment activates the ER-Erk and Akt-dependent signaling pathways which stimulate the osteoblastogenesis in osteoblast cells.

A phenomenological scheme for reversed quartet mechanism of electron spin polarization in covalently linked systems of chromophore and free radical: Determination of magnitude of polarization and application to pyrene-TEMPO linked molecules.

Generation of electron spin polarization (ESP) during the bimolecular quenching of an excited chromophore by a free radical is generally explained by the radical-triplet pair mechanism, which is capable of giving the magnitudes of ESP arising from the quenching of the singlet or the triplet excited chromophore. When the chromophore and the free radical are covalently linked, although there are several mechanisms to explain the observed spin-polarized electron paramagnetic resonance signals under a variety of experimental conditions and in different chromophore-radical systems, there are no schemes that allow quantitative determination of the magnitude of ESP. In this work, we present a phenomenological scheme with this objective. In this scheme, we have incorporated several concepts of the reversed quartet mechanism of Rozenshtein et al. [J. Phys. Chem. A 109, 11144 (2005)] to our phenomenological sequential quenching scheme [V. Rane and R. Das, J. Phys. Chem. A 119, 5515 (2015)] of ESP in covalently linked chromophore-radical systems. This phenomenological reversed quartet scheme is able to explain the observed inversion of ESP with time and can also give a quantitative measure of the absorptive and emissive ESP in such systems. We have applied this scheme to the photophysical quenching of a series of newly synthesized pyrene-TEMPO molecules, where a spacer group of different lengths covalently links the pyrene chromophore and the TEMPO free radical. Given the simplicity of our scheme, reasonable estimates of the magnitudes of the ESP have been obtained in all cases.

In situ analytical techniques for battery interface analysis.

Lithium-ion batteries, simply known as lithium batteries, are distinct among high energy density charge-storage devices. The power delivery of batteries depends upon the electrochemical performances and the stability of the electrode, electrolytes and their interface. Interfacial phenomena of the electrode/electrolyte involve lithium dendrite formation, electrolyte degradation and gas evolution, and a semi-solid protective layer formation at the electrode-electrolyte interface, also known as the solid-electrolyte interface (SEI). The SEI protects electrodes from further exfoliation or corrosion and suppresses lithium dendrite formation, which are crucial needs for enhancing the cell performance. This review covers the compositional, structural and morphological aspects of SEI, both artificially and naturally formed, and metallic dendrites using in situ/in operando cells and various in situ analytical tools. Critical challenges and the historical legacy in the development of in situ/in operando electrochemical cells with some reports on state-of-the-art progress are particularly highlighted. The present compilation pinpoints the emerging research opportunities in advancing this field and concludes on the future directions and strategies for in situ/in operando analysis.

A Fluorescence Study on Binding Interaction of N-acetylated Dansylamide Conjugates with ß-cyclodextrin, Tween-20 and DPPC Lipid Bilayer Membrane.

The present work describes the photophysical behavior of a saturated fatty acid (palmitic acid) containing N-acetylated dansylamide derivative (DAN-PA) into biologically important organized assembly such as ß-cyclodextrin (ß-CD), Tween-20 (T-20) and 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) lipid bilayer membrane. The results were compared by using another N-acetylated dansylamide conjugate having a short hydrophobic tail, DAN-ACYL. Long hydrophobic tail (saturated fatty acid) containing dansylamide conjugate (DAN-PA) shows more efficient binding interactions with the ß-CD as compared to the short tail containing dansylamide derivative (DAN-ACYL). The calculated binding constants values of DAN-PA and DAN-ACYL probes are 1.35 × 102 M -1 and 0.31 × 102 M -1 respectively. The DAP-PA is a sensitive fluorophore for understanding the micellization process in T-20, as compared to the DAN-ACYL because it shows a significant change in fluorescent properties (steady-state and time-resolved both) with changing in T-20 concentrations. The calculated CMC value for T-20 surfactant is 0.07 mM. While the DAN-ACYL does not show any change in the fluorescent properties while changing the T-20 concentrations. Fluorescent parameters like steady-state and time-resolved of DAN-PA are quite sensitive towards the thermo-tropic phase transitional changes into lipid bilayer membrane properties. And the calculated thermo-tropic phase transition temperature by using DAN-PA fluorophore is 42 °C.

Distance-dependent formation of electronic charge-transfer states in the ground states of anthracene and pyrene covalently linked to a TEMPO free radical.

Charge-transfer (CT) electronic states are generally seen in molecules involving interactions between species of low ionization potential and high electron affinity. In this context, the 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO) free radical is not considered to be a typical molecule to form charge transfer states with aromatic hydrocarbons. Nevertheless, involvement of such CT states has been invoked in rationalising the spin-dependent photophysical quenching of excited states of aromatic systems by TEMPO during bimolecular collisions. Direct observation of such CT states, however, has been elusive until recently, with our first report on the observation of CT states involving naphthalene and TEMPO moieties covalently linked through a spacer group (Rane et al., J. Fluoresc., 2015, 25, 1351-1361). With a view to demonstrating more systems of CT states involving a TEMPO donor, and establishing a possible dependence on its distance from an acceptor chromophore, we have now extended our investigation to anthracene (An) and pyrene (Py) moieties linked to TEMPO, using two different spacer groups of different lengths. The molecules are An-CH2-O-TEMPO, Py-CH2-O-TEMPO, Py-(CH2)2-O-TEMPO, Py-(CH2)4-O-TEMPO, Py-CH2-CO-O-TEMPO and Py-(CH2)3-CO-O-TEMPO, where a linear alkyl chain containing an ether or an ester moiety constitutes the spacer group. We established the formation of CT states in their ground states by comparing their electronic absorption spectra, steady-state fluorescence spectra and time-resolved fluorescence signals with those of the parent molecules An-CH2-OH, Py-CH2-OH and Py-CH2-COOH. CT bands of appreciable intensity were seen only with An-CH2-O-TEMPO, Py-CH2-O-TEMPO and Py-CH2-CO-O-TEMPO, the molecules with the shortest spacer group. Approximate shapes of the absorption and emission bands of the CT states have been determined. For the rest, very weak bands were seen. Similar trends were seen in their fluorescence lifetimes also. Absorption intensities of the CT bands were found to decrease exponentially with the length of the spacer group. The presence of the ether or the ester moiety in the spacer groups showed little influence on the intensities of the CT bands. Our results are probably the first experimental demonstration of the expected exponential dependence of the efficiency of the formation of CT states on the length of the spacer groups of chromophore-TEMPO linked molecules.

Piracetam Attenuates LPS-Induced Neuroinflammation and Cognitive Impairment in Rats.

The present study was performed to investigate the effect of piracetam on neuroinflammation induced by lipopolysaccharide (LPS) and resulting changes in cognitive behavior. Neuroinflammation was induced by a single dose of LPS solution infused into each of the lateral cerebral ventricles in concentrations of 1 µg/µl, at a rate of 1 µl/min over a 5-min period, with a 5-min waiting period between the two infusions. Piracetam in doses of 50, 100, and 200 mg/kg i.p. was administered 30 min before LPS infusion and continued for 9 days. On ninth day, the behavioral test for memory and anxiety was done followed by blood collection and microdissection of the hippocampus (HIP) and prefrontal cortex brain regions. Piracetam attenuated the LPS-induced decrease in coping strategy to novel environment indicating anxiolytic activity. It also reversed the LPS-induced changes in the known arm and novel arm entries in the Y-maze test indicating amelioration of spatial memory impairment. Further, piracetam moderated LPS-induced decrease in the mitochondrial complex enzyme activities (I, II, IV, and V) and mitochondrial membrane potential. It ameliorated changes in hippocampal lipid peroxidation and nitrite levels including the activity of superoxide dismutase. Piracetam region specifically ameliorated LPS-induced increase in the level of IL-6 in HIP indicating anti-neuroinflammatory effect. Further, piracetam reduced HIP Aß (1-40) and increased blood Aß level suggesting efflux of Aß from HIP to blood. Therefore, the present study indicates preclinical evidence for the use of piracetam in the treatment of neuroinflammatory disorders.

Assessment of Levels of Glycosylated Hemoglobin in Patients with Periodontal Pathologies: A Comparative Study.

INTRODUCTION: One of the potential sources for the occurrence of various systemic pathologies, such as cardiovascular diseases, cerebrovascular diseases, and respiratory diseases is periodontitis. Testing of glycosylated hemoglobin (HbA) is a highly standardized procedure and is becoming increasingly popular these days due to its cost-effectiveness and ease of use. Literature quotes numerous studies associating the peri-odontal diseases with various hemoglobin markers in diabetic and nondiabetic patients. Hence, we planned the present study to assess the levels of HbA in patients with periodontitis among nondiabetic patients. MATERIALS AND METHODS: For the present study, a total of 50 nondiabetic subjects who reported to the department with the chief complaint of periodontitis were included. Another set of 50 nondiabetic individuals were included in the present study of comparable age in whom no periodontitis was detected clinically. Clinical examination and radiographic evaluation was performed for the selection of the cases for the study group. The patients were sent to the laboratory after the clinical examination, for the testing of HbA. Testing of the hemoglobin A1c (HbA1c) levels of all the subjects and controls was performed and values were noted and evaluated. RESULTS: Nonsignificant results were obtained while comparing the mean HbA1c concentrations among the study group and the control group. Nonsignificant results were obtained while comparing the mean HbA1c levels among males and females. While comparing the mean HbA1c levels between the study group and the control group divided on the basis of body mass index, nonsignificant results were obtained. CONCLUSION: In nondiabetic subjects, no significant correlation could be observed between periodontitis and HbA1c levels. CLINICAL SIGNIFICANCE: The HbA1c cannot be used as a reliable maker for differentiation of patients with periodontal pathologies from patients free of periodontal pathologies.

Synergistic protective effect of picrorhiza with honey in acetaminophen induced hepatic injury.

Rhizome of picrorhiza along with honey prevents hepatic damage and cure the acetaminophen (paracetamol) induced hepatotoxicity by modulating the activity of hepatic enzymes. Here, we studied the in vivo effects of Picrorhiza kurroa and honey on acetaminophen induced hepatotoxicity Balb/c mice model. Hepatic histopathological observations of acetaminophen fed (day-6) group showed more congestion, hemorrhage, necrosis, distorted hepatic architecture and nuclear inclusion. Such damages were recompensed to normal by picrorhiza or honey alone or both in combinations. We observed increased activity of SGPT and SGOT in injured liver tissues, and that too was compensated to normal with picrorhiza or honey alone or both in combinations. We observed 1.27 and 1.23-fold enhanced activity of SGPT in serum and liver lysate, respectively while SGOT showed 1.66 and 1.11 fold enhanced activity. These two enzymes are signature enzymes of liver damage. Thus, our results support that honey may be used with drug picrorhiza due to its synergistic role to enhance hepatoprotective and hepatoregenerative ability along with allopathic drugs to mitigate the hepatotoxic effects.

Fluorescence of N-acylated dansylamide with a long hydrophobic tail: sensitive response to premicellar aggregation of sodium deoxycholate.

The present work describes the synthesis and photophysical studies of two fluorescent dansylamide derivatives, in which the amine group is acylated by a long hydrophobic chain (a part of a biologically relevant palmitic acid) and by a short hydrophobic tail (a part of acetic acid). The long chain tethered dansyl analogue is successfully utilized in estimating critical micellar concentration (CMC) of bile salts (NaDC, NaC) as well as anionic and cationic surfactants (SDS, CTAB) with the help of enhanced fluorescence intensity facilitated by better solubilization of the molecule in microheterogeneous media. The long chain tethered dansylamide derivative shows significant fluorescence solvatochromism with a red shift (ca. 4000 cm(-1)) from hexane to water. In contrast, the solvatochromism exhibited by the parent/short acyl chain analogue is much less (ca. 2230 cm(-1) from hexane to water) and the fluorescence is not sensitive to micellization. Interestingly, the long chain tethered fluorescent probe shows high sensitivity towards premicellar aggregation of sodium deoxycholate (NaDC) bile salt, through a clear blue shift of emission maxima and concomitant enhancement of fluorescent intensity. Such an observation of fluorescence sensing of premicellar aggregation is unusual.

Amorphophallus campanulatus tuber extract protects diabetic nephropathy in streptozotocin-induced diabetic nephropathy rat model by regulating oxidative stress and TNF-α inflammatory pathway.

PURPOSE: To assess the effect of Amorphophallus campanulatus tuber (Ac) extract in the protection of diabetic nephropathy in streptozotocin (STZ) induced diabetic nephropathy (DN) rat model. METHODS: Diabetes was induced with STZ (60 mg/kg, i.p.), and DN was confirmed after six weeks of STZ administration with the estimation of kidney function test. Further rats were treated with Ac 250 and 500 mg/kg p.o. for next four week. Oxidative stress and level of inflammatory cytokines were estimated in the kidney tissue of DN rats. Histopathology of kidney tissue was performed using hematoxylin and eosin staining. RESULTS: There was improvement in the body weight of Ac treated groups than DN group of rats. Blood glucose level was observed to be reduced in Ac treated groups than DN group on 42nd and 70th day of protocol. Treatment with Ac ameliorated the altered level of kidney function tests (creatinine and BUN), enzymes of liver function (aspartate aminotransferase and alanine aminotransferase), and lipid profile in the serum of DN rats. Oxidative stress parameters (malondialdehyde and reactive oxygen species enhances and reduction in the level of glutathione and superoxide dismutase) and inflammatory cytokines such as interleukin-6, tumour necrosis factor-α, and monocyte chemoattractant protein-1 reduces in the tissue of Ac treated group than DN group. Treatment with Ac also attenuates the altered histopathological changes in the kidney tissue of DN rats. CONCLUSIONS: The report suggests that Ac protects renal injury in DN rats by regulating inflammatory cytokines and oxidative stress.

Molecular targets for management of diabetes: Remodelling of white adipose to brown adipose tissue.

Diabetes mellitus is a disorder characterised metabolic dysfunction that results in elevated glucose level in the bloodstream. Diabetes is of two types, type1 and type 2 diabetes. Obesity is considered as one of the major reasons intended for incidence of diabetes hence it turns out to be essential to study about the adipose tissue which is responsible for fat storage in body. Adipose tissues play significant role in maintaining the balance between energy stabilization and homeostasis. The three forms of adipose tissue are - White adipose tissue (WAT), Brown adipose tissue (BAT) and Beige adipose tissue (intermediate form). The amount of BAT gets reduced, and WAT starts to increase with the age. WAT when exposed to certain stimuli gets converted to BAT by the help of certain transcriptional regulators. The browning of WAT has been a matter of study to treat the metabolic disorders and to initiate the expenditure of energy. The three main regulators responsible for the browning of WAT are PRDM16, PPARγ and PGC-1α via various cellular and molecular mechanism. Presented review article includes the detailed elaborative aspect of genes and proteins involved in conversion of WAT to BAT.
