Whole saliva is contains major, minor and gingival crevicular fluid/secretions and it plays vital role in maintaining the oral health, three pair of major salivary glands consist of parotid, submandibular and sub-lingual glands. Saliva is a good biological fluid to explore health and disease status of human. Further, the saliva secrets from major salivary glands and have various biomolecules such as, proteins, enzymes and ions originated from serum and saliva is easily accessible through a safe and noninvasive method. In contrast, the concentrations of biomolecules in saliva are generally one tenth to one thousand of the levels in blood. Ovulation is an exclusive process through the mature (pre-ovulatory) ovarian follicles reacts to the surge of luteinizing hormone (LH) and burst to discharge fertilizable oocytes. The LH surge initiates a flow of proteolytic actions with the aim of control ovulation. Presently, many salivary proteins are have been showed as a biomarker such as Sjogren’s syndrome, Lung cancer, oral and Systemic diseases, HIV-seropositive patients, dental pellicle development, and hyperglycemia. However, there is no prominent marker protein was reported for monitoring ovulation process in human saliva. It is important prediction of fertile period in women for various applications like assisted reproduction and invitro fertilization.

The salivary proteome profile in women throughout the menstrual cycle characterized by HR-LC-MS/MS |
Dr Govindaraju Archunan |
Generally saliva consists of mixture of proteins electrolytes and small organic compounds. This whole saliva stands for secretions from major (submandibular, sublingual and parotid) and minor salivary glands, along with crevicular fluid, bacteria and cellular debris. The secretion of saliva is regulated under the autonomic nervous system via signal transduction...
Generally saliva consists of mixture of proteins electrolytes and small organic compounds. This whole saliva stands for secretions from major (submandibular, sublingual and parotid) and minor salivary glands, along with crevicular fluid, bacteria and cellular debris. The secretion of saliva is regulated under the autonomic nervous system via signal transduction systems that couple receptor stimulation to ion transport and protein secretory mechanisms (Dodds, Johnson, & Yeh, 2005). SDS-PAGE is a unidimensional method used to analyze the molecular weights and charges of proteins by separating the proteins into bands, thereby making them visible. The most common use of gel electrophoresis is the qualitative analysis of the complex mixtures of proteins. Schwartz et al. proposed polyacrylamide gel electrophoresis (SDS-PAGE) as an adequate method to evaluate protein content in the human saliva. In this work it was aimed to study the saliva protein composition from different subjects by high resolution liquid chromatography mass spectrometry (HR-LC-MS/MS) on different days, throughout the menstrual cycle and the influence of ovulation.

Salivary proteins in buffalo with special emphasis to estrous cycle |
Dr Govindaraju Archunan |
Saliva is considered as the best source for biomarker-discovery studies, since it is a non-invasive method when compared to other body sources.

Saliva is considered as the best source for biomarker-discovery studies, since it is a non-invasive method when compared to other body sources. Usually, buffalo cannot express their estrus signs precisely. Hence, there is a need for concise methods to detect the time of estrus to ensure the success in artificial insemination. Therefore, we have established a reference proteome map on buffalo whole saliva during estrous cycle in order to document the estrus-specific proteins using SDS-PAGE and mass spectrometry. The present findings conclude that the proteomic approach adopted to identify the proteins from buffalo saliva around estrous cycle may provide a new tool for screening the estrus phase.

Assessment of host hemoglobin accumulation in P. berghei heme pathway ferrochelatase knockout parasite food vacuole by iTRAQ |
Dr Arun Nagaraj |
Two independent sets of fourplex iTRAQ labelling were carried out to assess the accumulation of host Hb in PbFCKO FVs. The results obtained have suggested that there is a ~3-4 -fold increase in Hb ï¡ and ï¢ chains in FCKO FVs as quantified by iTRAQ.

Food vacuole proteome of P. berghei heme pathway ferrochelatase knockout parasite by LC-MS/MS |

LC-MS/MS of in-solution trypsin digested FV protein extracts was carried out for the FVs isolated from PbWT and PbFCKO parasites. The FV preparations had signature FV proteins such as plasmepsin IV, berghepain, aminopeptidases, subunits of vacuolar-type H+ATPase (V-type H ATPase), together with parasitophorous vacuolar (PV) proteins including exported protein 1...
LC-MS/MS of in-solution trypsin digested FV protein extracts was carried out for the FVs isolated from PbWT and PbFCKO parasites. The FV preparations had signature FV proteins such as plasmepsin IV, berghepain, aminopeptidases, subunits of vacuolar-type H+ATPase (V-type H ATPase), together with parasitophorous vacuolar (PV) proteins including exported protein 1 (Exp1), Exp2, early transcribed membrane protein, PV1, PV5 (lipocalin) etc., and Rab GTPases associated with cytostome-FV trafficking. A total number of 251 and 201 proteins could be identified for WT (P1) and FCKO (P2) FVs, respectively, and 175 proteins were common between them suggesting an overall consistency in the preparations. The results obtained have suggested that the FV proteome in FCKO parasites is compromised. None of the subunits of V-type H+ATPase - a proton pump maintaining the acidic pH of FV could be detected in FCKO FVs indicating the lower abundance of these proteins. In addition, berghepain-2 - a cysteine protease involved in Hb degradation could not be detected in FCKO FVs.

LC-MS/MS of in-solution trypsin digested parasite protein extracts was carried out to examine the proteome of MSO-treated Pf parasites. Proteins were extracted from the untreated and MSO-treated parasite pellets of two independent experiments (Exp1: T7_R Vs T8; Exp2: T3_R Vs T4_R). For each experiment, two different sets of untreated and MSO-treated cultures synchronized for ring stages and early trophozoites were used. MSO treatment was carried out at 50 ïM concentration for 12 h. A total number of 149 proteins associated with various metabolic and cellular functions, cytoadherence and host invasion, Hb degradation, etc., were downregulated in MSO-treated parasites. This also included important asparagine-rich proteins such as tRNA ligases, components of RNA processing and protein degradation pathways, lipocalin associated with hemozoin formation and antimalarial drug sensitivity, heat shock protein 110c essential for stabilizing the asparagine repeat-rich parasite proteins etc. Only ten proteins were found to be upregulated in MSO-treated Pf3D7 parasites. For downregulated proteins, proteins identified in both the untreated controls of two independent experiments and either undetectable or significantly downregulated (>1.5 fold) in MSO-treated Pf3D7 parasites were considered. For upregulated proteins, proteins significantly upregulated (>1.5 fold) in both the MSO-treated parasites of two independent experiments and/or undetectable in the untreated controls but detectable in the MSO-treated parasites were considered.

The prevalence of preterm birth along with its associated mortality and lifelong morbidity warrant a better understanding of the underlying signaling events for better diagnosis and management of the condition. Placenta is an important transient organ that acts as a conduit between the fetus and mother. Any physiological and pathological changes taking place in the feto-maternal system are directly reflected in the placenta, making it a fitting choice to study the altered signaling mechanisms that are play. We undertook independent data acquisition of clinical placenta samples (n=40), obtained from Garbh-Ini cohort, to study their comparative protein profiles in spontaneous preterm vs term birth condition. When label-free quantitation (LFQ) was carried out, it yielded 23 differentially expressed proteins (DEPs) in the case-control comparison.
