Protein posttranslational modification is an indispensable regulatory element that can fine-tune protein functions and regulate diverse cellular processes. Lysine 2-hydroxyisobutyrylation (Khib) is a protein posttranslational modification that was recently identified and is thought to play a role in a wide variety of active cellular functions.

In this report, for the first time, we comparatively studied the 2-hydroxyisobutyrylation proteome in peripheral blood mononuclear cells from a biopsy-proven immunoglobulin A nephropathy (IgAN) group and a normal control group based on liquid chromatography-tandem mass spectrometry.

Altogether, 7405 proteins were identified and added to a Khib library. Of these proteins, we identified 111 with upregulated expression and 83 with downregulated expression. Furthermore, we identified 428 Khib modification sites on 290 Khib-modified proteins, including 171 sites with increased modification on 122 Khib-modified proteins and 257 specific sites with reduced modification on 168 Khib-modified proteins.

Importantly, the abundance of lipocalin 2 was increased in the differentially expressed proteins, and a KEGG-based functional enrichment analysis showed that Khib proteins clustered in the IL-17 signaling pathway and phagosome category, which may have important associations with IgAN. Our data enlighten our understanding of Khib in IgAN and indicate that Khib may have important regulatory roles in IgAN.

Yes- mind the gap!Asthma, chronic obstructive pulmonary disease (COPD), and cystic fibrosis (CF) are major inflammatory respiratory diseases. Current mainstay therapy for asthma, and chronic obstructive pulmonary disease are corticosteroids, which have well-established side effect profiles. Phospholipids (PLs) are ubiquitous, diverse compounds with varying functions such as their structural role incell membrane, energy storage, and cell signaling.Recent advances in understanding PLs role as inflammatory mediators in the body as well as their widespread long-standing use as carrier molecules in drug delivery demonstrate the potential application of phospholipids in modulating inflammatory conditions. This review briefly explains the main mechanisms of inflammation in chronic respiratory diseases, currentanti-inflammatory treatments and areas of unmet need. The structural features, roles of endogenous and exogenous phospholipids, including their use as pharmaceutical excipients are reviewed. Current research on the immunomodulatory properties of PLs and their potentialapplication in inflammatory diseasesis the major section of this review. Considering the roles of PLs as inflammatory mediators and their safety profile established in pharmaceutical formulations, these small molecules demonstrate great potential as candidates in respiratory inflammation. Future studies need to focus on the immunomodulatory properties and the underlying mechanisms of phospholipids in respiratory inflammatory diseases.Parkinson's Disease (PD) is one of the most prevalent, recurrent and life-threatening neurodegenerative disease. However, the precise mechanism underlying this disease is not yet clearly understood. For understanding the pathogenesis of PD, it is essential to identify the symptoms along with the novel biological markers and to develop strategies which could lead towards the development of effective therapy. PD is associated with Lewy bodies (LBs) formation and the loss of dopaminergic neurons in the substantia nigra pars compacta of mid brain region. For the improvement in treatment strategiesas well as understanding the pathophysiology of the PD in number ofanimal models have been introduced that can recapitulatethe pathophysiology, motor and non-motor symptoms of PD. selleck inhibitor In contrast to mammalian models like rodents, mice and monkey, Drosophila is easy to handle as well as it maintenance cost is low.Due to the anatomical differencesin the brain and other major organsof human and fly,the issues of standardizing the methods or experiments to analyze behavioral aspects (walking, writhing, eating and sleeping) are difficult in flies. Thepresent review highlights the studies carried out for PD since 2000, using Drosophila melanogaster.

Ginkgo biloba is a commonsymptomatic treatment for cognitive impairment, although data on its efficacy are controversial.

The aim of the current study was to evaluate the effectiveness of standardized Ginkgo biloba extract EGb761® (Tanakan®) on the improvements in cognitive functions over 24 months in a local cohort of patients diagnosed with amnestic mild cognitive impairment (aMCI).

This multicentre non-interventional study included 500 eligible patients with aMCI treated with 120 mg/day standardized Ginkgo biloba extract EGb761® (Tanakan®). Patients were evaluated using several scales for assessment of cognition, memory, activities of daily living and depression (MMSE, FAQ, CGI, HAM-D) at baseline and every 6 months thereafter for a 24-month period. The median change in MMSE at the 24-month follow-up was the primary outcome of the study.

A statistically significant increase of 2 points in the median MMSE score was obtained. In patients with other concomitant cognitive disorders, the improvement in MMSE was less significant. Tanakan® improved memory impairment (using the delayed recall test) and the ability to accomplish activities of daily living (mean FAQ score, 1.7); it also decreased the severity of depression (mean HAM-D score, 2.4) at the end of the study. More than 80% of the patients showed at least minimal improvement of their condition as assessed by the CGI-Improvement Scale.

The administration of EGb761® (Tanakan®) led to a significant improvement of cognitive decline, memory, activities of daily living and depression in subjects with aMCI over 24 months.

Neuroinflammation plays a pivotal role in the onset of several neurodegenerative disorders and is considered a typical feature of these disorders. Microglia perform primary immune surveillance and macrophage-like activities within the central nervous system. Activated microglia are predominant players in the central nervous system response to damage related to stroke, trauma, and infection. Moreover, microglial activation per se leads to a proinflammatory response and oxidative stress. During the release of cytokines and chemokines, cyclooxygenases and phospholipase A2 are stimulated. Elevated levels of these compounds play a significant role in immune cell recruitment into the brain. Cyclic phospholipase A2 plays a fundamental role in the production of prostaglandins by releasing arachidonic acid. In turn, arachidonic acid is biotransformed through different routes into several mediators that are endowed with pivotal roles in the regulation of inflammatory processes. Some experimental models of neuroinflammation exhibit an increase in cyclic phospholipase A2, leukotrienes, and prostaglandins such as prostaglandin E2, prostaglandin D2, or prostacyclin. However, findings on the role of the prostacyclin receptors have revealed that their signalling suppresses Th2-mediated inflammatory responses. In addition, other in vitro evidence suggests that prostaglandin E2 may inhibit the production of some inflammatory cytokines, attenuating inflammatory events such as mast cell degranulation or inflammatory leukotriene production. Based on these conflicting experimental data, the role of arachidonic acid derivatives in neuroinflammation remains a challenging issue.

Prostate cancer(PCa) has the second-highest morbidity and mortality rates in men. Possessing facile surface chemistry and unique optical properties make silica nanoparticles(SiO2-NPs) promising cancer therapy materials.

This study aimed to investigate the effects of SiO2-NPs and their derivatives, including SiNP-NH2, SiNP-Cl, and SiNP-SH against PCa and clarify their molecular mechanism on cell death, gene, and protein expressions.

Following the synthesis and derivation of SiO2-NPs, their characterization was carried out using TEM, DLS, BET, and FT-IR. Cytotoxic properties of the compounds were investigated against different human cancerous cells, including HUH-7, A549, DLD-1, HeLa, NCI-H295R, and PC-3, as well as human healthy epithelium cell line PNT1A.

SiNP-NH2, SiNP-Cl, and SiNP-SH dose-dependently inhibited the proliferation of PC-3 cells with an IC50 value as 55.46 µg/mL, 55.09 µg/mL and 72.89 µg/mL, respectively.SiNP-SH significantly(p<0.0001) inhibited metastasis and invasion of PC-3 cells( the increased level of Smad-4 has also implicated the decreased cell proliferation. Hence, low sized SiNP-SH nanoparticles might be a suitable candidate for the treatment of human PCa.

Different studies have been performed to investigate the stem cell administration as promising tool for recovery of injured tissue in Multiple Sclerosis (MS), the most common demyelinating disease.

In the present systematic review, the electronic databases of PubMed and ScienceDirect were searched to screen English language studies published until April 2020.

The results obtained from experimental autoimmune encephalomyelitis (EAE) animals revealed that modified mesenchymal stem cells (MSCs) transplantation was associated with remyelination, inflammation suppression and oligodendrocyte precursor cells regeneration. Clinical trials indicated that 70% of the patients with MS showed disease stabilization following MSCs administration.

Although MSC therapy has showed to be effective in the improvement of some patients with MS, designing of larger placebo-controlled clinical trials with MSCs expressing immune-regulators or MSCs-exosomes may provide the novel viewpoint in the treatment of MS.

Functional gastrointestinal disorders are often extremely distressing for the infant and parents, leading to infant discomfort and crying, parental anxiety, repeated healthcare consultations, and escalating healthcare costs.

In this narrative review we analyzed the relationship between maternal psychological status during pregnancy and postpartum and the main infantile functional gastrointestinal disorders.

The narrative reviewwas conducted searching scientific databases for articles reporting on infantile functional gastrointestinal disorders in association with maternal depressive or anxiety disorders.

seven studies were suitable.

Maternal psychological disorders may be correlated to infantile functional gastrointestinal disorders. Whether it is the excessive crying that favors the onset of maternal psychological disorders or, in contrast, an altered attachment style due to the maternal status that facilitates the onset of functional gastrointestinal disorders in the infant is still an open question.
