Oxidative stress and protein carbonylation is implicated in aging and various diseases such as neurodegenerative disorders, diabetes, and cancer. Therefore, the accurate identification and quantification of protein carbonylation may lead to the discovery of new biomarkers. We have developed a new method that combines avidin affinity selection of carbonylated proteins with iTRAQ labeling and LC ...
The integrity of the genome depends on diverse pathways that regulate DNA metabolism. Defects in these pathways result in genome instability, a hallmark of cancer. Deletion of ELG1 in budding yeast, when combined with hypomorphic alleles of PCNA results in spontaneous DNA damage during S phase that elicits upregulation of ribonucleotide reductase (RNR) activity. Increased RNR activity leads to ...
A guanine derivative with an acyclic side chain, 2-hydroxyethoxymethyl, at position 9 has potent antiviral activity [dose for 50% inhibition (ED(50)) = 0.1 muM] against herpes simplex virus type 1. This acyclic nucleoside analog, termed acycloguanosine, is converted to a monophosphate by a virus-specified pyrimidine deoxynucleoside (thymidine) kinase and is subsequently converted to acycloguano...
The ability of the fungal pathogen Cryptococcus neoformans to evade the mammalian innate immune response and cause disease is partially due to its ability to respond to and survive nitrosative stress. In this study, we use proteomic and genomic approaches to elucidate the response of C. neoformans to nitric oxide stress. This nitrosative stress response involves both transcriptional, translatio...
All organisms contain thioredoxin (TRX), a regulatory thiol:disulfide protein that reduces disulfide bonds in target proteins. Unlike animals and yeast, plants contain numerous TRXs for which no function has been assigned in vivo. Recent in vitro proteomic approaches have opened the way to the identification of >100 TRX putative targets, but of which none of the numerous plant TRXs can be speci...
زمینه و هدف: کمتحرکی در مقابل آن تمرین جزء عوامل مرتبط با شاخصهای آسیب کبدی بهشمار میروند. وجود این هنوز نقش بسیاری از تمرینهای ورزشی بهویژه تمرینات تناوبی مقاومتی مصرف برخی مکملهای غذایی جمله اسپیرولینا بر ایمنی التهابی کاملاٌ شناخته نشده است؛ بنابراین هدف پژوهش تعیین اثر هشت هفته مکملدهی هوازی فعالیت بافت کبد بیان ژن CXCL1 عضلة موشهای صحرایی نر بود.مواد روشها: نیمهتجربی، 60 سر موش ن...
کلزا یکی از گیاهان مهم روغنی می باشد که تنها بعد از سویا و نخل روغنی جایگاه سوم را در تولید جهانی به خود اختصاص داده است. این گیاه عضو خانواده براسیکا می باشد. یکی از مهمترین عوامل محدود کننده تولید دانه های روغنی از جمله کلزا مجموعه ای از آفات هستند که به این گیاه خسارت وارد می کنند. آفات حشره ای گیاهان روغنی کلزا، منحصراً مختص خانواده شب بو هستند که از جمله این آفات، آفات پروانه ای می باشند. آ...
Mammalian and fungal prions arise de novo; however, the mechanism is poorly understood in molecular terms. One strong possibility is that oxidative damage to the non-prion form of a protein may be an important trigger influencing the formation of its heritable prion conformation. We have examined the oxidative stress-induced formation of the yeast [PSI+] prion, which is the altered conformation...
