زمینه و هدف: مطالعات نشان داده‌اند داروهای ضدالتهابی غیراستروئیدی می‌توانند بر رشد و تکوین سرطان تأثیر‌گذار باشند. این مطالعه با هدف تعیین اثرات آسپرین و ایبوپروفن بر زنده‌مانی سلولهای سرطانی دهانه رحم (Hela) در مقایسه با سلولهای غیرسرطانی(Hek293) انجام شد. روش بررسی: در این مطالعه تجربی - آزمایشگاهی، سلولهای سرطانی دهانه رحم (Hela) و سلولهای غیرسرطانی (Hek293) به‌طور تصادفی به گروه کنترل...
Two gap junction proteins, connexin43 (Cx43) and connexin45 (Cx45), are coexpressed in many cardiac and other cells. Homomeric channels formed by these proteins differ in unitary conductance, permeability, and regulation. We sought to determine the ability of Cx43 and Cx45 to oligomerize with each other to form heteromeric gap junction channels and to determine the functional and regulatory pro...
The present study examined the potential application of Juglans mandshurica Maxim extracts (HT) for cancer therapy by assessing their anti‑proliferative activity, reduction of telomerase activity, induction of apoptosis and cell cycle arrest in S phase in HeLa cells. From the perspective of using HT as a herbal medicine, photomicroscopy and florescent microscopy techniques were utilized to char...
زمینه و هدف : سال هاست ثابت گردیده موسیقی بر فشار خون ، ضربان قلب ، سیستم تنفس و عملکردهای دگر بدن موثر است تاثیر موسیقی بر سیستم ایمنی نیز در برخی پژوهش ها ذکر گردیده است چون تاثیر موسیقی بر سیستم ایمنی در ایران تاکنون مورد بررسی قرار نگرفته است این پژوهش به منظور انجام گردید. تعیین تاثیر سه نوع موسیقی بر روی سلولهای ایمنی مبتلایان به رینیت آلرژیک انجام گرفت. روش بررسی : این پژوهش از نوع مداخل...

Bard) The viability and activity of HeLa cells were probed using scanning electrochemical microscopy (SECM). The feedback generated by HeLa cells during scanning depends on the electrochemical mediator. Living HeLa c...
HeLa is the most widely used model cell line for studying human cellular and molecular biology. To date, no genomic reference for this cell line has been released, and experiments have relied on the human reference genome. Effective design and interpretation of molecular genetic studies performed using HeLa cells require accurate genomic information. Here we present a detailed genomic and trans...
One of the major groups of microtubule-associated proteins (MAPs) found associated with the microtubules isolated from HeLa cells has a molecular weight of just over 200,000. Previous work has demonstrated that these heLa MAPs are similar in several properties to MAP-2, one of the major MAPs of mammalian neural microtubules, although the two types of proteins are immunologically distinct. The 2...
Gap junctional communication modulates intercellular calcium signaling in many cell types. We have investigated whether gap junctional communication modulates calcium oscillatory behavior of cells responding to an agonist. Extracellular UTP induced calcium oscillations in 70% of HeLa cells cultured in monolayer, and neighboring cells oscillated independently of each other. In HeLa cell transfec...
objective: cervical cancer is the second most common cause of death from cancer in women throughout the world. the aim of this study was to evaluate the cytotoxic activity of kelussia odoratissima (k. odoratissima) extract associated with radiotherapy in cervical cancer cells (hela cell line).materials and methods: different concentration of the extract (25-500µg/ml) was tested in hela cell lin...
