سرطان معده جزء یکی از شایع ترین بیماری ها در دنیا محسوب می شود؛ به نحوی که سالانه حدود یک ملیون نفر به این سرطان مبتلا می شوند. سرطان معده دومین عامل مرگ و میر های مرتبط با سرطان را به خود اختصاص داده است. اکثر سرطان_های انسانی یک هتروژنی ذاتی در پروفایل ژنتیکی خود نشان می دهند. مطالعات متعددی مشخص کرده اند که تغییر در نحوه ی پیرایش پیش ساز mrna نقش بارزی در پیشرفت بیماری ها بازی می کند. علاوه ...
علی رغم کاهش چشم گیر در نرخ بروز و مرگ و میر، سرطان معده همچنان یکی از بد خیم ترین سرطان ها در سر تا سر جهان از جمله ایران به شمار می آید. سرطان معده به هر گونه نئوپلاسم بد خیم وسعت یافته بین ناحیه ی اتصال مری و معده تا پیلور اشاره دارد. ژن zfx کد کننده ی یکی از اعضای خانواده ی پروتئین های انگشت روی می باشد که تنظیم کننده رونویسی مشترک برای خود نوسازی در سلول های بنیادی جنینی (esc) و سلول های ب...
Zinc-finger protein X-linked (ZFX) was recently identified as a novel oncoprotein in several human malignancies. In this study, we examined the correlation between ZFX expression and the clinical characteristics of stage II/III CRC patients, as well as the molecular mechanism by which ZFX apparently contributes to CRC tumor progression. Using immunohistochemistry, we detected expression of ZFX ...
OBJECTIVE To investigate the role of Zinc finger X-chromosomal protein (ZFX) in oncogenesis of Osteosarcoma tumor. METHODS Here, we first conducted an expression analysis of ZFX in Osteosarcoma cell lines. Then, we constructed ZFX-specific small interfering RNA (siRNA)-lentiviral vector that is capable of effectively inhibiting the expression of ZFX gene in human Osteosarcoma Saos-2 cells, an...
BACKGROUND This study was designed to assay the expression of zinc finger protein X-linked (ZFX) in renal cell carcinoma (RCC) tissues and evaluate the correlation between ZFX expression and prognosis of RCC patients. MATERIAL AND METHODS The expressions of ZFX mRNA in 53 RCC tissues and 51 normal tissues were determined by quantitative real-time polymerase chain reaction (qRT-PCR). Immunohis...
Zinc finger protein X-linked (ZFX) is frequently upregulated in multiple human malignancies and also plays a critical role in the maintenance of self-renewal in embryonic stem cells. However, the role of ZFX in liver cancer stem cells (CSCs) remains obscure. We observed that the elevated expression of both ZFX and epithelial cell adhesion molecule (EpCAM) was associated with aggressive clinicop...
BACKGROUND X-chromosome-coupled zinc finger protein (ZFX) in the Zfy protein family is abundantly expressed in both embryonic and hematopoietic stem cells (HSCs). ZFX exist in various tumor cells and is correlated with proliferation and survival of tumor cells. As a malignant tumor with high invasiveness, hepatocellular carcinoma (HCC) may present resistance against chemotherapy and features of...
Stem cells (SC) exhibit a unique capacity for self-renewal in an undifferentiated state. It is unclear whether the self-renewal of pluripotent embryonic SC (ESC) and of tissue-specific adult SC such as hematopoietic SC (HSC) is controlled by common mechanisms. The deletion of transcription factor Zfx impaired the self-renewal but not the differentiation capacity of murine ESC; conversely, Zfx o...
The Zfy gene is located on the Y chromosome of placental mammals and encodes a zinc finger protein which may serve as the primary sex-determining signal. A related gene, Zfx, is similarly conserved on the X chromosome. Unlike that in most mammals, the mouse genome contains four homologous zinc finger loci: Zfy-1, Zfy-2, Zfx, and Zfa (on an autosome). We report that, in contrast to the mouse Zfy...
The ZFX gene on the human X chromosome is structurally similar to the ZFY gene, which may constitute the sex-determining signal on the human Y chromosome. ZFY and ZFX diverged from a common ancestral gene, as evidenced by similarities in their intron/exon organization and exon DNA sequences. The carboxy-terminal exons of ZFY and ZFX both encode 13 zinc fingers; 383 of 393 amino acid residues ar...
