The transcription repressor Bach2 has been proposed as a regulator of T cell quiescence, but the underlying mechanism is not fully understood. Given the importance of interleukin-2 in T cell activation, we investigated whether Bach2 is a component of the network of factors that regulates interleukin-2 expression. In primary and transformed CD4＋ T cells, Bach2 overexpression counteracted T cell ...
Through their functional diversification, distinct lineages of CD4+ T cells play key roles in either driving or constraining immune-mediated pathology and anti-tumor immune responses. Transcription factors are critical in the generation of cellular diversity, and negative regulators antagonistic to alternate fates often act in conjunction with positive regulators to stabilize lineage commitment...
The malignant phenotype of chronic myeloid leukemia (CML) is due to the abnormal tyrosine kinase activity of the Bcr-Abl oncoprotein. We have previously reported that expression of the Bach2 transcription factor, which induces apoptosis in response to oxidative stress, is greatly reduced in CML cells. Because these cells are resistant to apoptosis, we tested whether Bach2 could also be regulate...
Two transcription factors, Pax5 and Blimp-1, form a gene regulatory network (GRN) with a double-negative loop, which defines either B-cell (Pax5 high) or plasma cell (Blimp-1 high) status as a binary switch. However, it is unclear how this B-cell GRN registers class switch DNA recombination (CSR), an event that takes place before the terminal differentiation to plasma cells. In the absence of B...
The aim of the present study was to explore the mechanism through which miR-130a-3p affects the viability, proliferation, migration, and invasion of nasopharyngeal carcinoma (NPC). Tissue samples were collected from the hospital department. NPC cell lines were purchased to conduct the in vitro and in vivo assays. A series of biological assays including MTT, Transwell, and wound healing assays w...
Bach2 is a transcription factor required for affinity maturation of B cells. A recent study reveals, quite unexpectedly, that Bach2 also plays a key role in the pre-B cell receptor checkpoint and functions as a tumor suppressor in pre-B cell acute lymphocytic leukemia.
مقدمه: سرطان پستان، یکی از دلایل اصلی مرگ‌و‌میر در زنان میباشد. ژن BACH2 برای تنظیم تکوین و عملکرد انواع سلولهای ایمنی (سلول B، T و ماکروفاژ) نیاز میباشد. ژن BACH2 یک لوکوس مستعد کننده غالب برای چندین بیماری خودایمن و آلرژی میباشد، با این وجود بیان و عملکرد بالقوه BACH2 در سرطان پستان هنوز مشخص نشده است، لذا مطالعه حاضر با هدف بررسی بیان ژنی BACH2 در نمونههای توموری پستان انجام شد. روش کا...
Heme binds to proteins to modulate their function, thereby functioning as a signaling molecule in a variety of biologic events. We found that heme bound to Bach2, a transcription factor essential for humoral immunity, including antibody class switch. Heme inhibited the DNA binding activity of Bach2 in vitro and reduced its half-life in B cells. When added to B-cell primary cultures, heme enhanc...
BACKGROUND Autoimmune disease is one of the leading causes of morbidity and mortality worldwide. In Addison's disease, the adrenal glands are targeted by destructive autoimmunity. Despite being the most common cause of primary adrenal failure, little is known about its aetiology. METHODS To understand the genetic background of Addison's disease, we utilized the extensively characterized patie...
