FUBP1, also known as Far Upstream Element Binding Protein 1, is a tumor suppressor gene located on the reverse strand of chromosome 1. The exact location of this gene is chr1:78,413,591-78,444,777. FUBP1 is a protein-encoded gene. This protein functions as an ATP-dependent DNA helicase. It regulates MYC expression by binding to a single-stranded far-upstream element upstream of the MYC promoter. It binds to multiple DNA elements. It may act as both an activator and repressor of transcription. [1] FUBP1 is a transcriptional regulator and fulfills an important function in the precise control of c-MYC transcription. The c-MYC protein is a transcription factor, which regulates the transcription of many different target genes that play in proliferation, …show more content…
The diseases associated with FUBP1 include oligodendrogliomas, astrocytomas, and oligoastrocytomas. Oligodendrogliomas are primary glial brain tumors and can be either low-grade (grade II) or high-grade (grade III). [2] Since oligodendrogliomas have a slow growth rate, they are often present for years before they are diagnosed. Nevertheless, the most common symptoms include: seizures, headaches, and personality changes. Altogether, the symptoms vary by location and size of the tumor. About 66 to 78 % of people with grade II oligodendroglioma survive for about 5 years after diagnoses, while 30 to 38 % of people with grade III will survive for about 5 years after they are diagnosed. [3] Astrocytoma is another type of brain cancer that stats in the cerebrum, which is the largest part of the brain, but can also appear in the cerebellum, which is the back of the brain. It is more common in men than in women. Like oligodendrogliomas, the most common symptoms of astrocytomas include: headaches, seizure, changes in behavior and memory loss. [4] Prognosis of astrocytomas depends on the type of astrocytoma. Altogether, a low-grade astrocytoma (LGA) has an 83 % 10-year overall survival, while the overall survival rate of a high-grade astrocytoma (HGA) range between 15-20%. In both oligodendrogliomas and astrocytomas, the FUBP1 locus is mutated which leads to the inactivation of
Glioblastoma is the most common and aggressive form of malignant brain cancer in adults. On average, 8 of every 100,000 people in the U.S. are diagnosed with glioblastoma every year – representing approximately 2% of all cancers diagnosed [1]. Glioblastoma tumors form when astrocytes, star-shaped cells which support and protect the brain, re-enter the cell cycle and start to rapidly divide. Because the brain is supported by a large network of blood vessels, tumors grow quickly and are difficult to remove surgically. Present treatments for glioblastoma are limited to surgery, radiation therapy, and chemotherapy; however, despite these interventions tumors are likely to regrow. Consequently, typical survival time following glioblastoma diagnosis is less than 2 years.
Perennial throughout all history, man’s adoration and abuse of power inevitably evokes his personal corruption. At creation, Adam and Eve succumbed to vices as they lusted for the power of wisdom. Similarly, in current civilization, men idolize money as it enhances their fame and influence on humanity. Ultimately, when a man’s ability surpasses any societal limitations, greed, lust, and pride tempt his morality which usually fails to persist. In his novel, the Narrative of the Life of Frederick Douglass, an American Slave, Frederick Douglas reminisces on personal experiences as a slave while concurrently investigating the paradoxical nature of Southern slaveholders. He delves into the mystery of a white man’s ability to suppress
Glioblastoma (pronounced like gleO blastoma) is an incurable brain cancer,Survival rate is usually measured in months.This became a word that was instantly defined, researched, dissected, feared, and tried to comprehend and understand by family,friends and acquaintances of Larry McKee (McKee)who was personally affected from this single word, it was quickly added to their vocabulary, because of the of the events that transpired on October 22, 2011 that forever changed lives “Glioblastomas are tumors that arise from the astrocytes- the star-shaped cells that make up the “glue-like,” or supportive tissue of the brain. These tumors are usually highly malignant (cancerous) because the cells reproduce quickly and they are supported by a large network of blood vessels.”(A.B.T A..) He was diagnosed with stage four.
Glioblastoma Multiforme (GBM) is a primary central nervous system (CNS) cancer that causes tumors of the glial cells in the brain. The third most frequently reported histology overall, and the most common malignant histology1. It’s also the most common and the most malignant primary central nervous system tumors2. GBM accounts for 15.1% of all primary brain tumors and 46.1% of primary malignant brain tumors1. The Central Brain Tumor Registry of The United States (CBTRUS) estimated that 24,790 new cases of primary malignant brain tumors to be diagnosed in the United States in 20161.
Neurofibromas may become apparent from ten to fifteen years of age. Symptoms like café-au-lait, freckling, and lisch nodules pose little to no health risk to a person. Neurofibromas are mostly a cosmetic concern but they can be psychologically distressing. Neurofibromas can grow inside the body and may affect organs and could be severely debilitating. Fifty percent of children with type one may have learning disabilities, hyperactivity, seizures, and speech impediments. Type two is less common but it also causes more tumors. Symptoms for type two include: schwannomas, brain tumors, tinnitus, cataracts at young ages, spinal tumors, balance problems, and atrophy. Schwannomas are tumors along the eighth cranial nerve. Tinnitus is ringing noises inside the ear, hearing loss, or deafness. Cataracts cause clouding in the lens of the eye. Atrophy is wasting of the muscles or organs. Hearing loss can begin as early as the person’s teenage
Choice “E” is the best answer. Glioblastoma multiforme (GBM) is the most common and most malignant of the glial tumors. GBMs may manifest in persons of any age, but they tend to more common in adults, with a peak incidence at 45-70 years. The clinical history of a patient with glioblastoma multiforme (GBM) is usually short (< 3 months in >50% of patients). Common presenting symptoms include: slowly progressive neurologic deficit, motor weakness, and headaches.Generalized symptoms of increased intracranial pressure include headaches, nausea and vomiting, cognitive impairment, and seizures. Neurologic symptoms and signs can be either general or focal and reflect the location of the tumor.General symptoms include headaches, nausea and vomiting, personality changes, and slowing of cognitive function. Focal signs include: hemiparesis, sensory loss, visual loss, and aphasia.
Glioblastoma Multiforme is an extremely aggressive brain tumor that can drastically alter how the body moves, a person’s memory, vision, emotion, thought, etc (GBM Guide). Having something in your brain that has the potential to drastically
Glioblastoma Multiforme accounts for about 17 percent of all tumors of the brain. These tumors
Astrocytoma are tumors that arise in the astrocytes of the brain. This specific tumor type can lead to effects such as headaches, seizures, memory loss, and changes in behavior when left untreated (“Astrocytoma”, 2014). Astrocytoma are graded in severity on a scale from I to IV based on the normality of the cells, with I being the least severe and IV being life threatening (“Astrocytoma”, 2014). For low grade astrocytoma, it is unclear as to which form of primary treatment is most beneficial, radiotherapy or neurosurgery, due to the fact that neurosurgery is often more effective in removing the tumor, but also exhibits a higher risk to the subject when the tumor is low grade (Kennedy, 2015). Other factors that may
The gene can be alternative spliced in exons 12, 14, 15 and 17 resulting in different mRNAs and protein isoforms. The CGG trinucleotide repeat in the non-coding part of the FMR1 gene is unstable, thus the repeat length varies among normal population, with normal individuals ranging from 6-55 repeats. The trinucleotide repeat often becomes unstable during maternal transmission to the next generation, giving rise to the expansion of the repeat. Individuals with 55-200 CGG repeats are considered premutation carriers, and in patients with FXS the CGG repeats are above 200 resulting in hypermethylation and therefore silencing of the gene’s CpG site in the promoter region (Willemsen R., 2011). Pietrobono and her team, studied the events prior to the inactivation of the FMR1 gene and demonstrated that the initial events seem to be histone deacetylation and H3-K9 methylation, followed by DNA methylation and H3-K4 demethylation (Pietrobono, R., Tabolacci, E., Zalfa, F., 2005). However, work carried out on human embryonic stem cells has proven that FMR1 inactivation is a result of downregulation of transcription and chromatin modifications, prior to DNA methylation (Willemsen R.,
In severe diffuse reactive astrogliosis, the astrocytes undergo proliferation, which results in overlapping processes that effect neighbouring cells, their functions and individual domains. Most of the astrocytes express GFAP and other genes. As a result, these changes cause the reorganization
Brain tumors grow from abnormal cells which can be cancerous or noncancerous. Symptoms of brain tumors are headaches, muscular weakness like difficulty walking, whole body balance disorder, gastrointestinal (nausea or vomiting), sensory disorder like pins and needles, cognitive or mental confusion, speech (impaired voice), and very common blurred vision. There are various treatments for brain tumors. One includes chemotherapy which kills cells growing or multiplying too quickly. Surgery like craniotomy, this is brain surgery where a piece of bone is removed from the skull. And radiation therapy that uses X-rays to kill abnormal cells. Cancer cells can break off from the tumor into the bloodstream where they can go anywhere in the body. Noncancerous and cancerous brain tumors occur in about 12 in 100,000 people a year.
Surgery is the treatment of choice for wellcircumscribed lesions (Figure 1D) and the factor strongly associated with outcome is the extent of surgical removal.6,7 Gross total resection leads to more than 90% long-term survival.7 Cerebellar pilocytic astrocytomas are resectable and adjuvant therapy is not indicated. Those arising from the brainstem are often not completely resectable and require adjuvant chemotherapy (carboplatin and vincristine) and consideration of radiotherapy at progression. A clinical trial of BRAF and MAPK pathway inhibitors (AZD6244) is underway.8 A recent study has reported long-term follow up (mean of 18.4 years) for 101 children with benign posterior fossa astrocytomas.6 Complete resection was achieved in half the
Brain cancer is the formation of a tumor or intracranial neoplasm abnormalities in the brain. The two main types of tumors are malignant or cancerous tumors and benign tumors. The spreading of cancer to other parts of the body is called metastasis. Detection of brain cancer is typically done using magnetic resonance imaging (MRI) and confirmed by biopsy. The class of the tumor falls into different categories and treatment is determined by the severity of the tumor. Although the cause of brain cancer is still mostly a mystery there are several risk factors that increase your chance of developing brain cancer: a hereditary condition known as neurofibromatosis, chemical exposure, Epstein-Barr virus and ionizing radiation. Although not proven it is believed that talking on the phone may increase the chances of brain cancer. Brain tumors are treated based on their size, location, type and severity of the tumor. Typically the tumor is removed in surgery and then the patient goes through radiation treatment. Early detection of a tumor greatly increases the odds that a patient will recover. The radiation kills cancerous cells at the same time it kills healthy cells. Because the healthy cells are also dying the effects off therapy are dangerous. The patients experience many side effects. A new treatment is being tested where nanoparticles are filled with genes for an enzyme that turns a compound into a potent killer
Glioblastoma is the most deadly form of brain cancer, accounting for over 15,000 deaths in 2015 alone, and is responsible for 52% of all primary brain tumors. There are 2.96 cases of glioblastoma for every 100,000 people. Glioblastoma is so fatal because it does not react to normal cancer treatments like radiation therapy, chemotherapy, and surgery the same way that other cancers do.
