cell division discovery could offer fresh insight into cancer and blood test ...Danny ZuluagaThe document summarizes two scientific articles about recent discoveries related to cancer research. The first article discusses the discovery of protein complexes that help distribute DNA correctly during cell division, which could provide new insights into cancer. The second article reports that a simple blood test may be able to detect gene mutations associated with cancers like pancreatic cancer by analyzing DNA in blood exosomes shed by tumor cells, avoiding the need for tumor biopsies. These discoveries could help advance cancer screening and drug development.

Presentacion plegablelinamaherreSatellite DNA sequences that are normally inactive are overexpressed in many common tumor cells. Two types of satellite DNA called HSATII and ALR showed increased levels in human tumor studies. Using mouse models, researchers also found higher levels of satellite DNA in pancreatic, colon, and lung cancers. The tumor suppressor protein p53 plays a role in regulating organ size by inducing apoptosis in stressed cells and limiting further cell growth, allowing damaged tissue to repair itself. Overexpression of satellite DNA and dysregulation of p53 may both contribute to uncontrolled cell growth and proliferation in cancer.

Wilmarie reflection 1 final
Wilmarie reflection 1 finalWilmarie Morales-SotoStem cells can divide into specialized cell types or more stem cells. They are found in organs like the liver, lungs and colon as well as the brain where they are called glia. Gliomas are brain or spine tumors that resemble glia cells. Glioblastoma multiform is the most common and dangerous glioma tumor. Researchers presented findings showing that adding miRNA to glioma tumor cells can make them vulnerable to chemotherapy, which previously had little effect. These results could help develop treatments to cure glioma tumors and provide insights for cancer and neurological research.

"Viruses in genome important for our brain." and "Study finds new target for ...María Manuela Echavarría Noreña- A study found that endogenous retroviruses, which make up 8-10% of our genome, may play an important role in gene expression and development in the brain. Retroviruses can affect gene expression through a protein called TRIM28. Understanding this could provide insight into genetic brain diseases.
- A separate study discovered that proteins involved in lipid and membrane formation are synthesized more efficiently during cell division. Identifying the proteins and processes involved in cell division could lead to new ways of controlling cell division and potentially treating diseases like cancer.

Central Dogma Of Genetic InformationManuela VelezThis document discusses the central dogma of genetics, how DNA is replicated and transcribed into RNA which is then translated into protein. It also discusses how mutated genes can cause cancer and be inherited. Studies found that inherited susceptibility to bowel cancer is common in families with a history of the disease, suggesting wider genetic testing. Retroviruses can integrate their RNA genome into host DNA using reverse transcriptase. Endogenous retroviruses make up about 5% of human DNA and may have played an important role in brain development and function over evolution. Retroviruses could potentially be used in gene therapy applications.

Are we Still Missing the Target in Trying to Prevent and Treat Human Cancers?...CrimsonpublishersCancerSolving the problem of preventing or treating cancers is still a major problem. While much is known about those multi-disciplinary contributors to the initiation, promotion and progression phases of human cancers, major hurdles to efficacious prevention and treatment involve, while recognizing that there are many known factors that can influence human carcinogenesis, little integration of this knowledge has been used. This brief “Opinion” paper hypothesizes that, by recognizing the multi-stage, multi-mechanism process of carcinogenesis, the roles of organ-specific adult stem cells as the “targets for two types of “cancer stem cells”, and new strategies for nutritional /dietary intervention, could help in the prevention of early susceptibility for cancers later in life, as well as for treatment for the two very different “cancer stem cells”. “In this light, a new perspective for therapeutic intervention by directing differentiation and restoring communications between cancer cells is certainly relevant, and the example of gap junctions is illuminating” .
The molecular times
The molecular timesjonyfive5Scientists are researching genetic treatments to prevent disease by applying genetics to medical care and developing new therapies. A recent study found that extracts from axolotl oocytes were able to reactivate tumor suppressor genes in cancer cells and stop cancer growth in breast cancer cells for 60 days by changing epigenetic marks on DNA. However, simply sequencing genes to identify genetic variants does not provide a full picture of human disease, as the impact of variants needs to be determined through functional studies using good experimental models to better understand complex inherited disorders.

Scientists first researched mouse bone marrow stem cells in 1963 and have since tried using bone marrow stem cells for transplants. Stem cells can potentially be used to treat nervous system diseases, injuries, genetic disorders, and more because they can become any cell needed. However, embryonic stem cell research requires destroying embryos and carries cancer risks, causing ethical debates. Now, scientists can turn adult skin cells into stem cells to avoid rejection and new methods avoid cancer risks.
Organoid Poster
Organoid PosterFranklin WilsonOrganoids are small 3D tissues that mimic the function of organs. They were first developed in 2007 and have since been used to model many organs including the brain, pancreas, and heart. While organoids are still in the early stages of research, they show promise for medical and scientific uses. Organoids are made by harvesting stem cells from an organ and culturing them in a gel environment where they self-organize into ball-like structures that resemble miniature organs. Researchers hope organoids can be used for drug testing and personalized medicine without the need for animal testing. As techniques for growing organoids continue to advance, so too will their potential applications.

Bacterial cellulose was produced with the addition of 1% chondroitin sulfate to the culture medium. Characterization with SEM, FTIR and XRD showed the chondroitin sulfate was incorporated and did not significantly alter the bacterial cellulose structure. The bacterial cellulose nanocomposites were also able to incorporate calcium phosphate when soaked in simulated body fluid, as seen with SEM, FTIR and XRD analysis. Future work will investigate cell adhesion and viability on the scaffolds.

Researchers developed a hydrogel nanocomposite containing halloysite nanotubes doped with growth factors that provides structural support within the gel. When mesenchymal stem cells and pre-osteoblasts were cultured in the nanocomposite, they differentiated into osteoblasts, proliferated, synthesized type I collagen matrix that mineralized, and increased protein synthesis including bone-specific proteins. This approach allows control over cell behavior and differentiation in 3D to engineer complex tissues for regenerative medicine.

Recent Advances In BioPolymers And Its Applications
Recent Advances In BioPolymers And Its ApplicationsArjun K GopiBiopolymers are materials that are biodegradable, derived from renewable resources, or both. Common biopolymers include polylactic acid (PLA), polyhydroxyalkanoates (PHAs), and cellulose. Biopolymers are increasingly important due to their environmentally-friendly properties and potential to replace petroleum-based plastics. However, biopolymers currently only account for about 1% of the global plastic market. The use of nanomaterials to create bionanocomposites can help improve biopolymer properties and expand their applications in areas like packaging, textiles, agriculture, and biomedicine.

Researchers have identified why cancer tumours thrive even with no blood or e...Lucy KeenResearchers at the CNIO in Spain discovered a mechanism that allows cancer cells to survive without glucose by detecting glucose levels and activating different biochemical pathways. When glucose is present, cancer cells use one pathway to thrive, and when it is absent, they trigger an alternative pathway to survive while cut off from nutrients. This explains why tumors can resist drugs that aim to starve them and continue growing even without a blood supply. The findings provide insight into cancer's ability to adapt and survive stressful conditions.

Junior papertrentpierceStem cell research holds promise to treat many medical conditions but also faces ethical controversies. While embryonic stem cells are fully pluripotent, their use raises concerns about human embryo destruction. Alternatives like induced pluripotency and somatic cell nuclear transfer aim to achieve the benefits of embryonic stem cells without using embryos. Government policies on funding stem cell research have varied between administrations and some regulations are criticized for being hastily made and hindering scientific progress. Overall, stem cell research could help millions but also generates religious and ethical debates around topics like cloning and embryo use that societies are still grappling with.

PharmacologyThe document discusses metastasis and proposes some new hypotheses about the process. It suggests that the traditional view of metastasis as a random filtration process is an oversimplification. Instead, it hypothesizes that secondary organs may play an active role in determining the location of metastases by providing a favorable incubation environment for cancer cells. The document reviews examples from biology like symbiotic relationships and fetal development to draw parallels with how secondary organs may interact with metastatic cells. It proposes experimental studies to investigate cancer cell migration properties and the role of secondary organs in supporting cancer cell growth.

Plegable molecular Lina AcevedoThe document discusses two scientific studies. The first study found that a specific stage in the cell cycle (G1 phase) being altered can lead to uncontrolled cell growth and cancer development when telomeres are shortened. The second study discovered that after a heart attack in zebrafish, muscle cells from the undamaged atrium migrated into the damaged ventricle and transformed into ventricular cells, helping regenerate the heart tissue and restore cardiac function.

Molecular Biology, Daniela Alarcón.Daniela AlarcónScientists have discovered new ways to trap and kill the malaria parasite. Researchers found that blocking the pore through which the parasite communicates with the outside of red blood cells fatally imprisons the parasite, preventing it from stealing resources and eliminating waste. Separate research identified a protein that guides folding and unfolding of parasite proteins, and blocking this protein could prevent transmission through the pore. Stem cell scientists have also developed a method to track gene expression in specific cell types in the kidneys of rats to better understand acute kidney injury and identify early signs of damage.

Chromosomes, chromatin and cellular cycle 
Chromosomes, chromatin and cellular cycle Kamila VaronCellular cycle is important in cell growth, development, and death. Studying this area helps understand diseases associated with these processes. Researchers identified the cell of origin in leukemia cases using mouse experiments expressing MLL-AF2. They analyzed different cell states in mice and a control group. Further studies may open new avenues for early cancer diagnosis and treatment. A gene mutation was found to cause brittle bone disease and other connective tissue issues in two families, showing one gene can cause multiple diseases. These studies increase understanding of known diseases and could reveal unknown ones, expanding human knowledge.
Stem Cell Essay Outline
Stem Cell Essay OutlineCheap Paper Writing Service The document discusses stem cell research and its potential benefits. It notes that stem cells can divide and renew themselves, are unspecialized, and can develop into specialized cell types. This allows them to be used for testing new drugs, developing cell-based therapies, and studying human development and diseases like cancer. The document outlines four main methods for inducing pluripotency in stem cells: viral vectors, DNA-based induction, RNA molecules, and recombinant proteins. It also discusses the debate around embryonic stem cell research, noting arguments from both supporters who see potential medical benefits, and critics who believe it destroys human life.

- 4. When it comes to medical innovation, this days the main interest is focus on molecular bases… …Reasearches recognize that studying how to improve a gene, code the posibility of finding better treatments or a cure for diseases are bigger and better.
- 5. BLOCKING CELL MOVEMENT TO STOP SPREAD CANCER Cancer, according to The National Institute of Cancer of USA, is the term used for abnormal cells that divides without control and can spread to different tissues.
- 6. Now-a-days, there are known more than a hundred types of cancer. A secondary cancer (Metastasis) is the one that spreads trough the body, following either linfatic or blood via. This type of cancer can be lodge in vital organs, as lungs or the brain, and thats why it is so dangerous.
- 7. Scientist found that changing the cell structure from a liquid (And fast) state to a solid (and slow) state the posibility of metastasis decrease. Using embryonic cells and studying its developing process, the LPA (Lysophosphatidic acid) was the molecule researches found that was in charge of changing the cell structure.
- 8. The cells will continue to travel in our body but with this change it would not be as easier as before to pass from a tissue to another. Plus, for scientist is less complex to stop a mase than a fluid.
