Key Gene Causing Breast Cancer Metastasis Discovered
The treatment and understanding of cancer diseases is one of the greatest challenges in medicine. Metastasis, or the spread of cancer cells to other parts of the body, poses serious problems in the progression of the disease. Researchers are continuously working to uncover the behavior of tumors and the mechanisms of their spread. The latest research has revealed a special gene, SATB1, which has opened new possibilities in cancer treatment. Metastases are extremely concerning, as the majority of deaths from cancer occur as a result of this phenomenon. In the case of breast cancer, statistics show that only 25% of women with metastatic conditions survive beyond five years, and only…

Dark Circles – Possible Causes and Background Information
The appearance of dark circles is an aesthetic problem for many people, giving a tired and possibly older appearance. The term “dark circles” refers to the darker discoloration of the skin under the eyes, which can spread starting from the inner corner of the eye. This appearance should not be confused with bags under the eyes, which refer more to a swollen, edematous condition. In the case of dark circles, the condition of the skin and the underlying capillaries play a key role. The color of the circles can vary, such as bluish-purple, brownish, or grayish shades, depending on what causes the discoloration. Often, the underlying causes of such conditions…

A genetic mutation is behind severe hypoglycemia
The sudden drop in blood sugar levels, known as hypoglycemia, is a serious health issue that affects many people’s lives. Various factors, including genetic ones, can underlie this condition. Regulating blood sugar levels is vital for the healthy functioning of the body, as glucose is one of the main energy sources. When blood sugar levels drop too low, it can cause many uncomfortable and life-threatening symptoms. Hypoglycemia is common among diabetics, especially those who manage their condition with insulin. However, hypoglycemia can also be caused by certain genetic disorders that affect the functioning of hormones and genes responsible for blood sugar regulation. Recent research indicates that mutations in the AKT2…

Genetic Origin of Breast and Ovarian Tumors
The breast and ovarian cancers are among the most prevalent types of tumors affecting the female population, with a significant portion of cases attributed to genetic factors. Hereditary predisposition can arise from mutations in the BRCA1 and BRCA2 genes, which play a key role in the repair of DNA in cells. Correcting DNA errors is essential for maintaining the stability and integrity of cells, and if these mechanisms are compromised, it can lead to cancerous processes. It is worth mentioning that BRCA mutations can occur not only through inheritance but can also arise spontaneously. For individuals with BRCA1 and BRCA2 mutations, recognizing the risk is particularly important, as these genetic…

Attention Disorder: The Role of Genes Instead of Upbringing
The temperament of children has long intrigued scientists, as this phenomenon affects not only their development but also their social interactions and academic performance. Defining temperament is a complex process involving both genetic and environmental factors. Recent research has sought to understand how certain genes and brain activity influence children’s behavior and emotional responses. The relationship between the frontal cortex and temperament The role of the frontal cortex in the development of children’s temperament is significant. This area of the brain is primarily responsible for complex emotional and cognitive functions. Increased activity in the left frontal cortex is generally associated with calmer, more manageable children who can quickly adapt to…

The biological age of the organism may warn of cancer risk
The process of youth and aging is extremely complex and not solely dependent on genetics. Thanks to the advancement of science, we are now able to measure how quickly our bodies age. Understanding our biological age creates new opportunities for more effective treatment of cancer and can also help in prevention. The incidence of cancer, particularly among young adults, has increased alarmingly in recent times. Worldwide, cases of colorectal cancer among young people have risen dramatically, indicating a 60-70% increase even in the most well-off countries. In Hungary, the situation is particularly severe, as cancer diseases represent the highest proportion in mortality statistics. The number of cancer cases here translates…

Endre Czeizel Has Died – The Renowned Medical Geneticist Has Passed Away
Czeizel Endre, a prominent figure in Hungarian medical genetics, dedicated his entire life to the service of scientific research and popularization of knowledge. His work has impacted the lives of many individuals, and his recognition is significant not only within professional circles but also among the general public. After his death, many remember him as someone who made the world of genetics more understandable for laypeople. His activities in the field of medical genetics contributed to the popularization of genetic screenings, which can reduce the risk of numerous diseases. Leukemia, the most common type of cancer among children, is particularly important, as statistics show it is much more common among…

Cloning – Legal and Prohibited Uses
The process of cloning is a biological phenomenon through which a genetic copy of a cell, tissue, or even an entire organism is created. Many people identify the topic solely with the cloning of whole organisms, although it encompasses a much broader spectrum, including medical applications. The roots of the concept of cloning trace back to the Greek word “klon,” which meant a sprout or twig and originally referred to the vegetative propagation of plants. Among the natural forms of cloning are identical twins, who share the same genetic information. Cloning is not a new phenomenon; it has long been applied in plants, for example, through division or cuttings. In…

Genetics does not determine fate, but indicates predisposition to disease.
The field of genetics is a complex science that examines the relationships between biological inheritance and various diseases. Many tend to think that genetic information automatically determines the future and the likelihood of disease development; however, this is not entirely true. Research shows that genetic predispositions are not the same as fate. Significant differences exist, especially in chronic diseases such as asthma, between predisposition and the actual manifestation of the disease. Asthma prevalence Asthma is becoming increasingly common, particularly among children. Recently, the incidence of the disease has significantly increased, making it one of the most prevalent childhood illnesses in Hungary. This typically chronic inflammatory lung disease involves numerous immunological…

The Mysteries of DNA – Uncovering Our Genetic Heritage
A modern scientific research is continuously making new discoveries about the human genome, which plays a key role in understanding genetic health. The human genome, which carries the genetic information of humans, has an extremely complex structure and often contains segments that are not fundamentally necessary for maintaining a healthy life. This phenomenon raises the question of why these non-essential genes are needed and how they affect human health. The Role of Non-Essential Genes During the evolutionary process, genes have continuously changed, and in many cases, the role of non-essential segments has diminished. The scientific community is increasingly concluding that certain parts of the human genome can be omitted without…
