If the development of traditional Chinese medicine is towards the macro direction, then the research of modern medicine and modern science on the human body is towards the micro angle!


    Bioengineering is a typical example.


    The use of human enzyme engineering, microbial engineering, genetic engineering and other means to study the human body.


    It is precisely because of this that we understand diseases through these bioengineering means.


    To put it bluntly, bioengineering is a tool!


    To study diseases and the human body.


    Genetic engineering is the most mysterious and the cause of many diseases.


    When many diseases cannot be explained, people begin to say that they are caused by genes.


    you ''re right!


    But why are people''s genes all right?


    Therefore, genes are not invariable, and genes are changing all the time!


    From the beginning of human evolution, from thousands of years ago and now, great changes have taken place in the gene structure.


    The changes of human gene structure are nothing more than several effects: 1. Environment; 2. Diet; 3. Other special effects.


    Therefore, as long as human beings develop one day, genes will change.


    What is the human body?


    The human body is a life body controlled by genes. Genes form substances that play human functions through transcription and translation, and participate in life as a part of the human body!


    The emergence of cancer, according to the theory of Mary Claire and Robert Weinberg, is genetic variation, which leads to the transcription and translation of things that are not needed by the human body, which leads to the emergence of special substances and the occurrence of cancer!


    Breast cancer is also a series of reactions caused by mutations in BRCA1 and BRCA2 genes.


    But how did it happen?


    This requires the analysis of the mutated BRCA1 and BRCA2 genes.


    This process is the most difficult place!


    It''s also where Mary Claire spent the most energy.


    As early as 2011, they won the Lasker medical award, and then spent ten years studying this mechanism.


    Then came the new drug rapani.


    Instead of studying new drugs, Chen Cang began to use the "molecular scalpel" to analyze the mutated BRCA1 and 2 genes with restriction endonuclease.


    At present, the type of molecular scalpel determines the height of gene level in the world!


    There are about 4000 kinds of molecular scalpels in China, while there are more than 5000 kinds in foreign countries with the leading development of genetic engineering!


    There are 1000 kinds of differences. It seems that there is not such a big gap, but... These subtle differences often determine the depth of the development of genetic engineering!


    These precise molecular scalpels can identify the specific nucleotides of duplex DNA molecules. Although they can''t reach the level of where to point, they can also be realized, and the error is not very large!


    Cutting off is simple and identification is the most difficult!


    After the establishment of Chen Cang''s laboratory, he did not invite so many top experts.


    After all, so many people in core technology are useless. One person is enough to be truly separated, and others are responsible for observation, cultivation and research.


    Therefore, these did not affect the progress of the experiment!


    However, in any case, the progress of the whole experiment began to be relatively fast.


    The key is that Chen Cang has a good attitude now!


    No hurry, no delay!


    The combination of work and rest while taking care of Qin Yue leads to the rapid progress of the operation!


    Unknowingly, it''s nearly the end of the year!


    On this day, Chen Cang, as usual, accompanied Qin Yue, who had a big stomach, to spread in the park.


    It snowed early today. The park was covered in silver and plain. It was very beautiful!


    Qin Yue is in a good mood. She wakes up naturally every day. When she wakes up, her mother-in-law makes delicious food. The most important thing is Chen Cang. He feels very happy with himself every day, even if it is a simple spread!


    "I want to drink milk tea!"


    "No, the doctor said not to drink!"


    "Fruit!"


    "You asked my son if he would agree?"


    "Your son wants to drink!"


    "Trust you!"


    The two talked and laughed. There were a lot of people in the park. When they saw Qin Yue, they all kindly smiled and asked to open the way. They occasionally said hello and asked for a few months.


    These aunts were very enthusiastic and told Qin Yue what to pay attention to.


    Qin Yue suddenly said, "husband, I''m so happy!"


    "You see, when you see that my stomach is big, give me back the way, the children give me their seats, and the aunts tell me some precautions!"


    Chen Cang smiled and nodded.


    At this time, Qin Yue suddenly said, "by the way, do you think the human body is like this? Generally, after getting sick, everyone will call 120, help and save people. Generally, after the body has a disease, there should be all kinds of cells and factors involved..."


    "Aren''t you recently studying the oncogene of breast cancer?"


    "You said, is there a possibility that there is a factor in the human body? In fact, it was the same, but after gene mutation, this signal is abnormally activated, resulting in a series of adverse reactions?"


    As soon as he said this, Chen Cang was in a hurry!


    The brain is running crazy!


    Yes!


    Maybe I have entered a misunderstanding.


    I think the mutation is only tumor suppressor genes BRCA1 and 2!


    But is there anything else?


    For example, the abnormal signal is also abnormally activated?


    Thinking of this, Chen Cang''s eyes lit up.


    "Did you think of something good?" Qin Yue said suddenly.


    Chen Cang smiled: "yes! You are really my lucky star!"


    Qin Yue smiled: "in fact, I sometimes worry about delaying your development!"


    Chen Cang shook his head and gently hugged Qin Yue: "didn''t I tell you at that time? Did I work hard for our better life?"


    Qin Yue smiled: "but you are not my Chen Cang now. You are still the Chen Cang of many people!"


    "You have to refuel!"


    "By the way, if you make achievements and win the grand prize, do I have to have a share?"


    Chen Cang smiled: "give it to you!"


    the second day!


    Chen Cang went directly to the laboratory and started a new research according to his own ideas!


    After a week of tossing, I really found a substance!


    It''s called insulin-like growth factor 2!


    The gene of this factor is very unstable, which is related to the invasiveness, risk, progression speed and prognosis of breast cancer.


    This discovery makes Chen Cang''s long stagnant research finally take a new turn!


    For a time, Chen Cang quickly began to conduct in-depth research on this special insulin growth factor 2.


    And at the same time!


    A small thing, but quietly appeared in the United States!


    And this matter looks small, but it may hide the rough waves!
