Chapter 1880 My Scalpel Is the Most Fashionable! (Delivered at Five O'clock)

The chairman of Xinji, Karimos, also has a headache!

This year, I still want to compete with the Roche Group for the top spot in the oncology drug company, but now... this happened.

"Dr. Marie Claire, what do you... think?"

Marie Claire smiled: "I don't think it's a bad thing."

"I think it should be Professor Chen Cangchen who wants to study this topic!"

At this time, Robert Weinberg suddenly said: "Could it be...Professor Chen Cang discovered something new?"

Hearing this sentence, the room suddenly fell silent!

Everyone has heard of Chen Cang's name. Who in the medical system does not know about China's sudden rise and new stars.

However, Chen Cang is not engaged in basic research, is he?

A clinical surgeon has an irreconcilable relationship with tumor gene-targeted drugs...

Marie Claire laughed when she heard the sound: "How can it be so simple?"

"We have been studying for so long to make these progress, how can there be such a fast speed?"

"Besides, the tools used in China's bioengineering and genetic engineering are already outdated, and they can't achieve precise DNA cutting at all!"

Hearing what Marie Claire said, Robert did not object.

Because genetic engineering is really a very restrictive and powerful subject!

If we say that genetic engineering is to operate on genes.

Then it is bound to need to use: scalpels, suture needles, stage and other things.

And the sharp knife of genetic engineering should be called "molecular scalpel", that is, restriction enzyme!

And his suture thread is called "molecular suture", which is DNA ligase!

The gene carrier is the carrier of the "molecular carrier"!

And these three tools are the core tools of genetic engineering. Without these things, if you want to change the attributes of genes, it is basically equivalent to not giving you a scalpel to let you perform surgery. Is it possible?

Seeing what the two said, Karimos asked curiously, "Then... what do the two professors mean?"

Marie Claire shook her head and said, "It's not a bad thing. Professor Chen Cang came in rashly. I think I can teach him a lesson and let him see clearly whether the field of genetic engineering is as simple as it is."

Robert Weinberg wanted to say something, but he didn't say it, and he didn't think it was necessary. If it was really that simple, they wouldn't have been studying it for so many years!

Moreover, the precision of the molecular scalpel they are using now is much ahead of China.

It's like China is using a 3-0 suture and they're already using an 8-0!

"Maybe, Professor Chen will still need our help at that time. At that time, we can also communicate with him about the research method of CN-GV-988 drug!" Marie Claire smiled, "It seems that this is not good for Xinji Group. Bad thing!"

Now, the world is paying attention to CN-GV-988 Alzheimer's disease relief drug.

Marie Claire and the others now have shares in Xinji.

Hearing Marie Claire say this, everyone around immediately fell into deep thought.

Chairman Karimos also nodded thoughtfully.

...

...

At this time, the Second Provincial Hospital of Dongyang Province started a large-scale volunteer announcement.

Free multigene testing for breast cancer patients.

At this stage, the cost of genetic testing is very high, and there are many types!

Moreover, the key point is that the accuracy of multi-gene detection of breast cancer is quite high now.

Therefore, once the news was announced, it immediately attracted many women from all over the world!

The prevalence of breast cancer is quite high now, and many people have to pay attention to it. Free testing is of great significance to many people.

When the news spread, it immediately attracted the attention of countless people.

Everyone couldn't help feeling Qin Xiaoyuan's wealth and grandeur!

And this is also very good for improving your reputation.

Everyone is willing to do the free medical examination.

For this item alone, 300 million worth of funds have already gone out. Qin Xiaoyuan earned a lot of fame here, and he called it working for the welfare of the common people.

The only loss is that Qin Yue clamored to find him every day, saying that this was his child's wife!

After Qin Xiaoyuan told Qin Yue the news of Liu Yukun, the president of the Oncology Association, Ji Ruyun successfully kicked him out of the house!

Of course, Chen Cang has not been idle these days!

In one month, Chen Cang screened more than 2,000 patients for follow-up in-depth research!

A follow-up study was performed on the genes of patients with mutated BRCA1 and BRCA2 genes!

Most of the patients are actively cooperating, after all, BRCA1 and BRCA2 mutation genes mean that the risk of genetic breast cancer is as high as 40% to 80%!

That's right!

Getting to this point is also very simple.

But in the next process, it is getting more and more difficult to continue deriving!

How BRCA1 and BRCA2 genes induce disease!

What is the mechanism of arrival!

This information is actually half-hidden!

Follow their narrative!

Both BRCA1 and BRCA2 are tumor suppressor genes.

Among them, BRCA1 is located on human chromosome 17q21, contains 23 exons, and encodes a protein consisting of 1 863 amino acid residues;

BRCA2 is located on human chromosome 13q12, contains 27 exons, and encodes a protein consisting of 3 418 amino acid residues.

The protein encoded by BRCA1/2 acts on a variety of cell life activities, including DNA damage repair, gene transcription regulation and cell cycle regulation, etc.

Mutations in the BRCA1/2 gene contribute to the development of breast cancer…

Neither Marie Claire nor Robert Weinberg spoke out.

If you want to continue to explore in depth, you need to use a high-precision molecular scalpel to study this gene one by one!

At this time, Chen Cang decided to try his perfect [genetic engineering] method!

The precision of the molecular scalpel determines the precise separation of genes!

It sounds simple, but the difficulty is very high!

Restriction endonuclease is a scalpel!

This is an enzyme isolated and purified from prokaryotes, which can cut foreign DNA. This kind of cutting is carried out inside the DNA molecule, and it is also the most perfect scalpel!

But how?

This requires identifying a specific nucleotide sequence of the DNA molecule, and then breaking the phosphodiester bonds between the nucleotides at specific positions in each chain!

This process is cut!

How to accurately identify and cut precisely, this is the ability of "different molecular scalpels"!

but!

However, in Chen Cang's perfect genetic engineering, there is a more complete molecular scalpel!

and……

My scalpel, the most stylish fashion!

ps: There are a lot of things to check, so I can’t write blindly, everyone forgive me...

Five shifts have been delivered, please support!

This is yesterday.

Today and today.

It's the end of the month, everyone, please vote for the monthly ticket...

Recommend a book by the way!

Ji Cha's new book: "This is My Planet", a daily book combining fairy tales and science fiction, is still a new book.
