In the dust-free laboratory of the medical department of the three-color fire headquarters, Lin Hong was wearing a white experimental suit at the moment, and the whole person was dressed tightly, and even the eyes were covered with transparent plastic sheets. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

In his hand with experimental rubber gloves, he was holding a small test tube, which contained a light blue liquid in a small half tube, which was slightly scattered under the light tube, giving people a very dreamy feeling.

The solution contained in this is the research result of Lin Hong and them for so long, called krad51d, a synthetic molecular culture solution.

This molecule is a targeted protein molecule that specifically destroys the activity of a protein molecule called RAD51D in cancer cells in the human body, which is the telomerase enzyme that causes cancer cells to divide continuously.

RAD51D telomerase repairs the telomeres of cellular chromosomes, thereby preventing cells from dying due to overweight telomere damage.

Inhibition of this telomerase inhibits the ability of cancer cells to divide indefinitely.

In order to find this suitable synthetic molecule, researchers in the Tricolor Fire Medical Laboratory conducted thousands of experiments and tested countless different kinds of protein molecules before finally cultivating KRAD51D.

The name of this synthetic molecule is named by Lin Hong, and it is very simple, the prefix k in front stands for "kill", which means "kill".

Lin Hong used a syringe to extract the light blue solution in the test tube, and then took over the experimental mouse handed over by Si Qian next to him.

This is a mouse that has been infected with tumor cells, on its back. There was a large chunk of tumor tissue that towered high, and if not treated effectively, the poor little mouse would die of organ failure within a few days.

The tip of the needle pierced the mouse's back with precision without a hint of trembling.

After the mouse screamed twice, the blue liquid in the syringe was injected into its body.

The mouse thief's bright eyes rolled, and he didn't know what it meant to him, or why the human in front of him was stabbing him with something sharp. It writhed unconsciously, rubbing its uncomfortable back.

Lin Hong grabbed the mouse and put it in front of him, looked into its eyes and muttered, "Xiaobai." Whether you survive or not depends on your creation. ”

With that, he put it back in the cage.

Xiaobai just landed on the ground. He immediately ran back to his warm nest.

It is not as active as it used to be, it always feels very tired, it wants to sleep at every turn, and it has no interest in even eating.

The place that had just been stung was warm and very comfortable, as if something was spreading there.

Si Qian stared at the mouse for a while, then turned his head and asked, "Lin Hong, did you say that we would succeed this time?" ”

Having failed countless times, they have long been numb, but. This time there were high hopes, and if this time it failed, even she felt that this matter seemed to be impossible at all.

Lin Hong also stared at the guinea pig, did not look back, he said in a firm tone: "We will succeed!" ”

He didn't say this time. Anyway, he was convinced that their efforts would eventually pay off.

At this point, they are getting closer and closer to success.

Lin Hong and Si Qian did not leave, but stayed directly in the laboratory, while they were doing other work, waiting for the results of the ** experiment.

Five hours later, Lin Hong arrived at the rat house on time. As soon as he reached out, he grabbed the mouse.

The little mouse's spirit seemed to be worse at the moment, staying in place and not moving, too lazy to move when he was caught, and glanced at Lin Hong, it continued to squint slightly and doze.

Lin Hong took the syringe from Si Qian's hand and took some blood samples from the body of the mouse.

He then quickly slice the blood sample and put it under a microscope for observation.

Both the blood of the mice and the previous solution of protein molecules have been stained, and these substances can be seen very clearly under the microscope.

The large red cells are cancer cells, while the green spheroids, which are only a few tenths the size of them, are the KRAD51D protein molecules.

Lin Hong saw that these small green molecules had entered the red cancer cells, and the divisions were very uniform, forming a circle around the chromosomes.

Lin Hong breathed a sigh of relief in his heart, the experimental results were in line with expectations, and there was no rejection of this new molecule inside the cancer cells.

Lin Hong turned his head and said to Si Qian, "It's time to take the next step." ”

Si Qian nodded, took the previous blood sample and walked to the side of the culture instrument and equipment, and began to accelerate the cultivation of cancer cells in vitro.

Originally, if they wanted to wait for the results of the experiment, as long as they waited for a few days, they could directly see the changes in the body of the mice, but they simply did not have the patience to wait for so long, and directly withdrew the blood from the body, and cultured the cancer cells as they had cultivated immune cells before, giving them the most suitable temperature and nutrients to accelerate their division.

If the synthesized KRAD51D is effective, it should follow a predetermined process to "alternately protect" the telomeres of the cancer cell chromosomes, thereby indirectly inhibiting the effect of telomerase on telomeres, making them look like a normal cell, and after a limited number of divisions, it will die normally.

Si Qian diluted the blood sample, added the prepared nutrient solution and filtration solution, and then put it in the incubator for cultivation.

The nutrient solution provides nutrients for cell division.

The filtration solution mainly kills immune cells so as not to affect the normal division of cancer cells.

The incubator is a special equipment made of imitation of the human environment, the temperature inside is the most suitable temperature for the human body, and it is also the most suitable temperature for cell division, at this temperature, the cancer cells in the blood sample are the most active, plus there is enough nutrition in the solution, and there is no natural enemy immune cells to harass and attack, they will divide and multiply with the fastest speed and highest efficiency.

This process is many times faster than normal division and reproduction in the human body, and a process that would have taken several days to complete can be completed in just a few hours in an incubator.

Then came another difficult time of waiting.

Lin Hong said to Si Qian: "You go and rest for a while, just have me here." ”

Si Qian didn't refuse, nodded, and said, "Okay, I'll go take a nap for a while, if there's anything, call me immediately." ”

Their project is not a matter of one or two days, half a year has passed, and there is no rush for this time.

Si Qian left the dust-free laboratory, took off her lab coat in the locker room, and then went to the lounge next door.

Lin Hong continued to study the molecular model of KRAD51D in his mind, this model he was already too familiar with, and sometimes he could dream of it.

This molecule is actually carefully designed by Lin Hong, and it is more like a mechanical part than a biological tissue, except that the material used is a biological tissue.

This molecular model has been improved and upgraded countless times so far, and Lin Hong can even control it precisely like a control machine.

Once the experiment is successful, the use of this molecule is not limited to cancer treatment.

Just as Lin Hong was thinking, there was a sudden "ding" sound in his ears.

The time set for the incubator has arrived.
