In gestational implantation, endometrium stromal cells are the real VIPs. These cells need to be receptive and ready, especially for human conception. Something called SHP2, a protein, is highly present in these decidualized cells. Its role here? Making the cells that line the uterus receptive to implantation.

But, what is SHP2 doing there exactly? Why is SHP2 expressed? We don't know, but we know its function depends on its interactions.

These decidual cells play a major part in the early stages of a healthy pregnancy.  And they need to communicate well with things called signaling pathways.  To decipher the importance of SHP2, we used a name-prognosis called proximity-dependent biotinylation.

Some of the most important gene functions to a healthy pregnancy include Beta-enolase (Eno3), a gene that provides a source of energy for tissues.  Pyruvate kinase 2 (Pkm2) is an enzyme involved in vital metabolic pathways and Glycolyse. Glutaminerkinase and Aldolase C make up the molecules that act as transporters. That's some doozy science terms!

Now, let's zoom out to look at the bigger picture. It's increasingly clear that SHP2 has a big role to the cellular level of decidual activity.  As SHP2 becomes more expressed in decidual cells, HIF1α is activated. This allows decidual cells to communicate well with other pathways. In a nutshell, SHP2 influences the amount of lactate present in the cells.

Oxygen deprivation and how this influences our cells is a fascinating field of study. Can high levels of SHP2 influence the lack of oxygen present in cells in the endometrium? Does it make the cell environment become more favorable for a healthy implantation?

Two potential answers to these questions are suggesting that SHP2 is a key player in enhancing the expression of Hypoxia-inducible factor-1. And that it interacts with HIF-1α. This interaction plays a crucial factor in our cells to survive during hypoxia.

Now, let's try to wrap our heads around some more confusing terms.

To prevent oxygen deprivation, cellular oxygen sensors called prolyl hydroxylases turn on HIF-1α and protect the cells. In this study, it has been found that Hypoxia-inducible factor-1 reacts to the lack of oxygen in cells.

When cells are under oxygen deprivation, they produce pyruvate. Pyruvate must be converted into lactate, an energy source that doesn't require oxygen.  And that part is the brainchild of Beta-enolase and Pyruvate kinase 2.

Aldolase C is another enzyme in the same family as Aldolase. It breaks down food molecules for necessary energy. A transporter molecule responsible for the transfer of energy is called Facilitative glucose transporter 1.

These findings reveal some mind-blowing mechanisms that sheds light on this intricate cellular process. It also provides a solid base for further research in the field of cellular biology.

In a nutshell, this is what the researches have found. When SHP2 is blocked, the expression and activation of HIF-1α and genes related, reduced even lactic acid.  To finalize that SHP2 is more than just a std. sensor for lack of oxygen in cells.

When oxygen is removed and the cells are forced to stress out is the way the protein acts and they respond.  With more studies, we may find even more.  But for now, the answer of how cells adapt to lack of oxygen is still to be discovered.

The research has been a major breakthrough in our understanding of cellular biology.
