Mast cells typically express modest levels of LTC4S and its up-regulation can be mediated by IL-4 (but not by IL-5 or IL-13).
In a cell line expressing low levels of EGFR receptor (Fig. 1D), the combination of Sirolimus and Nimotuzumab is highly synergistic although the effect of Sirolimus is modest while Nimotuzumab has no effect in these cells (Fig. 1E).
Pericyte-2 cells expressed Agtr1a, Vsnl1, and Art3, but lacked or expressed low levels of Acta2.
As expected, under normoxic and un-stimulated conditions, the hepatocytes expressed only modest levels of both EPO and EpoR gene expression as absolute value.
Forced RAD21 expression was also attempted in the HCT116 cell line (harbouring KRAS mutation), which expresses only modest levels of RAD21.
Although the presently used cells express only modest levels of drug transporter proteins, such as MDR1 and MRP1, we tested for the possible involvement of these proteins in the observed C6-SM effect on doxorubicin uptake.
However, chronically stimulated murine "adapted" T cells do not express CD69, and express a modest level of PD-L1 [29], contrary to human TIL, that express CD69 but not PD-L1 (our data).
This was also observed to a lesser extend in BT-474 cells that express a modest level of CDKN1C, and at low rates in MDA-MB-231 and MCF10A cells that express abundant CDKN1C.
Not surprisingly, recombinant routes have been explored and the enzyme can in fact be produced by microbial fermentation [ 30], animal cell culture [ 31, 32], and transgenic goats [ 33] and stably or transiently expressed in Nicotiana, albeit at modest levels of 20 200 mg/kg fresh weight (FW) biomass [ 29, 34, 35], with yield improvements being the target of ongoing research.
GENEVA — As Syria's crisis moves into its third year, international relief agencies are expressing alarm at the slow arrival and modest levels of financial support they are receiving to help the tens of thousands of civilians who have been fleeing the conflict and the millions trapped inside the country whose plight becomes more desperate.
