The phrase "a point upstream of" is correct and usable in written English.
It can be used in contexts related to flow, direction, or position, often in discussions about rivers, streams, or processes that move in a particular direction.
Example: "The water quality was tested at a point upstream of the industrial discharge."
Alternatives: "a location prior to" or "a site before".
During the H2 regime, three watersheds with greatest glaciated surfaces straddling the Karakoram Mountains contribute 48 54% of flows at Shatial Bridge, a point upstream of Tarbela reservoir up to which rainfall contributions to river discharges in UIB are inconsequential.
In addition we have traced the effects of JNK to a point upstream of Caspase 8 cleavage.
This suggests that anisomycin sensitises DU 145 cells to Fas mediated apoptosis at a point upstream of Caspase 8 cleavage, probably during DISC formation.
The basic mechanism responsible for the biogenesis of circular RNA involves a 'backsplicing' reaction in which a branch point upstream of a circularized exon attacks a downstream splice donor, positioning the 3′ end of the exon to attack its own 5′ end in the second step (Braun et al., 1996; Pasman et al., 1996; Schindewolf et al., 1996).
The TSC2/TSC1 complex, which has a tumor suppressor function in various cancers, is a key point upstream of mTORC1 since TSC2/TSC1 can suppress mTORC1 by inactivating the mTORC1-interacting protein, Rheb [25], [26].
Each run shows a discontinuity in the field strength in the sub-flow point upstream of Titan.
However, NLV do survive high levels of chlorination (3, 8 ), and the treatment was performed only once, at a late stage of the outbreak, and at only one point upstream of the resort water system.
This suggests that the target(s) of vhs is not these mRNA transcripts, but rather at some point upstream of their expression.
Sox2 could potentially regulate TE formation in the preimplantation embryo at some point upstream of Tead4, since Tead4 expression is affected in the absence of Sox2 (this study) but Sox2 is not affected in the absence of Tead4 [39].
As predicted by both models, qPCR confirmed that the branch point upstream of the circularized exon and the 5′ ss in intron 2 are both necessary for circularization to occur.
